Locking Mechanism (e.g., set screw, clamp): Thread Size M4-M12

Component Specifications

Definition

A precision locking mechanism designed to fix the position of stroke limiters on linear or rotary motion systems. It prevents unintended movement during operation by applying controlled clamping force through mechanical means such as set screws, clamps, or wedges. These components ensure repeatable positioning accuracy and operational safety in automated equipment.

Working Principle

Works by applying radial or axial clamping force against the stroke limiter's adjustment shaft or housing. Set screws use threaded pressure points, while clamps employ lever-actuated compression. Both create friction or mechanical interference that prevents slippage under operational loads.

Materials

Typically hardened steel (AISI 4140/4340), stainless steel (304/316), or alloy steel with corrosion-resistant coatings. Set screws often use alloy steel with black oxide finish; clamps may incorporate bronze bushings or polymer inserts.

Frequently Asked Questions

What is the difference between set screw and clamp-type locking mechanisms?

Set screws apply localized pressure through threaded points, while clamps distribute force over larger surface areas. Clamps offer quicker adjustment but may require more space.

How often should locking mechanisms be inspected?

Monthly visual inspections and torque verification every 6 months or 2,000 operating hours, whichever comes first.
