Decoding the designation

205 — MRC 200 series, 25 mm bore.

S — single-row deep groove ball bearing, Conrad assembly.

FF — two shields, one on each face. On MRC, F and FF are the shield codes and Z and ZZ are the rubber seal codes.

G — snap ring groove machined into the outside diameter of the outer ring, with the ring supplied.

What these specs mean in practice

Closure Type: Two metal shields. The shields run with a small clearance against the inner ring land rather than rubbing on it, so they hold grease in and keep coarse debris out without the drag a contact lip produces. Running torque and heat generation stay close to an open bearing while the grease charge is still retained for life.

Internal Clearance: CN. The designation carries no clearance suffix, so the bearing is built to normal radial internal clearance — the right choice for an ordinary interference fit on the shaft with a moderate temperature differential between the rings.

Cage Material: Pressed steel. Cage Type: Pressed ribbon. The ribbon cage holds ball spacing over the full speed range of a 62-series bearing and adds very little mass to the ball set.

Mounting data

Shaft seat 25 mm. Housing bore 52 mm. Ring width 15 mm — the standard ISO 6205 envelope, so the shaft and housing seats are the usual ones for that size. The snap ring seats in the groove in the outer ring outside diameter and locates the bearing axially in a plain through-bored housing, so the housing needs no shoulder machined into it.

Quantity and configuration

Unit Quantity: 1 Pc. One complete bearing with both shields and the snap ring fitted.
