21307 CAM/C3W33 BLT

Spherical roller bearings utilize two rows of rollers operating in a common sphered outer ring raceway. This design provides a self aligning solution that is the combination of a radial and thrust bearing that operates even if the shaft and housing are, or become, misaligned under load. This high capacity bearing performs consistently in adverse conditions such as shock loads, shaft deflections, marginal lubrication, extreme speeds, contamination and critical application stresses. BL® spherical roller bearings are constructed with a bronze, one-piece CAM cage. As compared to the older style MB cage, this design allows for a longer roller and higher overall load-carrying capacity, providing better performance and greater life.
