Jergens 36101 Round Spring Locating Stop 0.375 in Stop Head

Product Description

The JERGENS 36101 is a round spring locating stop designed to precisely position workpieces on fixtures, jigs, and production tooling. The spring-loaded stop head retracts under load and returns to its set position, providing consistent, repeatable part location during machining or assembly operations. Key dimensions include a 0.375 inch stop head outside diameter, a 0.125 inch stroke length, and a compact body measuring 0.6875 inches long by 0.9375 inches wide. The unit weighs approximately 0.016 pounds. It is typically installed by tooling engineers, machinists, or fixture builders working in precision manufacturing environments.

This locating stop suits applications where repeatable part registration is required on machining fixtures, welding fixtures, assembly jigs, and similar workholding setups. The low-profile body and slotted mounting base allow for straightforward integration into custom fixture plates. An initial end force of 10 pounds and a mid-stroke end force of approximately 4.54 kilograms support controlled, consistent part seating across production cycles.

Key Features

• Spring-loaded round stop head retracts and returns for repeatable part location
• Stop head outside diameter of 0.375 inches for precise positional reference
• Stroke length of 0.125 inches accommodates part loading and release
• Zinc aluminum alloy body with steel stop head for durability in production environments
• Slotted mounting base with 0.35 inch slot length and 0.14 inch slot width for positional adjustment
• Low profile at 0.2188 inches base thickness and 13/32 inches overall height

Compatibility

Designed as a standard spring locating stop for integration into custom machining fixtures, assembly jigs, and workholding plates where a round-head spring stop with a 0.375 inch head diameter and slotted base mount is required.

Installation Notes

Installation is typically performed by tooling builders or machinists. Power down and lock out any associated machinery before mounting or adjusting fixture components. Secure the stop using appropriate fasteners through the mounting slots to allow for positional fine-tuning before final tightening. Verify stop head travel is unobstructed and that the spring returns freely before placing the fixture into service.
