RB Series Crossed Roller Bearings

(RB series, CRB series, NRXT series)

RB series crossed roller bearings is the basic type of crossed roller bearings, in which the outer ring is separable while the inner ring is integrated with main body. Outer ring is divided into two parts, and the inner ring rotating.

This type is suitable for these parts that need an inner ring with high precision.

That's the reason why RB series crossed roller bearings been widely used in the field of Industrial robots, Medical appliance, Revolving tables of machining centers, Precision rotary tables, Indexing Table, Military Radar, etc.

Crossed Roller Bearing Installation and Maintenance Guide

1. Prepare Mounting Surfaces

Clean the housing, shaft, and any contact surfaces to remove dirt, dust, or debris. Ensure all burrs or sharp edges are smoothed to prevent damage during installation.

2. Bearing Insertion

Thin-walled bearings are prone to tilting. Gently tap the bearing into the seat or onto the shaft using a plastic mallet. Strike evenly around the circumference in small increments until the bearing is fully seated. Confirm alignment through visual inspection and tactile feedback.

3. Lubrication

Apply the recommended grease or oil evenly to all rolling elements and raceways before first operation. Ensure complete coverage while avoiding over-lubrication, which can increase temperature and leakage.

4. Preload and Clearance Adjustment

Check axial and radial clearances according to the bearing series specifications. Apply preload gradually for bearings requiring it, ensuring proper stiffness without overloading. Correct clearance is essential for smooth rotation, high rigidity, and long service life.

5. Final Inspection

Manually rotate the bearing to ensure smooth, even movement. Listen for unusual noises and feel for resistance. Verify that the bearing is fully seated and aligned before starting operation.

6. Operational Monitoring

During initial use, monitor temperature, vibration, and noise levels. Ensure proper lubrication and alignment, and adjust if necessary to maintain optimal performance.
