Vlier SS90C Tangless Square Spring Locating Stop

Product Description

The VLIER SS90C is a tangless square spring locating stop designed for precision positioning applications in manufacturing and assembly fixtures. It features a 1.5-inch body width and 1-inch body length with a 3/16-inch (0.188-inch) stroke length. The spring-loaded stop head delivers a graduated end force profile: 2 lb initial, 14 lb mid, and 25.9 lb final end force, making it well-suited for repeatable workpiece location under varying clamp loads. The aluminum body keeps weight low while providing adequate rigidity for fixture use. Machinists, tool and die makers, and fixture builders are the primary installers of this component.

The SS90C is used in machine tool fixtures, assembly jigs, and production tooling where a low-profile, spring-actuated locating stop is required. The tangless design eliminates the need for a tang removal step during installation, simplifying setup. Mounting hole centers are spaced 1.125 inches apart, with a 0.938-inch distance between the mounting hole and the body edge, allowing integration into standard fixture plates and tooling blocks.

Key Features

• Tangless design simplifies installation by eliminating tang removal
• Graduated spring force: 2 lb initial, 14 lb mid, 25.9 lb final end force
• Aluminum body construction for lightweight, corrosion-resistant performance
• 0.188-inch stroke length accommodates workpiece variation in locating applications
• Mounting slot dimensions of 0.203-inch width and 0.203-inch length allow precise positioning on fixture plates
• Stop head dimensions of 0.875-inch height and 0.25-inch thickness provide a compact contact profile

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard spring locating stop applications in precision machining fixtures and assembly tooling.

Installation Notes

Installation is typically performed by machinists or toolmakers during fixture fabrication or maintenance. Power down and de-energize any associated automated equipment before servicing fixture components. Use appropriate torque practices for mounting fasteners per the fixture design specification. Verify that the mounting slot orientation and hole center spacing match the fixture plate layout before final assembly.
