CONNEX Spring Pins


Standard & Ground

CONNEX Heavy and Light Spring Pins have a distinct advantage among commonly used tension fastening and locating elements for the following reasons:

  • The CONNEX Principle offers design advantages over other spring pins.
  • Higher manufacturing precision results in close tolerances in diameter and length.
  • The toothed slot increases roundness, thus allowing use as axial pin and center pivots.
  • The roundness accomodates automatic feed, making CONNEX Pins suitable for assembly units.
  • The ground pin results in improved precision.

Ground CONNEX Spring Pins

Specific applications using the unique characteristics of the CONNEX Spring Pins allow innovated construction solutions. Some examples are:

  • When using several pins to connect two parts, the CONNEX Spring Pin takes care of the unavoidable minimum amount of error in distances between the center of the axes. This is feasible with plain pins, but more so with Ground CONNEX Spring Pins, in applications which require high precision.
  • In today's gear and vehicle industries, positioning problems must be solved under conditions of high frequency and vibrations, whereby both high precision and elasticity are required in the pin connection. A situation for which a CONNEX Spring pin is ideal.

Ground CONNEX Light Spring Pins also used as centering and positioning elements

  • The CONNEX Spring Pin is also suitable for hinge functions. Its closed shape protects the hinge bore. The bore diameter of the moving part is then determined by the diameter of the pin before insertion.

The Ground CONNEX Spring Pin

The Ground CONNEX Spring Pin can be described as a uniquely designed fastening and locating pin that provides options to engineers that are not offered with solid or regular spring pins.

Many sectors of vehicle, pump, machine tool, compressor and motor industries, along with others, require precise positioning of assembled parts. Even with the high precision of CNC controlled machinery, small deviations can occur in the center axes of the receiving bore in those parts. This causes problems during assembly.
