Vlier NSS88 Round Spring Locating Stop 0.875in Base

Product Description

The VLIER NSS88 is a round spring locating stop designed to provide repeatable, controlled positioning in mechanical assemblies and fixturing applications. The unit features a spring-loaded stop head with a 0.375-inch outside diameter and a stroke length of 0.125 inches. Spring end forces progress from 5.13 pounds initial to 10 pounds mid-stroke to 14.9 pounds at full compression, making it suitable for applications requiring consistent, graduated resistance. The body measures 0.688 inches in length by 0.875 inches in width, with a base thickness of 0.2188 inches. Installation is straightforward using the slotted mounting pattern. The NSS88 is installed by machinists, toolmakers, and fixture technicians.

The NSS88 is used in precision workholding fixtures, jigs, assembly tooling, and automated machinery where repeatable part location is required. Its compact footprint and slotted mounting base allow for positional adjustment during setup. The aluminum body and Delrin stop head construction keep weight low while maintaining durability in production environments. This part is suited for light-duty industrial and manufacturing applications where a controlled spring-out locating function is needed.

Key Features

• Stop head outside diameter of 0.375 inches for precise locating engagement
• Stroke length of 0.125 inches with graduated end forces: 5.13 lb initial, 10 lb mid, 14.9 lb final
• Aluminum body construction for lightweight, corrosion-resistant performance
• Delrin stop head for low-friction, wear-resistant contact surface
• Slotted mounting base (0.136 inches slot width and length) allows positional adjustment
• Compact body at 0.688 inches length by 0.875 inches width for space-constrained fixtures

Compatibility

Designed as a direct-mount spring locating stop for use in standard fixturing and workholding applications where a 0.875-inch base width and slotted mounting pattern are compatible with the mounting surface.

Installation Notes

Installation is performed by toolmakers or fixture technicians using standard hand tools. Secure the unit through the slotted base holes, which allow minor position adjustment before final tightening. Ensure the mounting surface is flat and clean to maintain proper spring alignment and stop function. Do not exceed the rated final end force of 14.9 pounds during assembly or operation.
