| | Nov 10, 2009 — Combining secure workholding with excellent protection for finished surfaces, particularly in assembly, machining, inspection or repair operations, the Sof-Top Urethane Grippers are now available from Fixtureworks® (Fraser, MI), a leading North American manufacturer and supplier of workholding technologies and machine tool components.
The non-marking, non-staining Sof-Top grippers feature a bubbled urethane surface that provides for superior 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).
Sof-Top grippers are available in several sizes and mounting configurations to meet a wide array of application needs. 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. A Viton O-ring holds the ball in place while keeping contaminants out and providing smooth ball movement. The housing is made from a smooth alloy steel, heat treated to Rc 43/46 with a black oxide finish and is tapped for backside fastening.
The thrust screw assembly configuration, available in sizes from 3/8” to 5/16” (10-24 mm), allows straight-line static load thrust without transmitting torsional or radial force to the contact area. The free-floating ball design allows the thrust screw to continue to rotate while the ball remains stationary against the contact surface. This configuration is ideal for irregular shaped or contoured applications. The housing is made from alloy steel, heat treated to RC 43/46 with a black oxide finish. | |
