Self-aligning closed linear ball bearing with a 40mm ID (inner diameter). Featuring a heat-treated alloy steel shell for durability, a resin retainer polymer cage for reduced noise and a low coefficient of friction for speed. Handles cantilevered loads better than plain bearings, overcoming the 2:1 binding ratio limitation of plain bearings.
