Fafnir 3M212WI-MBR angular contact ball bearing with a machined bronze cage, supplied as a three-piece universally ground set. Bore Diameter: 60 mm. Outside Diameter: 110 mm. Overall Width: 22 mm. Contact Angle: 25°. Precision Class: ABEC 3 / P6. Cage Material: Bronze. Cage Type: Machined. Rolling Elements: Ball. Bearing Material: Bearing Steel. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1. Design Units: Metric. Series: 200WI. Base Number: 3M212WI.
3 — 25° contact angle on the Fafnir angular contact scheme.
212 — 200WI series, ISO 72-series envelope, 60 mm bore, giving the 7212 boundary dimensions.
WI — low shoulder on both rings.
MBR — machined bronze cage.
TRI — triple set, universally ground so the faces are flush.
Contact Angle: 25°. A 25° angle carries more thrust per row than a 15° execution on the same 60 x 110 x 22 mm envelope, and suits spindles where axial stiffness is the governing requirement.
Cage Material: Bronze. Cage Type: Machined. A machined bronze cage tolerates higher operating temperature and marginal lubrication than a polymer or phenolic cage, and holds its pocket geometry under thermal cycling. It is the execution reached for on hot spindles and on oil-mist and circulating-oil systems.
Precision Class: ABEC 3 / P6, from the carton designation.
Unit Quantity: 3 Pcs. The three bearings are universally ground, so the set can be stacked back-to-back (DB), face-to-face (DF) or in tandem (DT) to suit the load direction, and any two faces butt flush without shimming.
The MBR machined bronze cage is a Fafnir-specific execution, so the Fafnir number is the designation to specify: 3M212WI-MBR identifies the bronze-cage build exactly. Searchable forms: 3M212WIMBR, 3-M-212-WI-MBR, 3M212 WI MBR, 3M212WI MBR TRI.
