Product Number: 4025MF20-70
Variations
Rated to a maximum load of 100 kg with a controlled deflection of just 2.1 mm, the 4025MF20-70 is a 40 x 25 mm male-female bobbin mount engineered for applications where firm restraint and minimal movement under load are the priority. The 70 Shore A rubber hardness places this mount at the harder end of the standard range, making it the appropriate choice when machinery must be held securely against heavier operating loads, shock forces, and impact rather than isolated from fine, low-amplitude vibration. Rubber-to-metal bonded construction provides a durable, integrated assembly. The male thread is M8 with a 20 mm stud length (d1 x L: M8 x 20) and the female thread is M8 (d2: M8), allowing straightforward installation into bracketed or tapped mounting arrangements. The mount may be loaded in shear, compression, or a combination of both, giving flexibility in how the load path is arranged within a structure. As with all grades in the family, this mount contributes to improved machinery lifespan and protects surrounding structures from transmitted shock. Typical applications for the 70 Shore A grade include diesel engines and generator sets operating under heavy cyclical loading, industrial machinery and equipment where positional stability is required, exhaust mountings subject to sustained heat and vibration, and off-highway or agricultural plant where shock and impact loading are routine. The firm grade suits industries including construction and off-highway, power generation, agriculture, marine, and automotive. Custom configurations in stainless steel or oil-resistant and high-temperature rubbers are available on request.

A. This mount has a maximum load capacity of 100 kg and a controlled deflection of 2.1 mm, reflecting its 70 Shore A rubber hardness and firm-grade characteristics.
A. The male stud is M8 with a 20 mm length (d1 x L: M8 x 20) and the female thread is M8 (d2: M8), enabling installation into a wide range of bracketed or tapped mounting arrangements.
A. A 70 Shore A rating places this mount at the firmer end of the standard range. Harder grades carry higher loads with less movement, making this grade suited to applications requiring firm restraint against heavier loads, shock forces, and impact rather than isolation of low-amplitude vibration.
A. The mount may be loaded in shear, compression, or a combination of both, providing flexibility in how the load path is arranged within the mounting structure.
A. Source applications include diesel engines, generator sets, industrial machinery and equipment, exhaust mountings, and off-highway and agricultural plant subject to shock and impact loading. Industries served include construction and off-highway, power generation, agriculture, marine, and automotive.
A. Yes. Stainless steel metals and oil-resistant or high-temperature rubbers, as well as additional and custom sizes, are available on request.
A. The same geometry is available in softer grades listed under SKUs 4025MF20-45 and 4025MF20-60. Larger male-female bobbin variants include 4030MF25-70, 5050MF25-70, 100100MF44, 10050MF44, 10055MF44, 10060MF44, 10075MF44, and 1008MF10.
