Triangular Three-Bolt Flanges for Standard Ball Bearing Units

These triangular steel stampings are the same as our round 40MM-3, 47MM-3, 52MM-3, 62MM-3 and 72MM-3 parts.   They are used where space is limited.   One housing unit consists of two identical self-aligning flanges.   Each pair of flanges has a spherical outer surface of the ball bearing ring to provide self-alignment in any direction.

A minimum of space is required for installation as the unit protrudes thru the frame, plate, or panel on which it is installed.

The flanges listed below are standard and are dimensionally the same as supplied by the leading ball bearing manufacturers.
