MRC 5211M double-row angular contact ball bearing in the filling-notch maximum-capacity execution, open on both faces. Bore Diameter: 55 mm. Outside Diameter: 100 mm. Overall Width: 33.34 mm (1-5/16 in). Total Width: 33.34 mm. Contact Angle: 30°. Number Of Rows: 2. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Internal Clearance: CN. Design Units: Metric. Series: 5200. Base Number: 5211. Part Number: 5211M. Unit Quantity: 1 Pc.
5211 — MRC 5200 series double-row angular contact ball bearing, 55 mm bore.
M — filling-notch maximum-capacity construction.
Number Of Rows: 2. Contact Angle: 30°. Two rows of balls on a 30° angle carry radial load together with thrust in both directions from a single bearing position, so one seat locates the shaft axially both ways.
The filling notch admits extra balls into each row during assembly, which raises radial load capacity above the plain construction on the same envelope. A 30° angle puts more of the load path along the bearing axis than a 15° or 25° execution, so thrust capacity is higher and limiting speed lower.
Internal Clearance: CN. Standard radial internal clearance, set for a normal interference fit on the shaft and a normal running temperature.
Shaft seat 55 mm, straight bore. Housing bore 100 mm. Ring width 33.34 mm (1-5/16 in). Both faces are open, so the bearing takes lubricant from the housing cavity.
Unit Quantity: 1 Pc. One complete double-row bearing — rings, both ball rows and cage in a single assembly.
The filling-notch execution is its own construction and is identified by the M in the designation, which is why no ISO cross-reference is published against it: a plain 3211 is a different ball complement on the same envelope and is a related size rather than an interchange. Searchable forms of the number: 5211M, 5211-M, 5211 M, 3211.
