What these specs mean in practice:

Four pieces, 4 Pcs, a factory matched set.

Fitting notes:

Straight bore, open on both faces. Matched set pieces mount in the order and orientation marked on their faces, clamped between a shaft shoulder and a locknut with the outer rings seated square in the housing bore.
