MRC 211MFF single-row deep groove ball bearing. Bearing type: Deep groove ball bearing. Bore: 55 mm. Outside Diameter: 100 mm. Overall Width: 21 mm. Closure Type: Steel shields, both faces. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Ball. Material: Chrome bearing steel. Unit Quantity: 1 Pc. GTIN: 097741004725. The envelope corresponds to an ISO 6211.
2 — MRC medium 200 dimension block, matching the ISO 62 series.
11 — bore code giving Bore: 55 mm.
FF — Closure Type: two steel shields, one on each face.
A deep groove ball bearing carries radial load together with moderate thrust in either direction, and runs faster for a given size than any other ball bearing type. Shields on both faces hold the factory grease charge in and keep swarf, dust and coarse contamination out, which is what makes this a sealed-for-life fit in electric motors, fans, gearboxes, pumps and conveyor idlers. Shields run with a small clearance rather than rubbing, so they cost far less friction and speed than contact rubber seals on the same envelope.
Unit Quantity: 1 Pc. One bearing, shielded both faces, straight bore.
Straight bore on an interference-fit shaft seat, outer ring located in a bored housing. The bearing takes thrust either way, so it works as a located or a free position depending on how the housing clamps the outer ring. Mounting force is applied through the ring being fitted rather than across the balls.
The 55 x 100 x 21 mm envelope is the ISO 6211 seat, so a shielded 6211 from any maker fits the same shaft and housing — SKF 6211-2Z, FAG 6211-2ZR and NSK 6211ZZ. An open 6211 or a 6211-2RS with contact rubber seals shares the same seats with a different closure.
