HOUSED BEARING ASSEMBLY WITH SEALED ROLLER

摘要

A housed bearing assembly suitable for use as a pillow block bearing unit or flanged bearing unit. The assembly includes a shaft sleeve (21) and roller body (23) secured to one another and enclosed by a housing (10). The roller body (23) is adapted to rool against an inner peripheral surface of the housing (10). A supply of lubricant sufficient to lubricate the roller body (23) is contained within the housing. The housing (10) and rolling body (23) are designed to direct lubricant toward fluid tight areas of the assembly and away from those areas where leakage might occur. A lubricant containment reservoir is formed in either the housing or the shaft such that lubricant will not reach the space or interface betwen the shaft and the housing. The roller body may be provided with a drip edge to further direct lubricant away from the interface between the housing and the shaft. The housing is constructed as a spherical segment seated in a spherical seat to allow pivoting of the inner housing portion to pivot to adjust for misalignement.
