21304 CAM/C3W33 BLT

Spherical Roller Bearings utilize 2 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. These high capacity bearings perform consistently in adverse conditions such as shock loads, shaft deflections, marginal lubrication, extreme speeds, contamination and critical application stresses ~~ Sperical Roller Bearings are constructed with a Brass, one-piece CAM cage. As compared with the older style MB cage, this design allows for a longer roller and higher overall load carrying capacity, providing better performance and greater life. ~~ To facilitate efficient lubrication, these bearings are equipped with an annular groove and lubrication holes in the outer ring (W33). C3 interal clearnce (Fit) provides for component expansion during operation at moderate temperatures. ~~ Due to their superior design capabilities, Spherical Roller bearings are used in a wide vareity of applications including: windpower, mining, pulp & paper, power generation, shipping and cargo operations, oil field, aggregate, gear drives, and rolling mills.
