Vlier NSS90 Round Spring Locating Stop 1x1.5in Body

Product Description

The VLIER NSS90 is a round spring locating stop designed to position and retain workpieces or components in manufacturing and assembly applications. It features a 0.562-inch stop head outside diameter with a 0.188-inch (3/16 inch) stroke length, providing controlled spring-loaded engagement across the full stroke range. The aluminum body measures 1 inch in length by 1.5 inches in width, with a 0.3125-inch base thickness. Spring force progresses from 2 pounds initial end force through 14 pounds mid-stroke to 25.9 pounds final end force, giving installers predictable, staged resistance suited to precise locating tasks.

The NSS90 is used in industrial fixture and tooling assemblies where repeatable spring-loaded positioning is required. Typical applications include jig fixtures, assembly line tooling, and machine tool setups in light manufacturing environments. The unit mounts via slotted holes with 1.125-inch center-to-center spacing and 0.875-inch hole-to-edge distance. Slot dimensions of 0.203 inches in both length and width allow for minor positional adjustment during installation. This part is installed by tooling engineers, machine builders, and maintenance technicians working with precision workholding equipment.

Key Features

• Spring-loaded stop head with 0.562-inch outside diameter for consistent workpiece engagement
• Progressive spring force: 2 pounds initial, 14 pounds mid-stroke, 25.9 pounds final end force
• 0.188-inch stroke length accommodates positional variation while maintaining firm location
• Aluminum body construction for light weight and corrosion resistance
• Derlin stop head material provides low-friction, wear-resistant contact surface
• Slotted mounting holes allow positional adjustment during installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial fixtures and tooling assemblies requiring a round spring locating stop with a 1.5-inch base width and 0.188-inch stroke.

Installation Notes

Installation is performed by tooling technicians or machine builders using standard hand tools. Power down and lock out any associated machinery before installing or servicing this stop. Secure mounting fasteners through the slotted holes to allow fine positional adjustment before final tightening. Do not exceed the rated final end force of 25.9 pounds during operation, as overloading the spring mechanism may cause premature wear or loss of locating accuracy.
