The 4025MFB25-70 is a 40 x 25 mm male flat buffer rated to a maximum load of 281.5 kg with a deflection of just 6.3 mm, figures that reflect the firm resistance of its 70 Shore A rubber compound and make it the correct choice where machinery must be held securely under heavy or shock-imposed loads. The M10 x 25 mm male stud provides direct, tool-accessible installation without the need for brackets or adaptors. Rubber-to-metal bonded construction ensures the rubber element remains positively located under cyclic loading. At 70 Shore A, the compound prioritises load capacity and positional restraint: deflection is deliberately limited, so the buffer acts as a firm stop rather than a compliant isolator, absorbing and dissipating impact energy whilst preventing excessive component travel. This makes it well suited to applications in construction equipment, commercial vehicles, and agricultural machinery where impacts are high-energy and repeatable. The male flat geometry positions this buffer as a low-cost solution for direct-contact elastic elements and secondary impact management, for example as a bump stop against a moving structural member or as an end-of-travel restraint on industrial vehicle bodywork. Industries served by this family include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence. The flat-face profile allows full-face contact with mating surfaces and distributes compressive load evenly across the rubber element.

A. The 4025MFB25-70 has a maximum load capacity of 281.5 kg and a deflection of 6.3 mm. The 70 Shore A rubber compound delivers firm resistance, making it suitable for heavy or impact-dominated loading where minimal movement is required.
A. At 70 Shore A, the rubber is at the firmer end of the range. Harder grades carry higher loads with less deflection, so this buffer acts as a positive stop or firm restraint rather than a soft isolator. Softer grades — such as 45 or 60 Shore A — give greater deflection and are better suited to lower loads and vibration isolation.
A. The buffer body measures 40 mm diameter by 25 mm height (D x H). The male stud is M10 with a 25 mm thread length (d x L: M10 x 25).
A. This buffer is designed for shock and impact absorption in construction equipment, agricultural machinery, commercial vehicles, industrial machinery, and elevators. It is used as a direct-contact elastic element or bump stop — for example, cushioning a moving structural component or acting as an end-of-travel restraint on vehicle bodywork.
A. Male flat buffers absorb and dissipate energy from an impacting object through the deflection of the rubber element. The flat face allows full-contact loading in compression. The rubber-to-metal bonded construction keeps the rubber positively located under repeated loading cycles, protecting the surrounding structure and improving machinery lifespan.
A. Yes. The 40 x 25 mm M10 buffer is also available in 45 Shore A (4025MFB25-45) and 60 Shore A (4025MFB25-60). The wider range includes sizes such as 0808MFB06, 10030MFB41, 10040MFB44, 10050MFB41, 10055MFB44, and 100100MFB44. Custom sizes, stainless steel metalwork, and oil-resistant or high-temperature rubber compounds are also available on request.
