Linear Ball Bearing - EP25G-OP 25mm Open RST specify this via Configure CADLinear ball bearing, open, with a 25mm 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. ISO Metric Series Open shell for rail supported shafts Handles cantilevered loads better than plain bearings Temperature
