Self-aligning roller thrust bearing for use with radial swivel-joint roller bearing in bearing unit for e.g. heavy load applications, has housing disk comprising front side with coating, where coating is not formed on housing disk path

摘要

The bearing (2) has a shaft disk (8), a housing disk (3) and roller bodies (9) arranged between the shaft and housing disks. The roller bodies roll on a shaft disk path (12) and a housing disk path (11) around a bearing axis (10). A front side of the housing disk axially limiting the bearing has a friction-reducing coating, where the coating is not formed on the housing disk path. The coating is made from PTFE, zinc phosphate, manganese phosphate or chromium. The front side is formed by an annular flat surface.
