Lighter equipment demands a mount that yields, and this 40 x 25 mm Female Flat Buffer with M8 thread and 45 Shore A natural rubber delivers exactly that, offering maximum deflection of 6.25 mm under a rated maximum load of 139.0 kg, making it the softest grade in this geometry and the right choice wherever isolation takes priority over restraint. At 45 Shore A, the rubber compound is calibrated to give the greatest movement under load within this flat-buffer family, absorbing and dissipating vibrational energy most effectively at lower excitation forces and lower-frequency inputs, a characteristic that makes it particularly well suited to sensitive instruments, light-duty industrial machinery, and compact installations where minimising transmitted vibration matters more than carrying high static loads. Rubber-to-metal bonded construction unites the natural rubber element with its steel ferrule to form a single, reliable assembly that resists separation under service conditions. The female threaded M8 insert allows direct bolting to a mating male stud or threaded surface without additional hardware, keeping installation straightforward. Being a flat-buffer geometry, this mount operates primarily in compression, cushioning direct contact between a moving or vibrating component and a structural surface, and the soft grade ensures the energy path is interrupted early, before shock forces propagate into surrounding structures or operator environments.

A. The buffer measures 40 mm diameter by 25 mm height, carries an M8 female thread, has a maximum load rating of 139.0 kg, and delivers a deflection of 6.25 mm under load.
A. At 45 Shore A, this is the softest grade in the 40 x 25 mm M8 flat-buffer family. It gives the greatest deflection — 6.25 mm — under load, which translates to superior vibration isolation at lower excitation forces. It is the appropriate choice where isolating sensitive or light equipment takes priority over carrying high static loads or resisting significant movement.
A. The 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. The 45 Shore A soft grade is best suited to lighter-load and sensitivity-critical applications within those sectors.
A. The buffer absorbs and dissipates energy by deflecting in compression between a vibrating or moving component and a structural surface. The female M8 threaded insert allows the buffer to be bolted directly onto a matching male stud or threaded fastener without additional hardware, making installation straightforward.
A. The buffer uses rubber-to-metal bonded construction, uniting the natural rubber element with its steel ferrule as a single assembly. This bonded construction resists separation under normal service conditions.
A. Yes — the same geometry is offered in 60 Shore A medium grade (4025FFB08-60) and 70 Shore A firm grade (4025FFB08-70). Harder grades carry higher loads with less movement; the 45 Shore A grade here provides the most deflection and the best isolation performance at lighter loads.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
