The RB3510 cross roller bearing measures 35 mm in bore diameter, 60 mm in outside diameter and 10 mm in width. Its crossed cylindrical roller arrangement supports radial loads, axial loads in both directions and overturning moments within a compact bearing envelope.
Featuring an integrated inner ring and split outer ring, RB3510 is suitable for small robot joints, compact rotary tables, measuring instruments, optical inspection equipment and precision positioning mechanisms. It provides a basic dynamic radial load rating of 7.64 kN and a basic static radial load rating of 9.12 kN.
Precision grade, clearance, preload, sealing and lubrication options can be confirmed according to the operating conditions and approved mounting drawing.
RB3510 Cross Roller Bearing Overview
The RB3510 cross roller bearing is a compact precision bearing with a 35 mm bore, 60 mm outside diameter and 10 mm width. It is designed for rotary mechanisms that require combined-load capacity, high rigidity and accurate positioning within limited installation space.
Cylindrical rollers are arranged alternately at 90 degrees between the inner and outer raceways. This crossed arrangement enables a single RB3510 bearing to support radial loads, axial loads in both directions and overturning moment loads.
The RB3510 uses an integrated inner ring and a split outer ring. This structure is commonly selected where accurate inner-ring rotation, compact dimensions and stable rotational behaviour are required.

*Mounting dimensions are catalogue references. Final shaft, housing, flange and chamfer dimensions must follow the approved LYDL drawing supplied with the quotation or order.
The load ratings are basic radial ratings used for bearing selection and life calculations. They are not direct maximum allowable application loads. Combined radial, axial and moment loads must be evaluated using appropriate equivalent-load calculations and safety factors.
Structure and Operating Principle
Adjacent cylindrical rollers inside the RB3510 are arranged with their axes crossing at right angles. The rollers make line contact with the raceways, providing greater rigidity than a comparable point-contact ball-bearing arrangement.
This internal geometry enables the bearing to carry:
Radial loads
Axial loads in both directions
Overturning moment loads
Combined radial, axial and moment loads
The integrated inner ring provides a continuous raceway for accurate inner-ring rotation. The split outer ring facilitates assembly of the rollers and separators.
Outer-ring retaining screws are generally intended to prevent separation during transportation and installation. They must not be treated as structural mounting bolts unless the approved drawing specifically states otherwise.
Key Advantages of RB3510
Compact 35 mm Bore Design
The 35 mm bore and 60 mm outside diameter make RB3510 suitable for small rotary mechanisms where installation space and total assembly weight must be controlled.
Combined-Load Support
One bearing can support radial, bidirectional axial and overturning moment loads, helping simplify the surrounding bearing arrangement.
High Rigidity for Its Size
The crossed cylindrical roller geometry provides resistance to tilting deformation and supports stable positioning under combined loads.
Low Bearing Mass
With an approximate mass of 0.13 kg, RB3510 is suitable for compact moving mechanisms where inertia and total component weight are important.
Space-Efficient 10 mm Width
The 10 mm bearing width helps reduce the axial length of small robot joints, inspection devices and precision rotary mechanisms.
Configurable Precision
Accuracy, clearance, preload, sealing and lubrication can be specified according to the required runout, rigidity, running torque and working environment.
Suffixes for seals, clearance, preload and accuracy are manufacturer-specific. The following RB3510 designations should be treated as enquiry examples rather than universal catalogue codes.
The final LYDL order designation and numerical requirements must be confirmed in the quotation.

Technical review and availability
Seal Suffixes
No suffix: Normally indicates an open configuration, but the supplied condition must be confirmed.
U: Commonly indicates a seal fitted on one side. The required seal orientation should be specified.
UU: Commonly indicates seals fitted on both sides.
Clearance and Preload Suffixes
CC0: Used in the THK designation system for controlled negative clearance or preload.
C0: A defined clearance category. In the THK system, C0 indicates positive clearance and should not automatically be interpreted as zero clearance.
C1: A manufacturer-specific positive-clearance category.
Clearance and preload affect rigidity, running torque, positioning behaviour and temperature rise. For precision orders, the numerical range should be included in the technical agreement.
Accuracy Suffixes
P6: Accuracy class 6
P5: Accuracy class 5
P4: Accuracy class 4
P2: Accuracy class 2
PE5, PE4 or PE2: THK-style codes combining rotational and dimensional accuracy requirements
A higher accuracy grade should be selected only when the shaft, housing, flange and assembly process can preserve the specified bearing accuracy.
Same nominal boundary dimensions but different ring structure

Important Difference Between RB3510 and CRBH3510A
IKO CRBH3510A has the same nominal 35 × 60 × 10 mm boundary dimensions, but it belongs to IKO’s high-rigidity series with both inner and outer rings manufactured as one-piece components.
RB3510 uses an integrated inner ring and a split outer ring. Therefore, CRBH3510A should be treated as a dimensional selection reference, not an automatically interchangeable equivalent.
Differences may include:
Inner and outer ring construction
Mounting and clamping method
Shoulder dimensions
Roller and separator arrangement
Load ratings
Clearance or preload
Rotational accuracy
Sealing and lubrication
Running torque
No direct NSK NRXT3510 standard model has been confirmed in the reviewed N Series catalogue. The designation should not be used as a replacement keyword or interchange claim without an official NSK drawing.
Material, Sealing and Lubrication
Depending on the confirmed specification, bearing-steel options can include GCr15, GCr15SiMn or 100Cr6.
Open bearings require suitable lubrication and an effective external sealing system. Sealed versions provide additional protection against dust ingress and grease leakage but may produce higher starting and running torque.
Lubricant selection should consider:
Rotational speed
Applied loads
Operating cycle
Temperature range
Required running torque
Environmental contamination
Relubrication interval
Compatibility with surrounding materials
Do not mix greases with unknown base-oil or thickener compatibility.
Inspection and Quality Control
Inspection requirements should be agreed before production. Depending on the order specification, the inspection scope may include:
Bore and outside-diameter measurement
Bearing width inspection
Dimensional and rotational runout
Radial clearance or preload verification
Starting and running torque
Rotation smoothness
Raceway and surface-condition inspection
Hardness verification
Cleanliness inspection
Laser marking verification
Appearance and packaging inspection
Material certificates, inspection records or additional documentation should be requested before order confirmation.
Installation Recommendations
To preserve RB3510 accuracy and operating performance:
Clean the bearing, shaft, housing, flange and mounting surfaces.
Remove burrs, contamination and raised edges from all mating surfaces.
Confirm the shaft and housing tolerances against the approved drawing.
Apply installation force only to the ring being fitted.
Never transmit mounting force through the rollers.
Do not strike the bearing directly.
Support the split outer ring during handling and installation.
Tighten flange bolts gradually in a diagonal sequence.
Apply uniform clamping force around the complete circumference.
Check running torque and rotational smoothness after mounting.
Protect open bearings against contamination and lubricant loss.
Inspect final runout after the complete rotary assembly has been installed.
Because RB3510 is a compact bearing, small mounting errors, burrs or uneven flange pressure can significantly affect installed runout and running torque.
