Applications
Industrial transmissions, gearboxes, rotating machinery, heavy equipment and replacement projects where the original design calls for this bearing specification. Application suitability must be checked rather than inferred from the part number alone.
Bearing Design
Tapered rollers and tapered raceways provide a load path for radial forces and axial forces in the supported direction. The exact assembly arrangement, cup/cone geometry, cage type and clearance or preload requirements must be verified before installation.
