Product Number: 2025FFB06-45
Engineered for sensitive and lighter-duty installations where maximum vibration isolation takes priority, this 20x25mm Female Flat Buffer with M6 thread and 45 Shore A rubber delivers the greatest deflection in the flat buffer range at this geometry, up to 6.25mm under its rated maximum load of 27.5kg. Where softer, more compliant mounting is needed to absorb low-frequency vibration energy rather than restrain movement, the 45 Shore A grade is the correct selection for this size. The rubber-to-metal bonded construction allows the buffer to be loaded in compression, shear, or a combination of both, absorbing and dissipating impact energy rather than transmitting it to surrounding structures. At 45 Shore A, the rubber compound yields more readily under load than harder grades, making it well suited to equipment that is lightweight, vibration-sensitive, or subject to lower-frequency excitation where isolation efficiency is more important than load capacity or positional restraint. Typical applications include light industrial machinery, agricultural equipment, marine installations, power generation equipment, and sensitive instrumentation panels subject to external shock or vibration. The female M6 threaded insert provides secure attachment and straightforward installation, reducing assembly time without specialist tooling. This buffer also contributes to improved operator comfort and extended machinery service life by limiting vibration transmission to adjacent components and supporting structures. This product is available in harder grades for higher-load or restraint-critical duties: 60 Shore A (SKU 2025FFB06-60) and 70 Shore A (SKU 2025FFB06-70).

A. The buffer measures 20mm diameter by 25mm height (D x H: 20 x 25), uses an M6 female threaded insert, is rated to a maximum load of 27.5kg, and provides a deflection of 6.25mm at that load. The rubber hardness is 45 Shore A.
A. The 45 Shore A grade offers the greatest deflection at this size — 6.25mm — making it most effective where maximum vibration isolation is the priority rather than positional restraint. It is the correct choice for lighter or vibration-sensitive equipment, lower-frequency excitation, and installations where the mount should yield compliantly rather than resist movement.
A. This buffer is suited to light industrial machinery, agricultural equipment, marine installations, power generation equipment, and applications in construction, automotive, and railway environments. It is particularly appropriate where sensitive components or operator comfort must be protected from externally generated shock and vibration.
A. The rubber-to-metal bonded construction allows the buffer to be loaded in compression, shear, or a combination of both. It works by absorbing and dissipating impact energy, reducing the force transmitted to surrounding structures and connected machinery rather than reflecting it.
A. Yes. The same 20x25mm M6 flat buffer is available in 60 Shore A (SKU 2025FFB06-60) for general-purpose duties and 70 Shore A (SKU 2025FFB06-70) for higher-load or shock-restraint applications. Harder grades carry greater load with less movement; softer grades such as this 45 Shore A provide greater deflection and better isolation at lower loads.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes beyond the standard range.
