Motion limiter Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A precision mechanical component integrated into flexure bearing systems to physically constrain the range of motion, preventing over-travel and mechanical failure. It functions as a hard stop or adjustable limit mechanism that maintains bearing integrity under dynamic loading conditions.

Working Principle

Operates through mechanical interference or contact-based stopping mechanisms that engage when the flexure bearing reaches predetermined displacement limits. Utilizes either fixed physical stops or adjustable limit switches to interrupt motion transmission.

Materials

High-strength alloy steel (AISI 4140/4340), stainless steel (316L), or hardened tool steel with surface treatments (nitriding, chrome plating) for wear resistance.

Technical Parameters

Lifecycle >10^7 cycles
Travel Range ±0.5mm to ±5mm
Repeatability ±0.01mm
Shock Resistance 50g peak
Maximum Load Capacity 500N to 5000N
Operating Temperature -40°C to 120°C

Standards

ISO 10791-7, DIN 55189
