Product Number: 6550MF37-45
Variations
Engineered for applications where isolation performance takes priority over load restraint, this 65x50mm male-female bobbin mount (SKU 6550MF37-45) carries a maximum load of 88.0 kg with a deflection of 4.5 mm at 45 Shore A, a softness grade that allows generous movement under load to absorb vibration energy before it transfers to surrounding structures. The threaded configuration uses an M12 x 37 male stud (d1) and an M12 female thread (d2), offering straightforward installation into existing mounting points without special tooling. At 45 Shore A, this mount sits at the softer end of the hardness range, making it particularly well suited to lighter, compact or sensitive equipment where lower-frequency vibration isolation is the priority. Rubber-to-metal bonded construction ensures reliable adhesion between the elastomer and steel elements, while the geometry supports loading in shear, compression, or a combination of both, giving designers flexibility in how the mount is oriented within an assembly. The soft rubber compound delivers the greater deflection characteristic of this grade, actively decoupling the mounted equipment from its supporting structure. Typical applications include instrument mountings, air-conditioning units, light industrial machinery, and sensitive electronic or mechanical assemblies where transmitted vibration or shock could degrade performance or accelerate wear. The mount contributes to improved operator comfort and protects surrounding structures from fatigue damage. Industries served include power generation, marine, agricultural, automotive, and construction and off-highway sectors. For installations demanding oil-resistant or high-temperature rubber compounds, or stainless steel metal parts, custom variants are available on request.

A. The mount has an outer diameter and height of 65x50mm, an M12 x 37 male stud (d1), and an M12 female thread (d2). Maximum load rating is 88.0 kg with a deflection of 4.5 mm.
A. 45 Shore A places this mount at the softer end of the hardness range. Softer grades deliver greater deflection under load, providing better vibration isolation — particularly at lower frequencies. This makes the mount well suited to lighter, compact or sensitive equipment such as instruments, air-conditioning units, and light industrial machinery where isolation performance matters more than restraint.
A. The bobbin mount can be loaded in shear, compression, or a combination of both, giving flexibility in installation orientation depending on the application.
A. Source-confirmed applications include air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and industrial machinery. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. Yes. The same geometry is available in 60 Shore A (6550MF37-60) and 70 Shore A (6550MF37-70) for applications requiring a firmer mount with higher load capacity and reduced deflection.
A. Yes. Oil-resistant rubber, high-temperature rubber, stainless steel metal parts, and additional or custom sizes are available on request.
