Fafnir MUB3/4 insert ball bearing unit. Bore Diameter: 3/4 in (0.7500 in). Bore Type: Straight. Rolling Elements: Ball. Number Of Rows: 1. Bearing Material: Chrome steel. Design Units: Imperial. The outer surface is spherical, so the insert self-aligns inside its housing seat.
MU — the Fafnir replacement insert unit family for SA, SAD and SADD series pillow blocks.
B — the inch bore size code, 3/4 in.
Bore Diameter: 3/4 in. The insert clamps onto a plain 3/4 in shaft, so no shaft machining is needed.
Locking Method: Locking collar. The collar grips the shaft and carries the drive torque, which is what allows a commercial shaft tolerance to be used.
Closure Type: Shielded, with a snap ring on the outer ring. The shield keeps swarf and coarse contamination out of the ball track; the snap ring locates the insert axially in its housing.
Housing Style: Spherical outer surface. The spherical seat lets the insert take several degrees of static shaft misalignment during mounting.
Unit Quantity: 1 Pc. Insert unit with its locking collar, snap ring and shield. This is the rebuild part for an existing SA, SAD or SADD pillow block.
No cross-references are published for this number. The MU insert is a Fafnir housing-specific replacement rather than an ISO-numbered bearing, so an interchange has to be matched on the insert outside diameter and the housing series. Search on the MUB 3/4, MUB-3/4 and MU B 3/4 forms of the number.
