Product Number: 3040MM20-70
Variations
Compact yet firm, the 3040MM20-70 is a male-male bobbin anti-vibration mount rated to a maximum load of 36.0 kg with a controlled deflection of just 3.6 mm, figures that reflect its 70 Shore A rubber and its purpose in holding components steady under heavier loading and impact. At 30 mm diameter by 40 mm height with M8 x 20 mm studded threads at both ends, it suits installations where movement must be minimised and the mounted item held firmly in position. The rubber-to-metal bonded construction allows the mount to be used in shear, compression, or a combination of both, giving flexibility in how it is fitted within an assembly. The 70 Shore A hardness grade is suited to applications carrying higher loads or subject to shock and impact, where a softer grade would deflect excessively. Alongside its load-bearing role, it contributes to improved machinery lifespan, reduced stress on surrounding structures, and better operator comfort. Typical applications include diesel engines, generator sets, industrial machinery and equipment, exhaust mountings, and air-conditioning units. The male-male thread configuration makes it straightforward to install between two threaded surfaces without additional adaptors. For specialist requirements, stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request, along with custom sizes. This mount is part of a wider range of male-male bobbin sizes and Shore grades. Softer and mid-grade variants in this 30 x 40 mm body are available as 3040MM20-45 and 3040MM20-60.

A. The mount has a body diameter and height of 30 x 40 mm, M8 x 20 mm male threads at both ends, a maximum load rating of 36.0 kg, and a deflection of 3.6 mm. The rubber hardness is 70 Shore A.
A. Shore A hardness indicates the firmness of the rubber element. At 70 Shore A, this is the firmest grade in the 30 x 40 mm male-male bobbin range. Harder grades carry higher loads with less movement, making them appropriate where the mounted component must be held firmly and deflection kept to a minimum.
A. The male-male bobbin family is suited to diesel engines, generator sets, industrial machinery and equipment, exhaust mountings, and air-conditioning units, among others. The 70 Shore A grade is particularly suited to heavier-load and shock or impact applications within these categories.
A. This mount may be loaded in shear, compression, or a combination of both, according to the installation requirements.
A. Yes. Softer and mid-grade options in the same 30 x 40 mm body are available as 3040MM20-45 (softer grade) and 3040MM20-60 (medium grade). Other body sizes in the range include 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44, and 10055MM44.
