Linear Ball Bearing IPK20GW 1-1/4" ID Square Flanged End

Double linear ball bearing 1.25" ID square-flanged, end mount featuring a heat-treated alloy steel shell for durability. The double-size design is equivalent to two standard-sized linear ball bearings mounted back to back, with the square flange formed at the end of the extended shell for secure four-bolt mounting. A low coefficient of friction, recirculating hardened steel balls, and a molded polymer resin retainer support smooth, quiet, high-speed operation. Linear ball bearings excel in cantilevered applications because their rolling-element design handles overhung loads and offset drive forces without being constrained by the restrictive 2:1 binding rule that applies to plain bearings. Standard double seals provide added protection at no extra cost.
