Rated at a maximum load of 73.0 kg with a controlled deflection of just 4.1 mm, the 4045MM25-70 is the firmest-grade option in the 40x45 mm male-male bobbin mount family, the mount to specify when the primary requirement is load-bearing capacity and minimal movement under stress. At 70 Shore A, its rubber element is engineered to hold heavier equipment firmly in place, absorbing shock and impact energy while resisting the displacement that softer grades allow under sustained or peak loading. The rubber-to-metal bonded construction combines a 40 mm diameter by 45 mm height body with M10 x 25 mm male threaded studs at both ends, offering straightforward inline installation between machine and structure. The mount may be loaded in shear, compression or a combination of both, making it adaptable to a range of mounting geometries without requiring additional hardware. At this hardness grade, the 4045MM25-70 suits applications where equipment must be restrained as much as isolated, diesel engines and generator sets running under variable load, industrial machinery and equipment subject to sudden shock, exhaust mountings exposed to mechanical stress, and air-conditioning units in commercial or industrial environments. It serves industries including power generation, construction and off-highway, marine, agriculture, and automotive. Custom variants using stainless steel metal parts or oil-resistant and high-temperature rubbers are available on request. This mount is part of a wider bobbin range.

A. The 4045MM25-70 has a maximum load rating of 73.0 kg per mount.
A. The rated deflection for the 4045MM25-70 is 4.1 mm at maximum load — a low-movement characteristic suited to applications requiring firm restraint.
A. The body measures 40 mm diameter by 45 mm height (D x H: 40 x 45 mm). Both threaded studs are M10 with a 25 mm stud length (d x L: M10 x 25 mm).
A. Harder rubber carries higher loads with less movement. The 70 Shore A grade is the correct choice where equipment must be firmly held — such as diesel engines, generator sets, or industrial machinery subject to shock and impact — rather than where maximum vibration isolation at lower loads is the priority.
A. The mount may be loaded in shear, compression or a combination of both, giving flexibility across different mounting geometries.
A. Source-confirmed applications include air-conditioning units, exhaust mountings, diesel engines, generator sets, industrial machinery and equipment. Industries served include power generation, construction and off-highway, agriculture, marine, and automotive.
A. Yes. The same 40x45 mm male-male geometry is available in 45 Shore A (SKU 4045MM25-45) for maximum deflection and isolation, and 60 Shore A (SKU 4045MM25-60) for a general-purpose balance of isolation and load capacity.
A. Yes — stainless steel metal parts and oil-resistant or high-temperature rubbers, as well as additional and custom sizes, are available on request.
