Where vibration isolation takes priority over load restraint, the 40x30mm Female Flat Buffer with M10 thread and 45 Shore A rubber hardness is the correct specification. At this softer grade, the mount yields a maximum deflection of 7.50mm under a rated load of 119.0kg, characteristics that make it well-suited to lighter, compact or sensitive installations where absorbing low-frequency vibration energy is the primary engineering objective rather than limiting movement. Constructed with rubber-to-metal bonding throughout, this female flat buffer absorbs and dissipates impact shocks and vibration transmitted from external moving components. The 45 Shore A formulation sits at the softer end of the hardness range, delivering greater compliance under load; this translates directly into superior isolation performance for equipment that is susceptible to vibration damage or where operator comfort is a key consideration. Softer grades such as this are the appropriate choice when the mount will be loaded at lower forces and movement must be permitted to attenuate energy effectively. Typical applications span construction equipment, industrial machinery, agricultural equipment, commercial vehicles and elevators, as well as power generation, marine, railway and automotive installations. In each setting, the 40x30mm body geometry and M10 female fixing provide a dependable interface between structure and component. The mount may be loaded in compression, shear, or a combination of both. By cushioning machinery against impact shocks, it protects surrounding structures, reduces fatigue on fixings and improves the service life of the wider assembly.

A. The buffer measures 40mm diameter by 30mm height with an M10 female thread. It is rated to a maximum load of 119.0kg and offers a deflection of 7.50mm at that load. Rubber hardness is 45 Shore A.
A. Shore A hardness indicates the firmness of the rubber compound. At 45 Shore A, this is a softer grade that provides greater deflection under load — up to 7.50mm — and delivers better vibration isolation performance, particularly for lighter or sensitive equipment and lower-frequency vibration. Harder grades carry higher loads with less movement.
A. This buffer is used across construction equipment, industrial machinery, agricultural equipment, commercial vehicles and elevators, as well as power generation, marine, railway, automotive, and military and defence applications. It is particularly appropriate where vibration isolation is the primary concern rather than high load restraint.
A. Female flat buffers may be loaded in compression, shear, or a combination of both. The rubber-to-metal bonded construction absorbs and dissipates energy from impact shocks and vibration transmitted by external moving components.
A. Yes. The same 40x30mm M10 female flat buffer geometry is available in 60 Shore A (SKU: 4030FFB10-60) and 70 Shore A (SKU: 4030FFB10-70) for applications requiring higher load capacity or reduced deflection.
A. Yes. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
