Rubber Bushes
High-precision compression and transfer molded rubber bushings engineered for mechanical pivot joints, automotive suspensions, and industrial linkages. Accommodates angular misalignment and torsional oscillation while damping high-frequency dynamic vibrations.
Types & Configurations of Rubber Bushes
Flanged Cylindrical Rubber Bushings
Integrated end flange carrying thrust forces in automotive control arms and steering linkages.
Straight Sleeve Rubber Bushes
Smooth cylindrical elastomer bushings press-fitted into stamped metal housings.
Pre-Stressed Suspension Bushes
Rubber bushings assembled under pre-compression for maximum fatigue life in truck leaf springs.
Heavy-Duty Torsional Articulation Bushes
Engineered for off-highway earthmovers and tractors with high angular rotation.
Vibration Damping Motor Mount Bushes
High-loss factor elastomer isolating electric motor vibration in machinery frames.
