Rubber Bumpers & Buffer Stops

Impact-absorbing bumpers and buffer stops for stroke ends, limit stops and door frames.

Overview

Bumpers and buffer stops absorb kinetic energy from moving parts during collision: solid or hollow cylinders, blocks or pads installed at stroke ends, limit stops or door frames. The elastic deformation of rubber converts impact energy into heat and dissipates it slowly, protecting equipment from hard-impact damage. Rubbrother offers various profiles and hardnesses, including ultra-soft 15A foam grades.

Key Features

  • High energy absorption via material internal friction and structural deformation
  • Excellent self-recovery after repeated impacts
  • Abrasion-resistant surface for long life under frequent collision
  • Tunable damping with hollow or honeycomb designs
  • Optional metal inserts for bolt-on mounting

Applications

  • Automation: air-cylinder stroke-end damping, slide limit protection
  • Logistics: shuttle carts and AGV anti-collision blocks
  • Elevators & cranes: car buffers, hook limit cushions
  • Automotive: door limit stops, tailgate buffers, suspension bump stops
  • Furniture hardware: cabinet door silencers, drawer bumpers
