Engineered for maximum vibration isolation, this 75x40mm female-female bobbin mount with M12 threads and a 45 Shore A rubber grade is the softest option in the 75x40mm bobbin range, delivering the greatest deflection and most effective isolation where load restraint is secondary to smooth, sensitive vibration control. At a rated maximum load of 157.0 kg and a deflection of 3.4 mm, this mount is well matched to moderate general-machinery applications where isolating low-frequency vibration takes priority over rigid load retention. The rubber-to-metal bonded construction allows the mount to be used in shear, compression, or a combination of both, providing installation flexibility across a wide variety of equipment configurations. The soft 45 Shore A compound yields under load to absorb and dissipate vibrational energy efficiently, protecting surrounding structures and improving operator comfort. Custom variants with oil-resistant or high-temperature rubbers, as well as stainless steel metalwork, are available on request. Typical applications for this grade include air-conditioning units, instrument mountings, diesel engines, generator sets, industrial machinery and equipment, and exhaust mountings, sectors spanning agriculture, power generation, marine, automotive, and construction and off-highway environments where sensitive or lighter equipment benefits most from a compliant, high-isolation mounting solution. The 75x40mm M12 female-female bobbin is available in 60 Shore A (7540FF12-60) and 70 Shore A (7540FF12-70) for applications requiring greater load-bearing capacity and reduced deflection. Larger-diameter alternatives with M16 threads are also offered across the 100x100mm geometry (100100FF16). This mount is supplied as an individual unit.

A. This mount has a maximum load rating of 157.0 kg and a deflection of 3.4 mm, making it suitable for moderate general-machinery loads where vibration isolation is the primary requirement.
A. A 45 Shore A rating indicates a soft rubber compound. Softer grades yield greater deflection under load and deliver better vibration isolation, particularly at lower frequencies, making this grade the preferred choice for sensitive equipment and lighter-duty mounting where isolation performance matters more than load restraint.
A. This mount may be loaded in shear, compression, or a combination of both, providing flexibility to suit varied installation configurations across a wide range of equipment types.
A. Applications include air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and general industrial machinery and equipment. Industries served include agriculture, power generation, marine, automotive, and construction and off-highway environments.
A. Yes. Oil-resistant and high-temperature rubber compounds, as well as stainless steel metalwork, are available on request for applications with specific environmental or chemical requirements.
A. Yes. The same 75x40mm M12 female-female geometry is available in 60 Shore A (7540FF12-60) and 70 Shore A (7540FF12-70) for applications requiring higher load capacity and stiffer mounting characteristics.
