Where vibration isolation takes priority over load restraint, the 7550FF12-45 female-female bobbin mount delivers through its 45 Shore A rubber compound, the softest grade available in this 75 x 50 mm, M12 geometry. At this hardness, the mount achieves a maximum deflection of 4.4 mm under its rated load of 150 kg, offering the greatest compliance in the range and making it the natural choice wherever absorbing movement and protecting sensitive equipment matters more than limiting travel. Rubber-to-metal bonded construction gives the mount structural integrity across shear, compression, and combined loading orientations without reliance on mechanical fasteners alone. The female-female thread configuration, m12 on both faces. Simplifies installation between male-studded structures, while the 75 mm diameter and 50 mm height provide a stable footprint suited to the moderate load band this SKU occupies. Softer Shore A compounds are specifically characterised by greater deflection under load and improved isolation efficiency at lower frequencies, properties that directly benefit instruments, precision machinery, and equipment where transmitted vibration would otherwise compromise function or operator comfort. Typical applications served by this grade include air-conditioning units, exhaust mountings, diesel engine installations, generator sets, and general industrial machinery and equipment across sectors such as agriculture, power generation, marine, automotive, and construction and off-highway. Where the operating load is within range but low-frequency isolation or protection of surrounding structures is the primary concern, the 45 Shore A compound is the appropriate selection over harder grades in this family.

A. This mount carries a maximum load of 150 kg and achieves a deflection of 4.4 mm at that load. The 4.4 mm deflection is the greatest in the 75 x 50 mm M12 family, reflecting the compliance delivered by the 45 Shore A compound.
A. The 7550FF12-45 uses a female-female thread configuration with M12 threads on both faces, allowing direct mounting between two male-studded structures.
A. Shore A 45 is the softest grade in this family. Softer rubber compounds produce greater deflection under load and improve isolation efficiency at lower frequencies, making this grade best suited to lighter or sensitive equipment where absorbing vibration and protecting surrounding structures is the primary objective rather than limiting movement.
A. The 7550FF12-45 may be loaded in shear, compression, or a combination of both, giving flexibility in how it is oriented within an installation.
A. Applications include air-conditioning units, exhaust mountings, diesel engine installations, generator sets, instruments, and general industrial machinery and equipment across sectors such as agriculture, power generation, marine, automotive, and construction and off-highway.
A. Yes. The 75 x 50 mm M12 geometry is also available in 60 Shore A (7550FF12-60) and 70 Shore A (7550FF12-70). Larger 100 mm diameter M16 variants are available in multiple heights — 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 on request for applications requiring enhanced corrosion or temperature resistance.
