Product Number: 2520MF20-70
Variations
Carrying up to 40 kg with a controlled deflection of just 1.6 mm, the 2520MF20-70 is a compact 25 x 20 mm male-female bobbin mount engineered for applications where firm restraint and minimal movement take priority over high isolation. The M8 male stud (d1: M8 x 20 mm) and M8 female thread (d2: M8) allow direct inline installation without additional hardware, making fitment straightforward on confined assemblies. Rated at 70 Shore A, this mount sits at the firmer end of the hardness range. As the family source confirms, harder grades carry higher load with less movement, a characteristic that makes this grade well suited to absorbing shock and impact rather than isolating fine vibration. The rubber-to-metal bonded construction transfers load reliably whilst protecting surrounding structures, improving machinery lifespan and operator comfort across the service life of the installation. The mount may be loaded in shear, compression, or a combination of both, offering flexibility in mounting orientation. Typical applications drawn from the product family include diesel engines, generator sets, exhaust mountings, and industrial machinery and equipment, environments where mass or intermittent impact demands a firm, controlled mount rather than a soft isolator. The 25 x 20 mm envelope suits lighter, compact installations within those categories where a smaller footprint is required alongside a firm 70 Shore A characteristic. This mount is available in additional Shore A grades within the 25 x 20 mm male-female family: 45 Shore A (2520MF20-45) and 60 Shore A (2520MF20-60).

A. The 2520MF20-70 has a maximum load rating of 40.0 kg and a deflection of 1.6 mm, reflecting the firm, high-restraint characteristic of the 70 Shore A rubber grade.
A. The male stud is M8 with a 20 mm stud length (d1: M8 x 20) and the female thread is also M8 (d2: M8), allowing direct inline installation on both faces.
A. The mount measures 25 mm diameter by 20 mm height (D x H: 25 x 20 mm), making it a compact format suited to confined or lightweight machinery installations.
A. According to the product family specification, harder rubber grades carry higher loads with less movement. The 70 Shore A grade is the correct choice where firm restraint, shock absorption, or minimal deflection under load is required, rather than maximum vibration isolation.
A. The mount may be loaded in shear, compression, or a combination of both, providing flexibility in mounting orientation and installation geometry.
A. The product family identifies applications including diesel engines, generator sets, exhaust mountings, air-conditioning units, instruments, and industrial machinery and equipment, across industries such as power generation, construction and off-highway, agriculture, marine, and automotive.
A. Yes — the same 25 x 20 mm M8 male-female bobbin is also available in 45 Shore A (2520MF20-45) and 60 Shore A (2520MF20-60) for installations requiring greater isolation or lower load capacity.
A. Yes — stainless steel metal components and oil-resistant or high-temperature rubber compounds are available on request, alongside additional and custom sizes.
