Thrust cylindrical roller bearings utilize crowned cylindrical rolling elements. These are separated by a machined brass roller riding retainer (cage) which are contained within precision ground shaft and housing plates. These bearings are intended for axial loads (load parallel to the axis of rotation). They are designed as medium or heavy duty series. Either series is available in three configuration types including double acting, self aligning and the most widely used "single acting" variety. Depending on your preference, these bearings are available in a wide variety of sizes and options.
Features & Benefits
Precision Ground Shaft Plate
Bore is precision ground for a line to loose fit on shaft. The O.D. has a turned finish and is smaller than the housing plate's outside diameter. Shaft plates are manufactured to conform to ABMA size and tolerance specifications.
Matched Precision Ground Rollers
Rollers are manufactured from through hardened bearing grade steel. The surfaces are ground, superfinished, and matched to .0001". The ends of the rollers have a large machined radius designed to reduce friction between the roller and the retaining ring. The larger bearings use multiple rollers per pocket to minimize slippage.
Machined Brass Roller Riding Retainer
Rollway thrust bearing retainers are machined from centrifugal cast brass.
Precision Ground Housing Plate
O.D. is precision ground for a line to loose fit in housing bore. The I.D. has a turned finish and is larger that the shaft plate's inside diameter. Housing Plates are manufactured to conform to ABMA size and tolerance specifications.
Materials:
The plates and rollers are made from either through-hardened or carburizing grade steel with hardness to Rockwell (Rc) 58-63
Upon request we can manufacture these components from CEVM or VIMVAR grades of material and M-50 tool steel for high temperature applications.
