The RB6013 cross roller bearing measures 60×90×13 mm, with basic radial load ratings of 18.0 kN dynamic and 24.3 kN static. Its 60 mm through-bore and compact 13 mm width suit precision rotary assemblies that require high rigidity and limited axial space.
The bearing uses an integrated inner ring and a split outer ring. Cylindrical rollers arranged alternately at 90° allow one compact bearing to support radial loads, axial loads and overturning moments.
Typical applications include industrial robot joints, indexing tables, semiconductor equipment, optical inspection systems, medical devices and precision automation machinery.
LYDL offers P5, P4 and P2 accuracy options, clearance or preload control, open or sealed configurations, lubrication selection and OEM support, subject to technical confirmation.
RB6013 Cross Roller Bearing Overview
The RB6013 cross roller bearing is a compact precision bearing with a 60 mm bore, 90 mm outside diameter and 13 mm width. Its crossed roller arrangement provides high rigidity, accurate rotary positioning and simultaneous support for radial loads, axial loads and overturning moments.
Compared with the RB5013, the RB6013 provides a larger through-bore while retaining the same 13 mm axial width. It is therefore well suited to compact rotary mechanisms that require additional space for shafts, cables, pneumatic lines or optical components.
For additional bore sizes and load capacities, see our complete RB Series Cross Roller Bearingsrange.
The stated load ratings are catalogue-reference basic radial ratings, not maximum permissible operating loads. Final selection must also consider combined loading, speed, duty cycle, lubrication, mounting rigidity, temperature and required service life.
Design and Operating Principle
The RB6013 uses an integrated inner ring and a split outer ring. Cylindrical rollers are arranged alternately at right angles along a single raceway. Adjacent rollers therefore carry loads in different directions.
This arrangement enables one bearing to support:
Radial loads
Axial loads in both directions
Combined radial and axial loads
Overturning moments
The crossed roller structure can simplify a precision rotary support that might otherwise require two conventional bearings. Any such replacement must still be verified through load, rigidity, service-life and mounting calculations.
The structural description is consistent with established RB-type bearing information published by THK and IKO. Relevant official sources are listed in the Technical References section.
Key Benefits of RB6013
Compact 13 mm Width
The slim axial section helps reduce the overall height and mass of robot joints, rotary tables and precision positioning mechanisms.
Large 60 mm Through-Bore
The central opening provides routing space for drive shafts, wiring, pneumatic tubing, optical paths and other services.
High Moment Rigidity
The crossed roller arrangement helps resist tilting under overturning moments, supporting stable positioning in compact assemblies.
Combined Load Capability
A single RB6013 can support radial, axial and moment loads simultaneously when correctly selected and installed.
Configurable Precision
Accuracy grade, internal clearance, preload, sealing and lubrication can be specified according to the application, subject to technical review.
Typical Applications
RB6013 is commonly considered for precision equipment that requires a 60 mm central opening and stable rotary positioning.
Typical applications include:
Industrial robot joints
Robot positioners and end-effectors
CNC indexing tables
Compact rotary and tilting tables
Semiconductor production equipment
Optical inspection systems
Coordinate-measuring equipment
Medical diagnostic equipment
Camera and sensor platforms
Automated assembly machinery
Need an RB6013 Drawing or Quotation?
Send your required quantity, accuracy grade, operating loads, speed and mounting information to sales@luoyangdeeplink.com. Our engineering team can review the application before confirming the bearing configuration and quotation.
Choose the RB5013 Cross Roller Bearing when a 50 mm bore is sufficient and minimum outside diameter is important.
Choose the RB6013 when the assembly requires a 60 mm through-bore, compact 13 mm width and higher static radial capacity than the RB5013.
Choose the RB7013 Cross Roller Bearing when a 70 mm bore and additional static radial capacity are required.
This comparison is intended for preliminary model selection. Actual radial load, axial load, overturning moment, speed, duty cycle and required service life must be evaluated before the final model is confirmed.
Accuracy, Clearance and Preload Options
RB6013 bearings may be supplied in P5, P4 or P2 accuracy configurations, subject to order confirmation and the agreed inspection specification.
P5 is suitable for general precision machinery and automation.
P4 may be selected for higher-accuracy positioning and machine-tool applications.
P2 is intended for demanding rotational-accuracy requirements and requires careful control of the complete mounting system.
Internal clearance or preload should be selected according to operating load, torque, stiffness, temperature and mounting fit. Excessive preload may increase friction and heat, while insufficient preload may reduce system rigidity.
Designations such as RB6013UUCC0 should be treated as manufacturer-specific reference codes. Please provide the complete model, drawing or required configuration when requesting a quotation.
Materials, Sealing and Lubrication
Standard rings and rollers can be manufactured from high-carbon chromium bearing steel such as GCr15 or 100Cr6, depending on the confirmed specification.
Open or sealed configurations may be available. Lubrication should be selected according to speed, temperature, torque, contamination level, maintenance interval and operating environment. Special grease or environmental requirements must be confirmed before production.
Quality Control
Depending on the agreed specification, RB6013 inspection may include:
Boundary dimension inspection
Raceway roundness and geometry inspection
Surface roughness inspection
Hardness verification
Radial and axial runout inspection
Clearance or preload verification
Starting and running torque inspection
Cleaning, appearance and packaging inspection
Required inspection documents and acceptance limits should be agreed before production.
Installation Recommendations
Correct installation is essential for achieving the required accuracy and operating life.
Clean the bearing, shaft, housing and mounting surfaces.
Confirm that the mounting dimensions match the approved drawing.
Check shoulder flatness, perpendicularity and structural rigidity.
Do not apply impact force directly to the bearing rings or rollers.
Support and clamp the split outer ring evenly.
Tighten mounting bolts gradually in a diagonal sequence.
Avoid transmitting installation force through the rolling elements.
Check running torque, noise and runout after final tightening.
Protect open bearings from dust and contamination during assembly.
Housing fit, shaft fit and bolt torque depend on the actual application and should not be selected from the bearing dimensions alone.
Cross-Reference Guidance
CRB6013 and NRXT6013 may appear as preliminary cross-reference designations for 60×90×13 mm crossed roller bearings.
