Decoding the designation

7209: series 72, bore code 09, 45 mm bore, 85 mm outside diameter, 19 mm width. PDTDF 003 is the order-code portion of the marking and is carried as a manufacturer part-number variant, searchable in that form.

What these specs mean in practice

A 45 mm bore angular contact ball bearing in the 72 series is a spindle and gearbox size that carries combined radial and one-direction axial load. Bought as a matched set, the four rings are ground together, so the load shares evenly across the stack and the shaft holds its axial position.

Quantity and configuration

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.
