which uses three hardened chrome steel roller bearings for precise motion

Double Linear Ball Bearing - Square Flanged JPK12GW 12mm JIS Metric, End Mount RST 1" OD and 1" lengthTwin linear ball bearing with JIS 12mm ID, square flanged end mount housing, heat treated alloy steel shell, quiet resin retainer polymer cage, and double seals included as standard. Built to Japanese Industrial Standards, the recirculating ball design provides low friction, high speed linear motion and can outperform plain bearings in cantilevered applications where overhung loads and offset drive forces may trigger the restrictive 2: 1 binding rule
