Vlier SS88C Tangless Square Spring Locating Stop

Product Description

The VLIER SS88C is a tangless square spring locating stop designed to index, position, and retain components in precision assembly and fixturing applications. The tangless design eliminates the protruding tang common to standard spring stops, reducing interference in close-tolerance installations. The body measures 0.875 inches wide by 0.688 inches long with a stroke length of 0.125 inches. The stop head measures 0.625 inches wide by 0.625 inches tall and 0.187 inches thick. Force progression runs from 5.13 pounds initial end force through 10 pounds mid end force to 14.9 pounds final end force, giving technicians a predictable, progressive engagement feel. The body is machined from aluminum, keeping weight minimal at 0.03 pounds.

The SS88C is used in tooling, jig and fixture work, machine assembly, and production equipment where repeatable part location is required. The tangless square profile suits applications where a standard spring plunger or round-head stop would create interference or insufficient bearing surface. Machinists, toolmakers, and assembly technicians working in light manufacturing environments are the primary installers. The square stop head provides a flat contact face useful for registering flat-sided workpieces or fixture plates.

• Mounting slot dimensions of 0.136 inches length by 0.136 inches width for positive fastening

Compatibility

Designed as an OEM-style replacement or direct-install locating stop for tooling, fixtures, and precision assembly equipment requiring a tangless square spring stop with 0.875 inch body width and 0.688 inch body length.

Installation Notes

Installation is typically performed by toolmakers or assembly technicians. Power down or de-energize any equipment before servicing fixtures containing spring stops. Use the mounting slot dimensions and hole center spacing of 0.656 inches to align the stop accurately before fastening. Do not over-compress the stop head beyond its rated 0.125 inch stroke during assembly, as this can reduce spring performance and service life.
