Product Number: 5040MM25-45
Sensitive installations and lighter equipment call for a mount that prioritises isolation above all else, and the 50x40mm Male-Male Bobbin Mount in 45 Shore A (SKU 5040MM25-45) is engineered precisely for that role. With a maximum load rating of 49.0 kg and a deflection of 3.5 mm, this soft-grade bobbin allows the rubber element to work through its greatest range of movement under operating conditions, delivering the level of vibration absorption that lower-frequency and load-sensitive applications demand. Rubber-to-metal bonded construction with M10 x 25 mm male studs at both ends ensures secure, repeatable fixing without welding or adhesive. The 45 Shore A compound is the softest grade in the 50x40mm family, making it the first choice where protecting instrumentation, compact machinery, or structurally sensitive surroundings from transmitted vibration and shock matters more than rigid restraint. The mount may be installed in shear, compression, or a combination of both, giving installation engineers flexibility in how load is introduced to the element. The anti-vibration bobbin family addresses a broad span of industries and equipment types, including air-conditioning units, instruments, diesel engines, generator sets, exhaust mountings, and general industrial machinery and equipment. The soft 45 Shore A grade is particularly suited to applications in the lighter portion of that load range, where minimising transmitted force to surrounding structures and improving operator comfort takes priority. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for duty-specific requirements.

A. This mount carries a maximum load of 49.0 kg and has a deflection of 3.5 mm under load, reflecting the greater movement available from the soft 45 Shore A rubber compound.
A. Shore A hardness indicates the relative stiffness of the rubber element. At 45 Shore A this is the softest grade in the 50x40mm family, giving the greatest deflection and the highest degree of vibration isolation — best suited to lighter loads and applications where minimising transmitted vibration to surrounding structures is the primary objective.
A. The mount body is 50 mm diameter by 40 mm height, with M10 x 25 mm male threaded studs at both ends.
A. The mount may be loaded in shear, compression, or a combination of both, providing flexibility to suit different installation geometries and mounting arrangements.
A. Source applications include air-conditioning units, instruments, diesel engines, generator sets, exhaust mountings, and general industrial machinery. The 45 Shore A grade is particularly appropriate for lighter, compact, or sensitive installations where vibration isolation performance takes priority over load-bearing capacity.
A. Yes — the 50x40mm M10 x 25 male-male bobbin is also available in 60 Shore A (SKU 5040MM25-60) and 70 Shore A (SKU 5040MM25-70). Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request.
