Product Number: 3040MFB20-70
Rated at a maximum load of 108.5 kg with a controlled deflection of just 10.0 mm, the Male Flat Buffer 3040MFB20-70 is the firm-grade option in the 30x40mm flat buffer range, engineered for applications where loads are heavier, impacts are sharp, and the mounted component must be held with minimal give. Its rubber-to-metal bonded construction delivers reliable shock and vibration absorption in direct contact with a surface or as an elastic element resisting an external moving component. At 70 Shore A, this buffer is purpose-built for situations demanding high load capacity and resistance to displacement. The harder rubber compound carries loads that softer grades cannot sustain without excessive movement, making it the correct selection for robust machinery, impact-intensive environments, and installations where positional stability under load is a primary requirement. Energy is absorbed and dissipated through the rubber body, reducing the force transmitted to surrounding structures and extending machinery service life. Applications drawing on this performance profile include construction and off-highway equipment, agricultural machinery, commercial vehicles, industrial machinery, and power generation plant, wherever a compact 30x40mm footprint must manage significant compressive or combined loading. The M8x20 stud provides a straightforward single-fixing installation. Stainless steel hardware and oil-resistant or high-temperature rubber compounds are available on request for demanding environments. This 70 Shore A buffer is one of three hardness grades available in the 30x40mm Male Flat Buffer family.

A. This buffer has a maximum load rating of 108.5 kg and a deflection of 10.0 mm, making it the firm-grade choice in the 30x40mm family for applications requiring high load capacity with minimal movement.
A. At 70 Shore A, this is the hardest grade in the 30x40mm Male Flat Buffer range. Harder grades carry higher loads with less deflection, so this buffer suits heavy-duty, shock-intensive, or impact-prone installations where the mounted component must remain firmly positioned rather than deflecting freely.
A. This buffer is suited to construction and off-highway equipment, agricultural machinery, commercial vehicles, industrial machinery, power generation plant, and similar applications where a compact 30x40mm buffer must absorb and dissipate significant compressive or combined shock loading.
A. The rubber-to-metal bonded body absorbs and dissipates impact and vibration energy, reducing force transmitted to surrounding structures. It is installed via its M8x20 male stud fixing, either in direct contact with a surface or as an elastic element between a moving component and a static structure.
A. Yes. The 30x40mm Male Flat Buffer is also available in 45 Shore A (3040MFB20-45) and 60 Shore A (3040MFB20-60) for applications requiring greater deflection and improved isolation at lighter loads. Larger footprint variants include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
A. Yes. Stainless steel metal components and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes.
A. Standard UK mainland delivery is 3–5 working days. Next-day delivery is available on most products and will appear as an option at checkout where eligible.
A. We accept returns within 30 days of purchase for items that are unused, undamaged, and in their original packaging.
