Construction
Instead of inner and outer rings there are two (or three) flat washers: a shaft washer on the shaft, a housing washer against the housing, with the ball and cage assembly between them.
Load capacity
Takes axial load only and no radial load at all — a separate bearing must carry the radial load. Single-direction types load one way, double-direction types (52xxx) both ways. Permissible speed is low.
