JW Winco has expanded its guide roller offering to include the standard part GN 753.1. With its entirely new design, these guide rollers have 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) in outer diameter. The bearing features permanent lubrication and a typical 2Z seal with metal disks on either side 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, which makes 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.
The smallest roller option can accept dynamic radial loads of up to 400 N, while the largest roller rates for loads as high as 1,500 N. All rollers are designed for lifetime performance of 656,167 ft (200,000 m) and speeds of 1.3 ft/sec (0.4 m/sec).
