Product Number: 4040MF25-70
Variations
Rated at a maximum load of 76.0 kg with a controlled deflection of just 3.6 mm, the 4040MF25-70 is a 40 x 40 mm male-female bobbin mount engineered to hold firm under heavier loads, shock events, and applications where minimal movement is essential. The male thread is M10 x 25 mm and the female thread is M10, making this mount ready for direct bolt-in installation in either orientation. At 70 Shore A, this is the firmest grade in the 40 x 40 mm male-female bobbin range. Harder-compound rubber carries the highest load within its size band while limiting deflection, the combination of 76.0 kg capacity and 3.6 mm deflection reflects precisely that characteristic. The rubber-to-metal bonded construction keeps the elastomer securely anchored under sustained or intermittent shock loading, and the mount may be used in shear, compression, or a combination of both to suit the installation geometry. This grade is well suited to diesel engines, generator sets, industrial machinery, and exhaust mountings where the mounting point must resist movement and absorb impact rather than prioritise soft isolation. Across the industries served, construction and off-highway, power generation, marine, agriculture, railway and mass transit, automotive, and military and defence. The 70 Shore A rating is the appropriate choice when structural restraint and load-bearing reliability take precedence over maximum deflection. Stainless steel hardware and oil-resistant or high-temperature rubber compounds are available on request for demanding environments.

A. The 4040MF25-70 has a maximum load rating of 76.0 kg and a deflection of 3.6 mm at that load.
A. The male stud is M10 with a 25 mm shank length (d1 x L: M10 x 25) and the female thread is M10 (d2: M10).
A. The mount measures 40 mm in diameter and 40 mm in height (D x H: 40 x 40 mm).
A. A 70 Shore A compound carries the highest load in the 40 x 40 mm male-female range with the least deflection. It is the correct choice when the installation demands structural restraint, resistance to shock and impact, or where minimal movement of the mounted item is a design requirement. Softer grades such as 45 or 60 Shore A offer greater deflection and are better suited to lighter loads or vibration-sensitive equipment.
A. The mount may be loaded in shear, compression, or a combination of both, giving installation flexibility across different equipment configurations.
A. Typical applications include diesel engines, generator sets, industrial machinery, exhaust mountings, and air-conditioning units. Industries served include construction and off-highway, power generation, marine, agriculture, railway and mass transit, automotive, and military and defence.
A. Yes — stainless steel hardware and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
A. Related mounts in the range include 4040MF25-45, 4040MF25-60, 100100MF44, 10050MF44, 10055MF44, 10060MF44, 10075MF44, and 1008MF10.
