The SX011832 crossed roller bearing measures 160 × 200 × 20 mm and combines a large 160 mm through-bore with a compact 200 mm outside diameter. It is designed for direct-drive rotary axes, hollow-shaft automation, welding positioners and semiconductor transfer equipment.
Its crossed roller arrangement supports radial, axial and tilting-moment loads in one bearing position. The SX011832 provides a dynamic axial load rating of 69 kN, a static axial rating of 272 kN and an approximate mass of 1.7 kg.
LYDL can supply P5, P4, P2 or customized accuracy, together with application-specific clearance or preload. Proper selection should account for motor heat, housing rigidity, mounting accuracy, starting torque and operating temperature.
Dimensional interchangeability does not guarantee identical preload or running accuracy. Submit the complete original designation and suffix when replacing an INA/Schaeffler or another manufacturer’s bearing.
SX011832 Crossed Roller Bearing Overview
The SX011832 crossed roller bearing is a precision rotary bearing with a 160 mm bore, 200 mm outside diameter and 20 mm width. It offers a practical balance between a large hollow passage, compact installation dimensions and stable combined-load capacity.
An integrated inner ring provides stable shaft-side rotation. The circumferentially split outer ring simplifies assembly and must be uniformly retained by a rigid housing cover or clamping flange.
SX011832 is particularly suitable for equipment in which cables, air lines, vacuum lines, optical components or drive elements must pass through the center of rotation. Its approximate mass of 1.7 kg also supports responsive servo-controlled motion.
For additional sizes and an overview of the complete design range, visit the LYDL SX crossed roller bearing series. The main image should clearly show the slim cross-section, integrated inner ring and split outer-ring structure. A clean white background is recommended for product recognition and Google image indexing.
The listed load ratings are catalogue reference values and should not be treated as the maximum permissible equipment loads. Bearing selection must consider the actual radial, axial and moment loads, operating cycle, speed, lubrication, temperature and required service life.
Ratings published by different manufacturers may vary because of differences in internal geometry, roller quantity, materials and calculation assumptions. Use one manufacturer’s complete dataset instead of combining individual values from several brands.
For a broader explanation of bearing structures, load directions and selection principles, refer to the LYDL crossed roller bearing selection guide.
Why Choose the SX011832?
Balanced Bore-to-Outside-Diameter Ratio
The 160 mm bore occupies a large proportion of the 200 mm outside diameter. This allows designers to create a compact hollow-axis mechanism without using an excessively large housing.
Combined-Load Support
Cylindrical rollers are arranged alternately at 90 degrees. This enables the bearing to support radial loads, axial loads and overturning moments in one bearing position.
Suitable for Hollow-Axis Integration
The central opening can accommodate a torque-motor rotor, encoder, slip ring, electrical cables, pneumatic tubes or vacuum connections. These components must be positioned so that they do not contaminate or heat the open bearing.
Controlled Rigidity and Running Torque
Application-specific clearance or preload can be selected according to rigidity and positioning requirements. Preload should be balanced against starting torque, motor capacity and operating temperature.
Compact Axial Width
The 20 mm bearing width helps reduce the axial length of the rotary mechanism. A shorter structure can also reduce the distance between the external load and the bearing center.
Main Applications
Direct-Drive Rotary Axes
SX011832 can support compact torque-motor rotary stages requiring a 160 mm hollow passage. Motor-generated heat, rotor imbalance and electromagnetic forces should be included in the engineering review.
A preloaded configuration may improve reversal accuracy and angular rigidity. The motor must still provide sufficient starting and continuous torque under the selected preload and lubricant conditions.
Welding and Assembly Positioners
The bearing is suitable for indexing fixtures carrying workpieces, clamps and welding tooling. Fixture eccentricity, sudden stopping loads and cable or hose resistance must be evaluated.
External protection is important because the standard SX011832 is open. Welding dust and metal particles must be prevented from entering the raceways.
Semiconductor Transfer Equipment
Its large through-bore and compact outside diameter support wafer-transfer modules, vacuum-handling mechanisms and precision automation axes.
Clean-compatible lubricant, controlled assembly and special packaging should be specified when the bearing will be used in semiconductor or cleanroom equipment.
Hollow-Shaft Automation Modules
The central passage can carry cables, air lines, vacuum tubes or sensor connections through a rotating assembly. Cable routing must prevent friction, bending damage and contact with the bearing lubricant.
SX011832 is also suitable for automated inspection turntables where cameras, sensors or workpiece fixtures require repeatable indexing. The image can combine four realistic application scenes:
Direct-drive rotary axis
Welding or assembly positioner
Semiconductor transfer equipment
Hollow-shaft automation module
The four applications should be combined into one image with short English labels. Keep the lighting, colors and image style consistent.
SX011832 is suitable when a 160 mm central passage is sufficient and its calculated load margin meets the application requirements.
SX011836 offers a significant capacity increase but requires a larger 225 mm outside diameter. SX011828 is more compact but provides a smaller central passage and lower static capacity.
If the application requires a different inner-ring and outer-ring structure, customers can also compare the LYDL RB series crossed roller bearings.
