Lighter loads and vibration-sensitive installations call for a mount that prioritises isolation over restraint, and the 40x45mm Male-Male Bobbin Mount in 45 Shore A delivers exactly that. Rated to a maximum load of 28.0 kg with a deflection of 4.1 mm, this SKU sits at the softer, more compliant end of the 40x45mm range, the grade of choice where maximum vibration absorption and freedom of movement under load matter most. The M10 x 25 mm male-male stud configuration allows straightforward in-line fitment between component and structure. Constructed using rubber-to-metal bonded technology, the mount may be loaded in shear, compression, or a combination of both, giving engineers flexibility in orientation without sacrificing performance. The soft 45 Shore A compound yields greater deflection than firmer grades, providing the higher isolation efficiency that lower-frequency and low-load applications demand. For installations where protecting sensitive instruments or compact equipment from transmitted vibration is the primary objective, this grade offers the most movement and therefore the strongest isolating effect within the 40x45mm family. Typical applications include instrumentation mounting, air-conditioning units, exhaust mountings, diesel engines, generator sets, and general industrial machinery and equipment. The family covers industries spanning agriculture, power generation, marine, automotive, construction and off-highway, and railway and mass transit. Stainless steel fittings and oil-resistant or high-temperature rubber compounds are available on request for demanding environments. For firmer grades in the same 40x45mm M10 x 25 geometry, see the 60 Shore A variant (4045MM25-60) and the 70 Shore A variant (4045MM25-70).

A. This mount has a maximum load rating of 28.0 kg and a deflection of 4.1 mm. These figures reflect the 45 Shore A soft rubber compound, which yields greater movement under load than firmer grades in the same 40x45mm family.
A. The mount uses an M10 x 25 mm male-male stud configuration on both ends, giving a straightforward in-line fixing suitable for a wide range of light and compact installations.
A. The mount may be loaded in shear, compression, or a combination of both, as is standard across the male-male bobbin family. This flexibility allows engineers to choose orientation based on the specific vibration and load path of the application.
A. The 45 Shore A compound is the softest grade in the 40x45mm range. Softer grades produce greater deflection and superior vibration isolation efficiency, particularly at lower frequencies and lighter loads. If your priority is maximum isolation for sensitive instruments or compact equipment rather than high load-carrying capacity or restraint, this is the appropriate grade. Firmer grades — 60 Shore A (4045MM25-60) and 70 Shore A (4045MM25-70) — carry higher loads with less movement.
A. The male-male bobbin family is suited to air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and general industrial machinery and equipment. The 45 Shore A soft grade is particularly well matched to instrumentation and lighter or vibration-sensitive installations where isolation efficiency is the primary requirement.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for applications requiring greater corrosion resistance or elevated operating temperatures.
