Jergens 36111 Tangless Square Spring Locating Stop

Product Description

The JERGENS 36111 is a tangless square spring locating stop designed for precision workpiece positioning in fixturing and tooling applications. The tangless design eliminates the protruding tang found on standard locating stops, reducing the risk of interference with workpieces or fixtures during loading and unloading. The body measures 1.5 inches wide by 1 inch long with a 3/16-inch stroke length. Spring force ranges from 14 pounds at mid-stroke to 32 pounds at both the initial and final end positions. The body is constructed from zinc aluminum alloy with a low carbon steel stop head. This component is installed by toolmakers, fixture builders, and machining professionals.

The JERGENS 36111 is suited for use in machine tool fixtures, jigs, and workholding setups where repeatable part location is required. The spring-loaded stop head retracts under load and returns to position, allowing parts to be seated and removed without manual adjustment. The 1-1/8-inch distance between mounting hole centers and the 0.54-inch by 0.2-inch mounting slots allow it to be secured into standard fixture plates and bases. It is commonly found in production machining environments handling repetitive part runs where consistent registration is critical.

Compatibility

Designed as a direct-fit locating stop for standard fixture plates and tooling bases requiring a tangless square spring stop with 1-1/8-inch mounting hole center spacing.

Installation Notes

Installation is typically performed by toolmakers or fixture engineers during fixture build or maintenance. Secure the stop using fasteners through the mounting slots before applying workpiece load. Ensure the fixture plate or base is de-energized and any clamping pressure is fully released before removing or replacing the stop. Do not exceed the rated spring force range by applying side loads or impacts directly to the stop head.