Accuracy and System Performance
LYDL can supply SX011832 in P5, P4, P2 or customized accuracy classes.
P5 is suitable for many industrial rotary axes and automation mechanisms. P4 or P2 may be selected for machine-tool, optical or measuring applications with more demanding runout requirements.
Final system accuracy is affected by:
Bearing running accuracy
Shaft-seat roundness
Housing-seat geometry
Mounting-face flatness
Flange parallelism
Screw-tightening consistency
Drive-component eccentricity
Encoder installation
Thermal deformation
Installing a P2 bearing in an inaccurate or flexible housing will not automatically produce P2 system-level rotation.
Internal Clearance and Preload
A bearing with internal clearance generally produces lower friction torque and is less sensitive to mounting error. It may be suitable for applications without demanding angular-rigidity requirements.
Controlled preload can reduce elastic displacement and improve reversal accuracy. It may be preferred for direct-drive axes, inspection platforms and precision indexers.
Excessive preload can increase starting torque, heat generation and sensitivity to housing deformation. The required preload should be selected together with the drive motor, lubricant, mounting fits and operating temperature.
When requesting a quotation, specify whether the application requires standard clearance, reduced clearance or preload.
Suffix and Designation Explanation
Suffixes are manufacturer-specific and should not be removed from an inquiry or purchase order.
In Schaeffler technical documentation, examples may include:
RL0: reduced internal clearance
VSP: defined preload
RR: Corrotect-coated configuration
A: may identify a particular design generation
These suffix meanings are not automatically transferable between manufacturers. Confirm the exact configuration using the original drawing, catalogue or inspection document.
An SX011832-A-VSP, for example, should not automatically be replaced by an unsuffixed SX011832.
Replacement and Interchangeability
SX011832 and LRC 16020 may be used as dimensional interchange references. Functional interchangeability requires additional technical verification.
Before confirming a replacement, compare:
Complete original designation and suffix
Bore, outside diameter and width
Dimensional tolerances
Accuracy class and runout
Internal clearance or preload
Starting and running torque
Load-rating basis
Material and heat treatment
Lubricant
Coating or corrosion protection
Required inspection documents
LYDL can review the original bearing label, drawing, catalogue page or inspection report before confirming interchangeability.
Third-party brand names are used only for technical identification and comparison. Their use does not imply authorization, affiliation or original-brand manufacture.
Housing and Mounting Guidance
The split outer ring requires continuous and uniform retention. It must be clamped by a sufficiently rigid housing cover or flange.
A reference mounting arrangement may use 24 × M8 flange screws, but this is not a universal design requirement. Final screw diameter, quantity, strength class and tightening torque must be calculated for the actual housing and external loads.
Both mounting faces should be accurately machined, clean and free from burrs. Uneven coatings, local high points and flange waviness may distort the raceways.
Tighten flange screws gradually in a diagonal sequence. Rotate the bearing during tightening and monitor any change in starting or running torque.
For an aluminum housing, account for the difference in thermal expansion between aluminum and bearing steel. Temperature changes may alter the effective fit, clearance or preload.
The housing flange should transmit the working loads. Retaining screws or shipping elements must not be treated as substitutes for a properly designed structural load path.
Lubrication and External Sealing
The standard SX011832 is an open bearing without integral seals. External protection is required where dust, coolant, moisture, welding particles or machining debris may enter the raceways.
Grease should be selected according to:
Rotational speed
Oscillation angle
Operating temperature
Applied loads
Required service life
Cleanliness requirements
Relubrication method
Avoid excessive grease filling. Too much grease can increase rotational resistance, temperature and motor load.
For direct-drive equipment, verify that the selected lubricant and sealing system are compatible with the available starting and continuous motor torque.

Frequently Asked Questions
1. What is the principal advantage of the 160 mm bore?
The large bore provides space for a hollow shaft, torque-motor rotor, slip ring, encoder, vacuum piping or electrical cables while keeping the outside diameter at 200 mm.
2. Can SX011832 be used with a direct-drive torque motor?
Yes, subject to engineering verification. Motor heat, electromagnetic forces, rotor balance, bearing preload and available motor torque should be reviewed together.
3. Is SX011832 suitable for oscillating index movements?
Yes. Lubrication must suit the oscillation angle because very small repetitive movements may not redistribute grease across the entire raceway.
4. Does higher preload always improve positioning accuracy?
No. Higher preload may improve rigidity but can also increase friction torque and temperature. Excessive preload may reduce service life.
5. What should be checked when using an aluminum housing?
Check thermal expansion, flange thickness, screw spacing, mounting fits and face flatness. Aluminum expansion may change the bearing’s effective preload.
6. Can a suffixed INA/Schaeffler bearing be replaced by LRC 16020?
Only after the suffix and performance requirements have been reviewed. Nominal dimensions alone do not confirm functional interchangeability.
7. Does SX011832 require an external seal?
Usually yes in contaminated environments because the standard bearing is open. The seal should protect the raceways without creating excessive drag.
8. Which checks are recommended after assembly?
Measure starting or running torque, radial and axial runout and, where applicable, axial displacement under a controlled test load.
