Product Number: 4020MF25-60
Variations
Sized at 40 x 20 mm with M10 x 25 male and M10 female threads, the 4020MF25-60 is a male-female anti-vibration bobbin mount rated to a maximum load of 79.0 kg and a deflection of 1.6 mm at 60 Shore A hardness, a medium grade that delivers a practical balance of load support and vibration isolation suited to the broad middle ground of machinery mounting. At 60 Shore A, this mount sits in the mid-range of the bobbin hardness scale, where rubber stiffness is firm enough to bear meaningful loads yet compliant enough to attenuate vibration and shock effectively. The rubber-to-metal bonded construction is built to withstand service in shear, compression, or a combination of both, making it adaptable across a range of installation orientations. Medium hardness grades carry higher loads with less movement than softer grades, providing a stable mounting platform while still improving operator comfort and protecting surrounding structures from transmitted shock. With a 40 mm diameter and 20 mm height, this is a compact mount well suited to lighter compact or sensitive installations where space envelopes are tight and applied loads fall within the sub-80 kg range per mounting. The male-female (Type A / Type 1) thread configuration integrates directly into machine frames and base plates without additional hardware. Typical applications drawn from the product family include air-conditioning units, exhaust mountings, instruments, industrial machinery and equipment, and generator sets across industries such as power generation, marine, automotive, and agriculture.

A. The mount has a body diameter of 40 mm and a height of 20 mm. The male stud is M10 x 25 mm and the female thread is M10. Maximum load is 79.0 kg per mounting, with a deflection of 1.6 mm at 60 Shore A hardness.
A. It uses a male-female (Type A / Type 1) configuration with an M10 x 25 mm male stud on one face and an M10 female thread on the other, allowing direct integration into machine frames or base plates.
A. The 4020MF25-60 may be loaded in shear, compression, or a combination of both, giving flexibility in how it is orientated within an installation.
A. At 60 Shore A, this is a medium-grade mount. Medium hardness carries higher loads with less movement than softer grades, making it suited to the broad middle ground of machinery mounting where both load support and vibration attenuation are required.
A. The product family lists air-conditioning units, exhaust mountings, instruments, industrial machinery and equipment, and generator sets as typical applications, across industries including power generation, marine, automotive, and agriculture.
A. Yes. The 4020MF25-45 offers a softer 45 Shore A grade for greater deflection and improved isolation at lower loads, and the 4020MF25-70 provides a harder 70 Shore A grade for higher-load or high-shock applications.
A. Stainless steel metals and oil-resistant or high-temperature rubbers, as well as additional and custom sizes, are available on request.
