Jergens 36103 Round Spring Locating Stop 2in Base

Product Description

The JERGENS 36103 is a round spring locating stop designed for workholding and fixture applications in machining and manufacturing environments. It provides repeatable, spring-loaded positioning of workpieces or components, automatically retracting when a part is loaded and snapping into position to prevent movement during operations. The stop head measures 13/16 inches outside diameter with a 1/4 inch stroke length, and the unit delivers 32 pounds of initial end force. The body is constructed from zinc aluminum alloy with a steel stop element, combining corrosion resistance with durability in industrial settings. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This locating stop is suited for use in jigs, fixtures, and workholding plates where spring-actuated part location is required. It mounts to flat surfaces via slotted mounting holes, allowing fine positional adjustment before final fastening. The 2 inch base width and 1-1/2 inch mounting hole center spacing make it compatible with standard fixture plate layouts. Typical applications include CNC machining centers, manual milling setups, and dedicated assembly fixtures where consistent part registration is critical to dimensional accuracy.

Key Features

• 1/4 inch stroke length allows smooth workpiece loading and positive spring-return location
• 32 pound initial end force provides firm, repeatable positioning under typical machining loads
• 13/16 inch stop head outside diameter suits standard locating pocket layouts
• Zinc aluminum alloy body with steel stop for a balance of light weight and wear resistance
• Slotted mounting holes (0.69 inches long by 0.257 inches wide) allow fine positional adjustment
• Low-profile design with 7/8 inch overall height minimizes interference with workpiece geometry

Compatibility

Designed as an OEM-style replacement and standard-fit component for spring locating stop applications in industrial jigs and fixtures requiring a round-head style stop with a 2 inch base width mounting footprint.

Installation Notes

Installation is performed by toolmakers or fixture builders using standard hand tools. Power down or de-energize any associated equipment before installing or servicing workholding fixtures. Secure the mounting fasteners through the slotted holes and verify final position before fully tightening, as the slots allow lateral adjustment. Follow applicable shop safety procedures and fixture design standards when integrating locating stops into production tooling.
