Rubber Insert for Couplings

Gumis rubber inserts for couplings are suitable for a wide range of transmission coupling applications. They are used in electric motors, hydraulic machinery, agitators, fans, conveyors, pumps, wood-turning equipment, milling machines, paper mills, crushers and compressors. Although the accurate alignment of the coupling is important, the high-quality rubber inserts are very effective at absorbing shock and vibration.
Our rubber inserts are reliable in resilience and elasticity; resistant to oil, hydraulic fluid and most chemicals; operating temperature ranges from - 40ºF to +212ºF (-40ºC to +100ºC). With a hardness of 80-90 Shore A, providing the best damping capability among elastomeric elements.


Increased damping capabilities by using a rubber material instead of hard plastic


Plastic inserts melt when exposed to higher temperatures and oils/chemicals. This cannot happen to Gumis made rubber inserts for couplings.


Longer life span, built for tough conditions and resistant to engine room conditions


In-house production and QA guarantee a quality product every time.
