Linear ball bearing, open shelled, with a 20mm ID JIS Metric, featuring a standard-sized heat-treated alloy steel shell that enhances durability and load capacity. Recommended over plain bearings in cantilevered applications as the 2:1 binding rule does not apply. Double seals add protection, a low coefficient of friction enables higher speeds, and a resin retainer polymer cage reduces noise.
