Product Number: 7525FFB12-45
Variations
Measuring 75 mm diameter by 25 mm height with an M12 female thread, this 45 Shore A flat buffer is engineered to deliver maximum vibration isolation across a broad range of general industrial applications. At the softest end of the 75x25 M12 flat buffer range, the 45 Shore A grade undergoes up to 6.25 mm of deflection under load, making it the preferred choice wherever compliance and energy absorption take priority over stiffness or positional restraint. Rubber-to-metal bonded construction gives the buffer structural integrity whilst allowing the rubber element to work freely in compression, shear, or a combination of both. This soft grade is well suited to lighter or vibration-sensitive equipment, including agricultural machinery, power generation plant, and marine installations. Where absorbing and dissipating energy from lower-frequency vibration sources is the primary requirement. The generous deflection characteristic means the mount accommodates movement that would overload a harder grade, protecting surrounding structures and improving operator comfort in the process. The 7525FFB12-45 carries a rated maximum load of 900 kg. Mounting hardware engages directly with the M12 female thread, simplifying installation and keeping the assembly low-profile. Industries such as construction and off-highway, railway and mass transit, and automotive manufacturing rely on flat buffers of this geometry to cushion machinery against impact shocks from external moving components and to reduce the transmission of vibration into supporting frames. This buffer is available in firmer grades for higher-load or greater-restraint duties: 60 Shore A (SKU 7525FFB12-60) and 70 Shore A (SKU 7525FFB12-70).

A. The 7525FFB12-45 is rated to a maximum load of 900 kg and provides up to 6.25 mm of deflection under load.
A. The buffer measures 75 mm diameter by 25 mm height (D x H: 75 x 25) and features an M12 female thread.
A. The 45 Shore A grade is the softest option in the 75x25 M12 flat buffer range. Softer grades give greater deflection and better vibration isolation at lower loads, making this grade the right choice for lighter or vibration-sensitive equipment where isolation matters more than positional restraint. Harder grades — 60 Shore A (7525FFB12-60) and 70 Shore A (7525FFB12-70) — carry higher loads with less movement.
A. This buffer is used across construction and off-highway, agriculture, power generation, marine, railway and mass transit, and automotive industries. It cushions machinery against impact shocks from external moving components and reduces vibration transmission into supporting structures, improving machinery lifespan and operator comfort.
A. Flat buffers of this type may be loaded in compression, shear, or a combination of both, working by absorbing and dissipating energy from vibration and impact sources.
A. The buffer uses rubber-to-metal bonded construction. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request.
A. Yes — the female flat buffer range extends to larger footprints including 100x100 mm (SKU 100100FFB16), 100x30 mm (SKU 10030FFB16), 100x40 mm (SKU 10040FFB16), 100x50 mm (SKU 10050FFB16), 100x55 mm (SKU 10055FFB16), and 100x60 mm (SKU 10060FFB16).
