Where isolation takes priority over restraint, the Female Flat Buffer 3020FFB06-45 delivers. Rated to a maximum load of 77.0 kg with a generous 5.0 mm deflection, this 30 x 20 mm, M6-threaded buffer is engineered for lighter and compact installations where the softest available Shore grade, 45 Shore A. Produces maximum vibration absorption and the greatest movement under load, separating sensitive equipment from the shock and vibration energy that shortens service life. Constructed with rubber-to-metal bonded technology, the buffer works by absorbing and dissipating impact energy on contact, cushioning machinery against shock from external moving components. The 45 Shore A compound is the softest in the flat buffer range: at any given load, softer grades produce greater deflection and superior isolation compared with harder grades, making this variant the first choice where lower-frequency vibration isolation matters more than stiffness or load restraint. Applications particularly well matched to the 45 Shore A grade include sensitive instrumentation mounting, lighter agricultural equipment, compact power-generation units, and installations on commercial or industrial machinery where operator comfort and protection of surrounding structures are primary concerns. The buffer may be loaded in compression, shear, or a combination of both. Custom options, including oil-resistant or high-temperature rubber compounds and stainless steel metalwork. Are available on request. This SKU is the soft-grade variant within the 30 x 20 mm M6 Female Flat Buffer family.

A. This buffer has a maximum load rating of 77.0 kg and a deflection of 5.0 mm, making it suited to lighter and compact installations where generous movement under load is required.
A. Shore A is a measure of rubber hardness. At 45 Shore A, this is the softest grade in the flat buffer range: softer compounds produce greater deflection and better vibration isolation at lower loads, prioritising isolation over load restraint. Harder grades carry higher loads with less movement.
A. The soft 45 Shore A grade is well suited to sensitive or lighter equipment — including compact agricultural machinery, lighter industrial equipment, power-generation units, and applications where lower-frequency vibration isolation and operator comfort take priority.
A. The buffer uses rubber-to-metal bonded construction to absorb and dissipate energy on impact or vibration contact. It may be loaded in compression, shear, or a combination, cushioning machinery against shock from external moving components and protecting surrounding structures.
A. Yes. The same 30 x 20 mm M6 geometry is available in 60 Shore A (3020FFB06-60) and 70 Shore A (3020FFB06-70) for applications requiring higher load capacity or reduced deflection.
A. Yes. Oil-resistant and high-temperature rubber compounds, stainless steel metalwork, and additional custom sizes are available on request.
A. We accept returns within 30 days of purchase for items that are unused, undamaged, and in their original packaging. Returns are available only for UK-delivered orders and must include proof of purchase. Before returning an item, please contact us at [email protected] to obtain a Return Merchandise Number (RMN).
