Double Linear Ball Bearing - Square Flanged JPK12GW 12mm JIS Metric, End Mount

Twin 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 for plain bearings. The double-size design is equivalent to two standard linear ball bearings mounted back to back, allowing it to handle more load. The square flange allows secure mounting to a machine frame or plate. For best performance, use in applications where routine maintenance and clean operating conditions can be maintained.
