Rolling Elements for Bearing Repair and Replacement

Application

Application Challenges

Unknown Original Data

Older bearings may have incomplete drawings or unavailable OEM information.

Raceway Wear

Used raceways may require adjusted roller size or repair allowance.

Matching & Grading

Replacement rollers must be matched for load sharing and clearance.

Profile Compatibility

Original rollers may include crown, logarithmic profile or special ends.

Small Batch & Urgency

Maintenance projects often require limited quantities with short lead times.

Products

Recommended Rolling Elements

Cylindrical Rollers

High radial load capacity, high rigidity and low friction. Diameter, length, end geometry and profile can be customized.

Tapered Rollers

Designed for combined radial and axial loads. Large-end diameter, small-end diameter, angle and end profile can be customized.

Spherical Rollers

Designed for self-aligning spherical roller bearing structures under heavy loads and misalignment. Curvature and geometry can be customized.
