Product Number: 7550FFB12-70
Variations
Carrying a maximum load of 1,040 kg with a controlled deflection of just 12.50 mm, the 7550FFB12-70 is the firm-grade variant of the 75 x 50 mm Female Flat Buffer range, engineered where high mass, shock loading, or the need to hold a component firmly under load demands the least possible give. The M12 female thread provides a secure, positive fixing, and the rubber-to-metal bonded construction ensures the element remains stable under the compressive and shear forces typical of demanding industrial duty. At 70 Shore A, the rubber compound is formulated for applications where softer grades would deflect too far or fail to maintain positional control under peak loads. Energy is absorbed and dissipated through the rubber body, cushioning machinery against impact shocks from external moving components whilst resisting the creep that lower-hardness grades exhibit under sustained heavy load. The result is dependable shock attenuation without the structural movement that harder-to-control applications cannot tolerate. The 7550FFB12-70 is suited to construction and off-highway equipment, heavy agricultural machinery, commercial vehicles, power generation plant, and marine and railway applications where robust restraint and high-load shock management are priorities. It may also function as a bump stop or elastic element in direct contact with a surface, and contributes to improved machinery lifespan, protection of surrounding structures, and enhanced operator comfort. Custom specifications including stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request. This buffer is available in alternative hardness grades: 45 Shore A (7550FFB12-45) and 60 Shore A (7550FFB12-60).

A. The buffer measures 75 mm diameter by 50 mm height with an M12 female thread. It has a maximum load capacity of 1,040 kg and a deflection of 12.50 mm.
A. At 70 Shore A, this is the firmest grade in the M12 flat buffer range. Harder grades carry higher loads with less movement, making them the appropriate choice where positional control under heavy or shock loading is required. Softer grades offer greater deflection and better isolation at lower loads.
A. The 7550FFB12-70 is suited to construction and off-highway equipment, heavy agricultural machinery, commercial vehicles, power generation plant, and marine and railway applications. It may be used as a bump stop or as an elastic element in direct contact with a surface.
A. The rubber-to-metal bonded construction works by absorbing and dissipating energy through the rubber body, cushioning machinery against impact shocks from external moving components. The M12 female thread provides secure fixing, and the buffer can be loaded in compression, shear, or a combination of both.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
A. This buffer is available in 45 Shore A (7550FFB12-45) and 60 Shore A (7550FFB12-60). The M16-thread flat buffer family includes sizes 100 x 100 mm (100100FFB16), 100 x 30 mm (10030FFB16), 100 x 40 mm (10040FFB16), 100 x 50 mm (10050FFB16), 100 x 55 mm (10055FFB16), and 100 x 60 mm (10060FFB16).
