Holding heavy loads demands a mount built to resist movement, and the 40x20mm Male-Male Bobbin Mount in 70 Shore A (SKU: 4020MM25-70) is engineered precisely for that role. Rated to a maximum load of 106.0 kg with a deflection of just 1.6 mm, this firm-grade mount is the right choice where structural firmness and shock absorption under heavier duty conditions take priority over isolation travel. The M10 x 25 mm studded male-male thread configuration allows direct in-line installation between two mating components without additional brackets. Constructed using rubber-to-metal bonded technology, the 70 Shore A rubber element delivers controlled compliance under compression, shear, or combined loading, making it well suited to applications where the mounted item must be held firmly against shock and impact forces. The higher durometer rating means movement is tightly governed even when dynamic loads spike, a meaningful distinction for industrial machinery, generator sets, and diesel engine installations where positional drift would be unacceptable. The 40 x 20 mm body geometry (D x H) positions this mount within the standard load band of the male-male bobbin range, serving mainstream general-machinery mounting at moderate-to-firm load levels. Applications served by the family include air-conditioning units, exhaust mountings, generator sets, diesel engines, instruments, and a broad range of industrial machinery and equipment across construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence sectors. This mount is one of several bobbin configurations available.

A. This 70 Shore A bobbin mount is rated to a maximum load of 106.0 kg with a deflection of 1.6 mm under that load, reflecting the firm rubber grade's resistance to movement.
A. The mount uses M10 threaded studs with a length of 25 mm (d x L: M10 x 25), in a male-male configuration for direct in-line bolting between two components.
A. The body measures 40 mm in diameter by 20 mm in height (D x H: 40 x 20 mm).
A. The mount may be loaded in shear, compression, or a combination of both, as is standard across this bobbin family.
A. The 70 Shore A grade carries higher loads with less movement than softer grades. It is the appropriate choice where the mounted component must be held firmly against shock and impact forces rather than maximising vibration isolation travel. Softer grades in the same 40x20mm body — 45 Shore A (4020MM25-45) and 60 Shore A (4020MM25-60) — offer greater deflection and better isolation at lower loads.
A. The male-male bobbin family is designed for air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and general industrial machinery and equipment. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. Yes — stainless steel metal parts and oil-resistant or high-temperature rubber compounds are available on request, as are custom sizes outside the standard range.
