Product Number: 7555FF12-45
Variations
Where maximum vibration isolation takes priority over load restraint, the 75x55mm female-female bobbin mount in 45 Shore A rubber, sKU 7555FF12-45. Delivers the greatest deflection in its geometry group, with a rated maximum load of 130.0 kg and a deflection of 4.9 mm. That combination makes this the grade to reach for when the goal is absorbing low-frequency vibration from lighter or dynamically sensitive equipment rather than rigidly restraining heavier plant. Constructed with rubber-to-metal bonded technology, this bobbin accepts M12 female threads at both ends and can be deployed in shear, compression, or a combined loading mode. The soft 45 Shore A compound yields more freely under load than harder grades, which is precisely what allows it to attenuate vibration at the lower end of the frequency spectrum, protecting both the mounted equipment and the surrounding structure. Operator comfort and extended machinery service life are the direct practical benefits. Typical installation contexts include instrument panels, exhaust mountings, air-conditioning units, and generator sets where isolating the transmitted vibration path is critical and the load per mounting point falls within the moderate band. The mount is equally at home across marine, agricultural, and light industrial applications where movement under load is the desired characteristic rather than a liability. Custom sizes and oil-resistant or high-temperature rubber compounds are available on request. This 45 Shore A variant sits alongside firmer options within the 75x55mm M12 family: a 60 Shore A mount (SKU 7555FF12-60) and a 70 Shore A mount (SKU 7555FF12-70).

A. This mount carries a maximum load of 130.0 kg per mounting point and has a rated deflection of 4.9 mm, making it the softest — and therefore most compliant — option in the 75x55mm M12 family.
A. Softer grades such as 45 Shore A yield more under load, which means they absorb and attenuate low-frequency vibration more effectively. If the priority is isolating sensitive or lighter equipment from vibration rather than restraining heavy plant, the softer compound is the correct choice.
A. The mount may be loaded in shear, compression, or a combination of both, providing installation flexibility across a wide range of mounting configurations.
A. Typical applications include air-conditioning units, exhaust mountings, generator sets, instruments, and industrial machinery. Industries served include construction, agriculture, power generation, marine, automotive, and railway and mass transit.
A. Both ends of the bobbin are M12 female threads, giving a female-female configuration with an overall body size of 75 mm diameter by 55 mm height.
A. Yes. The 75x55mm M12 female-female family also includes a 60 Shore A variant (SKU 7555FF12-60) and a 70 Shore A variant (SKU 7555FF12-70). Larger M16 bobbins in a range of dimensions are also available — see SKUs 100100FF16, 10040FF16, 10045FF16, 10050FF16, 10055FF16, and 10060FF16.
A. Yes — stainless steel metal components and oil-resistant or high-temperature rubber compounds are available, as are additional and custom sizes, on request.
A. We accept all major credit and debit cards, along with PayPal.
