BUSHES
Rubber bushes absorb shock and reduce noise and vibration between metal parts. They are used in suspension systems, engine mounts, and industrial machinery. Our bushes are made from high-durability elastomers to withstand heavy loads and environmental stresses. Bright Star offers cylindrical, flanged, and bonded bushes to meet specific mechanical performance requirements.
