NSK self lubricating ball bearings

RHP Self-Lube®, Silver-Lube®, Life-Lube and Molded-Oil units include two basic components, the insert and the housing. Each unit consists of a sealed single-row ball bearing with spherical outside diameter and extended inner ring mounted in a pillow block or flanged housing.  The spherical fit accommodates initial misalignment. 

Self Lubricating Bearings are available with a range of locking methods for close-fit shaft mounting. This feature combined with a complete range of sealing for all environments makes our units a very versatile product.
