Triangular Three-Bolt Flanges for Standard Ball Bearing Units

btn-3d-download

These triangular three bolt flangettes are dimensionally the same as our standard 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 accommodates an industry standard metric spherical OD ball bearing. A frame opening is required for installation as the unit protrudes thru the frame, plate, or panel on which it is installed. The triangular flanges listed below are standard and are dimensionally the same as supplied by the leading ball bearing manufacturers.
