Where maximum vibration isolation takes priority over load restraint, the 75x50mm male-male bobbin mount at 45 Shore A delivers the greatest deflection in this geometry's range, 4.4 mm under a maximum load of 143.0 kg. Making it the natural choice for lighter or sensitivity-critical equipment where isolating low-frequency vibration matters most. The M12 x 37 mm threaded studs on both faces allow direct bolt-through installation without additional hardware, and the rubber-to-metal bonded construction provides a secure, long-service assembly across its working life. The softer 45 Shore A rubber compound is the defining characteristic here: at this hardness, the mount yields more freely under dynamic loading than medium or firm grades, absorbing and dissipating vibration energy rather than transmitting it onward into surrounding structures or frames. This compliance makes the mount particularly well suited to instruments, air-conditioning units, and sensitive industrial equipment where structure-borne noise or transmitted shock would degrade performance or operator comfort. The mount may be loaded in shear, compression, or a combination of both, broadening its installation versatility. With an overall diameter of 75 mm and a height of 50 mm, this is an upper-range bobbin in the standard-load band, proportioned for moderate mainstream machinery mounting duties where the application demands genuine isolation performance rather than maximum stiffness. The family source confirms applicability across generator sets, exhaust mountings, diesel engines, and general industrial machinery and equipment. Industries served include power generation, agriculture, marine, automotive, and construction and off-highway sectors.

A. The mount has an outer diameter of 75 mm and a height of 50 mm. The threaded stud is M12 with a length of 37 mm. Maximum load is 143.0 kg and deflection at that load is 4.4 mm.
A. The 45 Shore A grade is the softest available in this geometry. Softer rubber yields greater deflection under load, which provides superior vibration isolation — particularly at lower frequencies. It is best suited to lighter or sensitivity-critical equipment where isolating vibration matters more than restricting movement. Harder grades (60 Shore A or 70 Shore A) carry higher loads with less deflection and suit applications where restraint is the priority.
A. The mount may be loaded in shear, compression, or a combination of both, giving flexibility to suit different installation geometries and dynamic load directions.
A. Source-confirmed applications include air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and general industrial machinery and equipment. Industries served include power generation, agriculture, marine, automotive, construction and off-highway, and railway and mass transit.
A. Yes. The same geometry is available in 60 Shore A (SKU 7550MM37-60) and 70 Shore A (SKU 7550MM37-70) for applications requiring higher load capacity or reduced deflection.
A. Yes. Stainless steel metal components and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
A. We accept returns within 30 days of purchase for items that are unused, undamaged, and in their original packaging.
