Hyatt 5208Z Double Row Angular Contact Ball Bearing, Single Metal Shield, 40mm ID x 80mm OD x 30.2mm

This is a 5208Z double row angular contact ball bearing packaged under the Hyatt name by General Bearing Corporation. The 5208 designation is an interchangeable industry size used by many bearing makers, so the part crosses to other 5208 bearings with the same closure.

A double row angular contact bearing has two rows of balls set at opposing contact angles, similar in function to a back to back pair of single row angular contact bearings. That arrangement lets one bearing carry radial load, thrust load in both directions and moment load, while taking less axial space than a matched pair. In the part number, the 52 prefix identifies the double row angular contact light series, 08 gives the 40 mm bore, and the Z suffix indicates one metal shield. Boundary dimensions for the 5208 size are 40 mm bore, 80 mm outside diameter and 30.2 mm width.

Bearings of this size are used in pumps, gearboxes and other compact machinery, and are replaced by maintenance mechanics and repair shops during rebuilds.

Available from King Surplus inventory in Del Rio, Texas.
