Product Number: 4040MF20-70
Variations
Firm rubber-to-metal bonded construction defines the 4040MF20-70, a male-female bobbin anti-vibration mount sized 40 x 40 mm with M8 x 20 male stud and M8 female thread, rated at 70 Shore A hardness, the highest load-bearing grade in this 40 x 40 mm family, engineered to restrain heavy equipment and absorb shock and impact where secure, controlled movement is the priority. With a maximum load capacity of 76.0 kg and a deflection of just 3.6 mm, this mount is the right choice when the application demands that the mounted item is held firmly in place with minimum compliance under load. The 70 Shore A rubber compound delivers the load retention and impact resistance suited to demanding industrial environments. Rubber-to-metal bonded construction ensures structural integrity across mounting cycles, and the male-female thread configuration allows secure in-line fitment, the M8 x 20 male stud threads into the supporting structure while the M8 female receives the equipment bolt directly. At this hardness grade, deflection is deliberately limited, making the mount appropriate wherever looseness, rocking, or excessive movement cannot be tolerated. Custom variants in stainless steel and oil-resistant or high-temperature rubbers are available on request for specialist environments. Typical applications for this firm-grade mount include generator sets, diesel engine installations, heavy industrial machinery, and construction and off-highway equipment where shock loads and sustained higher forces require a robust mounting solution.

A. The mount has an outer diameter and height of 40 x 40 mm. The male stud is M8 x 20 and the female thread is M8.
A. The 4040MF20-70 has a maximum load capacity of 76.0 kg and a deflection of 3.6 mm at that load. The 70 Shore A hardness grade gives the highest load retention and least movement of the 40 x 40 mm male-female range.
A. The firm 70 Shore A grade is suited to heavier loads and applications where shock, impact, or sustained force must be resisted with minimal movement — such as generator sets, diesel engines, heavy industrial machinery, and construction or off-highway equipment.
A. Yes. The mount may be loaded in shear, compression, or a combination of both, making it adaptable across a wide range of mounting configurations.
A. Yes. The same geometry is offered in 45 Shore A (4040MF20-45) for lighter, more sensitive installations and in 60 Shore A (4040MF20-60) for general-purpose use. Select the grade that matches the load and isolation requirements of your application.
A. Stainless steel metal components and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
