Variations
Yielding under load with a maximum deflection of 10.0 mm, this 70 x 40 mm male flat buffer at 45 Shore A is the softest grade in the 70 x 40 family, calibrated for equipment where vibration isolation takes priority over restraint. Rated to a maximum load of 494.5 kg and carrying an M12 x 37 stud, it is suited to lighter or sensitive machinery where the rubber must absorb and dissipate energy at lower frequencies rather than resist high dynamic forces. Rubber-to-metal bonded construction keeps the assembly compact and ensures the stud anchor remains secure under repeated deflection cycles. The flat-face geometry places the buffer in direct contact with a secondary surface, making it straightforward to install as a bump stop or elastic contact element. At 45 Shore A, the softer compound delivers greater deflection per unit of applied load than harder grades, which translates to a measurably superior isolation effect for lower-frequency vibration sources. Custom variants in oil-resistant or high-temperature rubbers, and stainless steel metalwork, are available on request. Application areas supported by the family include construction equipment, agricultural machinery, industrial plant, elevators, and commercial vehicles. The combination of a large 70 mm diameter footprint and a compliant 45 Shore A compound makes this SKU particularly well matched to general machinery mounting at moderate load levels, where the goal is protecting sensitive components or improving operator comfort rather than hard restraint. Industries served include agriculture, power generation, marine, and railway and mass transit.

A. The buffer measures 70 mm diameter by 40 mm height (D x H: 70 x 40), with an M12 x 37 mm male stud (d x L: M12 x 37).
A. The 7040MFB37-45 is rated to a maximum load of 494.5 kg and offers a deflection of 10.0 mm, reflecting the greater compliance of the soft 45 Shore A compound under load.
A. Softer grades such as 45 Shore A give greater deflection and better vibration isolation at lower loads and lower frequencies. Where protecting sensitive equipment or improving operator comfort is the priority, rather than restraining high dynamic forces, the 45 Shore A compound is the appropriate choice.
A. The male flat buffer family is used in construction equipment, industrial machinery, agricultural equipment, elevators, and commercial vehicles. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. The flat-face rubber-to-metal bonded design allows the buffer to absorb and dissipate energy when a secondary object makes contact with its face, or when it acts as an elastic element in direct contact with a surface. This cushions impact shocks and reduces transmitted vibration to surrounding structures and operators.
A. Yes. The same 70 x 40 mm geometry is available in 60 Shore A (7040MFB37-60) and 70 Shore A (7040MFB37-70) for applications requiring higher load capacity with less deflection.
A. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request, along with 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.
