MRC212SDeep Groove Ball Bearing – 60 mm Bore x 110 mm OD x 22 mm Wide, Open, CN Clearance

Product Description

What this part is: MRC 212S single-row deep groove ball bearing, 60 mm bore, 110 mm outside diameter, 22 mm wide, on the ISO 6212 envelope. Bore Diameter: 60 mm. Outside Diameter: 110 mm. Overall Width: 22 mm. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Cage Material: Pressed steel. Cage Type: Pressed, ball-guided. Bearing Material: Chrome steel. Internal Clearance: CN. Precision Class: ABEC 1 / P0. Series: MRC 200, ISO 62 medium section. Decoding the designation: 212 — the MRC 200 series at bore code 12, giving a 60 mm bore on the medium ISO 62 section. S — Conrad-assembly deep groove, the non-filling-notch construction, so the raceways are unbroken all the way round. No closure letter — open both faces. On MRC an F or FF would add one or two shields and a Z or ZZ one or two rubber seals. What these specs mean in practice: Dynamic Load Rating: 55,300 N. Static Load Rating: 36,000 N. The dynamic figure sets rating life under rotation; the static figure sets the load the raceways carry standing still or shock-loaded without permanent brinelling. The Conrad construction has continuous raceway shoulders on both rings, so the bearing takes thrust in either direction alongside its radial load. The filling-notch 212M on the same envelope trades that symmetry for a higher ball count. Internal Clearance: CN. Standard radial clearance, sized for an ordinary interference fit on the shaft and a normal-temperature housing. Cage Material: Pressed steel, ball-guided. Light, tolerant of grease and of the shock loading a general-purpose drive bearing sees. Quantity and configuration: Unit Quantity: 1 Pc. One individual bearing, open both faces, straight bore. Interchange guidance: The 6212 boundary envelope is an ISO standard, so the equivalents below share bore, outside diameter and width exactly and interchange in the same housing bore and shaft seat: SKF 6212, FAG 6212, NSK 6212, NTN 6212, Timken/Fafnir 212K, RHP 6212, Koyo 6212, SNR 6212 and Nachi 6212. MPN variants seen on the carton and in catalogues: 212S, 212-S, 212 S16, 6212.
