📘 Bearing Cross Reference Chart
Use the bearing interchange chart below to identify equivalent bearing part numbers from various manufacturers. This tool is especially useful when replacing obsolete or brand-specific bearings with compatible alternatives.
🔹 Common Bearing Types Covered:
- Miniature Bearings
Precision small-diameter ball bearings used in compact applications such as instruments, robotics, and medical equipment. - Flanged Ball Bearings
Designed with a flange on the outer ring to simplify positioning during mounting. - Thin Section Bearings
Bearings with a small cross-section designed to save space and reduce weight without compromising performance. - Slewing Ring Bearings
Large diameter bearings capable of handling axial, radial, and moment loads; often used in cranes, wind turbines, and heavy equipment. - Cam Followers (Track Rollers)
Special roller bearings designed to follow cam lobes or tracks, commonly used in automated machinery. - Needle Roller Bearings
Bearings with long, thin rollers that provide high load capacity in compact radial spaces. - Self-Aligning Ball Bearings
Bearings with a spherical outer raceway that allows for misalignment between shaft and housing. - Spherical Roller Bearings
Designed to accommodate heavy radial and axial loads, suitable for demanding industrial environments. - Thrust Ball Bearings
Bearings designed to support axial loads in one direction, used in low-speed, low-load applications.
