Sof-Top urethane grippers from Fairlane Products (distributed by Fixtureworks) are non-marking, non-staining and feature a bubbled urethane surface that provides non-slip grip. The “bubbled” texture of the urethane top offers firm holding and allows air to escape so no suction is created between the contact surface and the top of the rest pad as it is compressed. The urethane surface, which offers superior abrasion and wear resistance, is available in three durometers (strength ratings).
These grippers are available in several sizes and mounting configurations to meet an array of application needs—fixed gripper, replaceable swivel ball and thrust screw assembly. With the fixed gripper configuration, the urethane surface is permanently bonded to a 300 series stainless steel pad. They are blind-hole tapped for back side mounting and are offered in sizes ranging from 5/16” to 1” (8-25 mm). The replaceable swivel ball configuration, available in sizes from 3/8” to 5/16” (10-24 mm), features a cylindrical body that allows for installation in tight areas. The replaceable ball swivels to allow for self-alignment on uneven surfaces. The thrust screw assembly configuration, available in sizes from 3/8” to 5/16”, allows straight-line static load thrust without transmitting torsional or radial force to the contact area.
