Vlier SS88A Tang Square Spring Locating Stop

Product Description

The VLIER SS88A is a tang square spring locating stop designed for precision positioning applications in industrial and mechanical assemblies. The unit features an aluminum body measuring 0.875 inches wide by 0.688 inches long, with a 1/8 inch stroke length that governs the range of motion. End force progresses from 5.13 pounds initial to 10 pounds mid-stroke to 14.9 pounds at final engagement, delivering controlled, repeatable locating force. The stop head measures 0.625 inches wide by 0.625 inches tall with a thickness of 0.187 inches. Mounting hole centers are spaced 0.656 inches apart, matching the distance from the mounting hole to the body edge. This part is installed by machine builders, tool and die technicians, and maintenance personnel working on fixtures and precision assemblies.

The SS88A is suited for use in fixture plates, tooling bodies, jigs, and production machinery where a compact, spring-loaded tang locating stop is required. The tang profile and square stop head facilitate consistent part registration and positive retention in tight spaces. Its aluminum construction keeps weight low while maintaining sufficient structural integrity for repeated cycling in light-to-medium industrial locating applications. The mounting slot measures 1/8 inch in length by 0.136 inches wide, and the base is 3/16 inch thick, allowing flush or near-flush installation into prepared mounting pockets.

Compatibility

Designed as an OEM-style spring locating stop for use in standard tooling plates, fixture bodies, and precision mechanical assemblies that accept tang-profile locating stops with matching mounting geometry.

Installation Notes

Installation is typically performed by toolmakers or machine maintenance technicians using standard milling and drilling equipment to prepare the mounting pocket. Power down and de-energize any associated machinery before servicing or replacing locating stops in automated fixtures. Ensure the mounting slot and pocket dimensions match the stop body before pressing or fastening into place. Do not exceed the rated stroke length, as overtravel can damage the internal spring mechanism.
