Where vibration isolation takes priority over load restraint, the 7550FFB12-45 Female Flat Buffer delivers. Measuring 75 mm diameter by 50 mm height with an M12 female thread, this 45 Shore A soft-grade rubber buffer is engineered for lighter or sensitivity-critical equipment where maximum energy dissipation and compliance under load matter most. It accepts up to 505 kg and yields 12.50 mm of deflection, a generous travel figure that enables this grade to absorb low-frequency vibration inputs that stiffer compounds would transmit rather than filter. Constructed using rubber-to-metal bonded technology, the buffer works by absorbing and dissipating impact energy rather than merely resisting it. The soft 45 Shore A compound provides greater deflection and superior isolation performance at moderate load levels, making it well suited to applications where operator comfort, instrument protection, or the safeguarding of sensitive components takes precedence. Mounts of this type may be loaded in compression, shear, or a combination of both, giving design engineers flexibility in how they orient the element within an assembly. Typical application areas include agricultural equipment, power generation plant, marine installations, and light industrial machinery, environments where lower-frequency vibration is commonplace and where the equipment or its surroundings benefit from maximum cushioning compliance. The buffer also plays a role in reducing transmitted shock between secondary moving components and fixed structures, protecting surrounding infrastructure and extending the operational life of the machinery to which it is fitted.

A. The buffer measures 75 mm diameter by 50 mm height (D x H: 75 x 50) with an M12 female thread. It has a maximum load rating of 505.0 kg and a deflection figure of 12.50 mm.
A. The 45 Shore A is the softest grade in this geometry, providing greater deflection under load and superior vibration isolation, particularly at lower frequencies. It is best suited to lighter or sensitivity-critical equipment where compliance and energy dissipation matter more than high load restraint.
A. This buffer is suited to agricultural equipment, marine installations, power generation plant, and light industrial machinery — wherever low-frequency vibration isolation and impact cushioning are the priority. It also finds use in construction equipment, commercial vehicles, and applications requiring protection of sensitive surrounding structures.
A. It uses rubber-to-metal bonded construction and functions by absorbing and dissipating energy from impact or vibration inputs. The element can be loaded in compression, shear, or a combination of both, giving flexibility in mounting orientation.
A. Yes. The same 75 x 50 mm M12 geometry is available in 60 Shore A (SKU: 7550FFB12-60) for general-purpose moderate-to-higher loads, and 70 Shore A (SKU: 7550FFB12-70) for firmer, high-load or shock-restraint applications.
A. Yes. Larger-diameter flat buffers with M16 thread are available in this family, including SKUs 100100FFB16, 10030FFB16, 10040FFB16, 10050FFB16, 10055FFB16, and 10060FFB16.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes.
A. The 7550FFB12-45 is supplied as an individual unit.
