LPST leveling mounts swivel 10-15° to all sides of the centerline to adjust to uneven surfaces used for leveling machine tools, electronic racks, benches, etc. Large diameter pad design assures solid support. Coupling nut is not recommended to use for installation. Use nut on tapped hole of 1 - 1 1/2 times the thread diameter being used. To insure proper leveling mount size, divide the machine weight by the number of mounts required. This will equal the pounds or load per mount. Maximum load ratings for leveling mounts with elastomer pad are based on a calculation of 40% distortion to the elastomer pad. This insures the proper application requirements when using the bore with the non-skid elastomer pad. For certain minimum quantities, modifications such as lag bolt holes and other versions of plating are available upon request. Heat resistance for Delrin base mounts: Continuous operating temperature--82°C (180°F); melting point--175°C (34°7F).
