Sensitive installations and lighter machinery loads call for a buffer that prioritises absorption over restraint, the 30x17mm Male Flat Buffer in 45 Shore A (SKU: 3017MFB20-45) is engineered precisely for that role. At the softer end of the hardness range, this rubber-to-metal bonded component delivers maximum deflection of 4.25 mm under a maximum load of 82.0 kg, making it well suited to lower-frequency vibration isolation where movement compliance reduces transmitted energy more effectively than stiffness. Constructed with a rubber-to-metal bonded body on a male M8 x 20 mm stud, the flat buffer profile allows direct elastic contact with a surface or secondary object. At 45 Shore A, the rubber compound yields readily under load, absorbing and dissipating impact energy with the greatest compliance in the hardness range. This characteristic makes the soft grade the preferred choice where protecting delicate components, reducing operator discomfort on sensitive equipment, or isolating lower-amplitude vibration sources is the primary objective. With overall dimensions of 30 mm diameter by 17 mm height, this compact buffer suits light-duty applications across agricultural machinery, commercial vehicles, elevators, and industrial equipment where structural clearances are tight and load demands remain within the soft-grade envelope. It may be loaded in shear, compression, or a combination of both. Industries served include construction and off-highway, power generation, marine, railway and mass transit, and automotive sectors. Custom configurations in stainless steel fixings or oil-resistant and high-temperature rubbers are available on request.

A. The buffer has an overall diameter of 30 mm and height of 17 mm, with an M8 x 20 mm male stud. It is rated to a maximum load of 82.0 kg with a deflection of 4.25 mm.
A. At 45 Shore A, this is the softer hardness grade in the range. Softer rubber yields more readily under load, providing greater deflection and better isolation — particularly at lower frequencies or on lighter, more sensitive equipment where minimising transmitted vibration matters more than limiting movement.
A. The 30x17mm 45 Shore A flat buffer is suited to agricultural machinery, commercial vehicles, elevators, and industrial equipment operating at lighter loads. It serves industries including construction and off-highway, power generation, marine, railway and mass transit, and automotive.
A. The rubber-to-metal bonded construction allows it to act as an elastic element in direct contact with a surface, or to cushion against impact from a secondary moving component. It can be loaded in shear, compression, or a combination of both, and the M8 male stud provides a straightforward threaded fixing point.
A. Yes — the same 30x17mm Male Flat Buffer is available in 60 Shore A (SKU: 3017MFB20-60) and 70 Shore A (SKU: 3017MFB20-70) for higher-load or greater-restraint applications. A wider range of sizes is also available; see SKUs 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
A. Yes — stainless steel metal components and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
