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
