With a rated maximum load of 16.0 kg with a deflection of 1.6 mm, the 25 x 20 mm male-male bobbin mount in 45 Shore A soft rubber is engineered to deliver maximum vibration isolation where compliance and movement under load matter most. The relatively high deflection characteristic of this soft grade makes it the preferred choice for lighter, compact, or sensitive equipment where lower-frequency isolation is the priority and restraint is secondary to attenuation. Constructed with rubber-to-metal bonded technology, this bobbin mount accepts M8 threaded studs (stud length 20 mm) on both faces, allowing straightforward inline installation without additional hardware. The soft 45 Shore A compound provides greater deflection than harder grades of the same geometry, absorbing low-amplitude vibration energy more effectively and protecting sensitive instruments, lightweight panels, and fragile surrounding structures from transmitted shock. The mount may be loaded in shear, compression, or a combination of both, giving installation engineers flexibility in orientation. Typical applications drawn from the family source include instruments, air-conditioning units, and lighter industrial machinery and equipment. The rubber-to-metal bond improves machinery service life and enhances operator comfort in plant and mobile environments. Custom configurations in stainless steel metal components or oil-resistant and high-temperature rubber compounds are available on request. This mount is part of a broader range offered in alternative Shore hardness grades and overall dimensions. Companion variants at the same 25 x 20 mm body size include a 60 Shore A medium grade (2520MM20-60) and a 70 Shore A firm grade (2520MM20-70).

A. This mount has a maximum load rating of 16.0 kg and a deflection of 1.6 mm. The 45 Shore A soft rubber compound provides greater deflection than harder grades of the same 25 x 20 mm geometry, which is the defining characteristic of its isolation performance.
A. The 2520MM20-45 uses an M8 male thread on both faces, with a stud length of 20 mm on each side. The overall body dimensions are 25 mm diameter by 20 mm height.
A. Softer grades give greater deflection under load and better vibration isolation at lower frequencies. The 45 Shore A grade is suited to lighter or sensitive equipment where maximum attenuation is the priority. Harder grades — such as the 60 Shore A or 70 Shore A variants in this size — carry higher loads with less movement and are more appropriate where restraint or stiffness is required.
A. The mount may be loaded in shear, compression, or a combination of both, giving installation engineers flexibility in orientation to suit the application.
A. Applications confirmed in the product family source include instruments, air-conditioning units, and lighter industrial machinery and equipment. The soft grade is particularly suited to compact or sensitive installations where vibration isolation takes precedence over load restraint.
A. Yes. Oil-resistant and high-temperature rubber compounds, as well as stainless steel metal components and additional or custom sizes, are available on request.
A. We accept all major credit and debit cards, along with PayPal.
A. Standard UK mainland delivery is 3–5 working days. Next-day delivery is available on most products and will appear as an option at checkout where eligible.
