Guide Roller Generation GN 753.1


Achieving smooth and dynamic movements, the guide roller generation GN 753.1 has a special deep groove ball bearing of hardened roller bearing steel. They are available in six sizes, from 0.866 to 1.969 in. (22 to 50 mm) outer diameter. The bearing is covered on both sides by metal disks as it features permanent lubrication and a typical 2Z seal to protect against dust and dirt.


The outer race of the ball bearing is embedded in the POM plastic of the guide roller during the molding process. Each roller is machined to precise dimensions for an exact runout, making cylindrical and convex shaping of the running surface possible. Convex rolling surfaces compensate for alignment errors by preventing them from running on corners or edges.


The rollers can fasten via the smooth bore of the inner bearing race using a typical socket cap, shoulder screws or through a permanently riveted bearing pin, designed either with male or female thread. Both types of bearing pins are fitted with Torx drives to ensure optimal transfer of the tightening torque.
