Where loads demand the firmest grip and the least give, the 40x20mm male-female bobbin mount in 70 Shore A rubber delivers: rated to a maximum of 109.0 kg with a minimal deflection of just 1.6 mm, this SKU (4020MF25-70) is built for applications where positional control under load is as important as vibration attenuation. The male stud is M10 x 25 mm and the female thread is M10, providing a clean male-to-female installation in moderate-load mainstream machinery across many industries. Rubber-to-metal bonded construction ensures the elastomer element remains securely united with its steel inserts under repeated shock and compression. The 70 Shore A compound sits at the firmer end of the elasticity spectrum, offering controlled movement rather than high deflection, a characteristic that suits heavier-duty mounting points on diesel engines, generator sets, and industrial machinery and equipment where the assembly must be firmly retained. Mounts of this geometry may be loaded in shear, compression, or a combination of both, broadening their usefulness across differing installation orientations. The 40 x 20 mm body (D x H) positions this mount firmly in the mid-range of the male-female bobbin family. Industry applications served by the range include construction and off-highway plant, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence. Exhaust mountings and air-conditioning units on engine-driven equipment represent further application contexts confirmed by the source family.

A. This mount is rated to a maximum load of 109.0 kg with a deflection of 1.6 mm, reflecting its 70 Shore A firm-grade rubber compound which prioritises positional control and minimal movement under load.
A. The male stud is M10 with a length of 25 mm (d1 x L: M10 x 25) and the female thread is M10 (d2: M10). The body dimensions are 40 mm diameter by 20 mm height (D x H: 40 x 20).
A. Harder rubber grades carry a higher maximum load with less deflection. The 70 Shore A compound in this mount is suited to applications requiring firm restraint, shock absorption, and load-bearing on heavier equipment — softer grades of the same geometry provide greater deflection and better isolation at lower loads.
A. These mounts may be loaded in shear, compression, or a combination of both, giving flexibility across differing installation orientations and mounting configurations.
A. The family source confirms suitability for diesel engines, generator sets, industrial machinery and equipment, air-conditioning units, and exhaust mountings. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. Yes — the same geometry is available in 45 Shore A (4020MF25-45) and 60 Shore A (4020MF25-60), which offer greater deflection and are suited to lighter loads and applications prioritising vibration isolation over firm restraint.
A. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, alongside additional and custom sizes.
A. Standard UK mainland delivery is 3–5 working days. Next-day delivery is available on most products and will appear as an option at checkout where eligible.
