TIMKEN angular contact bearings

7200 B, 7201 B and 3201 A have four-digit bases, a space and a final letter. The first two retain a 72 base with B; the third retains a 32 base with A. No unvalidated contact angle or letter interpretation is published here. The catalog records 10 mm bore for 7200 B and 12 mm for 3201 A. Keep designation and dimensions separate: one identifies the reference, the others verify its seats.

In a pump or transmission head, the bearing may help locate the shaft axially with other components. An assembly view should show opposing parts, spacers and adjustment faces. Record position and orientation before placing removed bearings together. A machine-specific arrangement cannot be reconstructed simply by counting bearings left on the workbench.

Give MR Accesorios Industriales full code, quantity and equipment identity. State whether one part or a documented combination is needed, and photograph every marking. Add verified bore, outside diameter and width. Include manual adjustment requirements where present. Identify unreadable letters as uncertain rather than replacing them with a nearby reference's ending; an assumption must not become confirmed selection data.
