Vlier SS88B Tangless Square Spring Locating Stop

Product Description

The VLIER SS88B is a tangless square spring locating stop designed to provide repeatable, spring-loaded positioning in precision assembly and machining applications. The aluminum body measures 0.875 inches wide by 0.688 inches long with a 0.125-inch stroke length. The stop head is 0.625 inches wide by 0.625 inches tall with a thickness of 0.1875 inches. The tangless design eliminates the protruding tang found on standard spring stops, reducing the risk of snagging or interference in tight fixture layouts. This part is installed by tool and die makers, fixture builders, and precision machinists working on jigs, fixtures, and assembly tooling.

The SS88B is suited for use in light-to-medium duty locating applications where a compact, low-profile stop is required. Its spring-loaded head delivers a progressive force range, starting at 5.13 pounds initial end force, building to 10 pounds at mid-stroke, and reaching 14.9 pounds final end force at full compression. This force progression makes it well matched to applications that require controlled resistance during part loading and seating in machined fixtures or assembly nests.

Key Features

• Tangless square profile eliminates interference common with tang-style stops in close-tolerance fixture layouts
• Progressive spring force: 5.13 lb initial, 10 lb mid, 14.9 lb final end force
• Compact body: 0.875 inches wide by 0.688 inches long
• 0.125-inch stroke length for controlled, short-travel actuation
• Mounting slot dimensions of 0.125 inches long by 0.136 inches wide for secure panel or plate mounting
• Aluminum body construction for lightweight, corrosion-resistant performance

Compatibility

Designed as an OEM-style replacement or direct-fit locating stop for precision jigs, fixtures, and assembly tooling 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 tool and die makers or fixture technicians using standard machining and fitting tools. Ensure the mounting surface is clean and flat before seating the stop, and confirm the mounting slot dimensions match the mating hardware. Depower or depressurize any associated fixture or automated system before servicing or replacing locating stops. Do not exceed the rated stroke length during installation, as overcompression can permanently damage the spring mechanism.
