Spring Stops

Spring stops are spring-loaded mechanical components that provide accurate, controlled end forces in workholding and fixture applications where fixture walls are not available. The aluminum body is offered with a steel nose or Delrin® nose. Delrin® nose models provide electrical insulating properties and help prevent marring on soft metals such as brass and aluminum. Available in three stroke sizes: 1/8, 3/16 and 1/4. Product not available in metric.

Specify by:

Nose material (steel or Delrin®)
Required stroke (1/8, 3/16 or 1/4)
End force requirement (initial, mid and final)
Part number series and envelope dimensions (A–Q per table)

Spring Stops

Vlier’s spring stops provide accurate, controlled end forces in a range of applications where fixture walls are not available. The spring-loaded stops have an aluminum body design, and feature the option of a steel or Delrin^® Nose, which has electrical insulating properties and prevents marring of soft metals such as brass and aluminum.
