Vlier SS90A Tang Square Spring Locating Stop

Product Description

The VLIER SS90A is a tang square spring locating stop designed for precision positioning applications in mechanical assemblies. Built with an aluminum body measuring 1.5 inches wide by 1 inch long, this spring stop delivers a 3/16 inch stroke length with a progressive force profile: 2 pounds initial end force, 14 pounds middle end force, and 25.9 pounds final end force. The tang profile and square stop head allow repeatable part location and controlled detent action. Machinists, toolmakers, and assembly technicians install this type of component in jigs, fixtures, and automated assembly equipment where consistent part positioning is required.

The SS90A is suited for light-duty to medium-duty fixture and tooling applications. The mounting slot configuration accepts standard fastener hardware, with slot dimensions of 3/16 inch length by 0.203 inch width. The 1-1/8 inch distance between mounting hole centers and 0.938 inch distance between mounting hole and edge allow straightforward integration into existing fixture plates or tooling blocks. The stop head measures 0.875 inch wide by 0.875 inch high with a 0.25 inch thickness, providing a defined contact surface for repeatable workpiece registration.

Key Features

• Progressive spring force: 2 lb initial, 14 lb middle, and 25.9 lb final end force for controlled detent engagement
• Tang profile provides positive rotational and lateral location of stop head
• Aluminum body construction for lightweight installation in fixture and tooling applications
• 3/16 inch stroke length suitable for short-travel positioning tasks
• Mounting slots sized at 0.203 inch width for standard fastener compatibility
• Compact 1.5 inch body width keeps fixture footprint minimal

Compatibility

Designed as an OEM-style replacement or direct-fit component for fixture plates, tooling jigs, and mechanical assemblies requiring a tang square spring locating stop with a 1.5 inch body width and 1 inch body length.

Installation Notes

Installation is typically performed by toolmakers or mechanical assemblers using standard hand tools and fasteners appropriate to the mounting slot dimensions. Ensure the mating fixture surface is clean and flat before securing the stop to prevent misalignment under load. Follow applicable machine safety lockout and tagout procedures before installing or removing spring stops in powered equipment. Do not exceed the rated final end force when compressing the stop, as overloading can deform the spring mechanism.
