Описание
• consist of a shaft washer, a housing washer and a ball and cage assembly.
• can accommodate axial loads and locate a shaft axially, in one direction only.
• The single direction thrust ball bearings are mainly used in situations where axial force is only applied in one direction. These situations include linear reciprocating motion mechanisms, screw transmission mechanisms, etc.
