Q 1. What are the key dimensions and load rating for the 6030MFB37-45?

A. The buffer measures 60 mm in diameter by 30 mm in height, with an M12 x 37 mm male threaded stud. It is rated to a maximum load of 436.0 kg and provides up to 7.5 mm of deflection at that load.

Q 2. What does the 45 Shore A hardness grade mean in practice?

A. Shore A 45 is the softest grade available in this flat buffer geometry. Softer rubber deflects more under a given load, which means greater energy absorption and better vibration isolation — particularly at lower frequencies. It is best suited to lighter or more sensitive equipment where isolation performance matters more than high-load restraint.

Q 3. What types of equipment and industries is this buffer designed for?

A. This buffer is used across a broad range of applications including agricultural equipment, elevators, power generation plant, construction and off-highway machinery, commercial vehicles, marine installations, and railway and mass transit systems. It cushions against impact shocks from external moving components and reduces vibration transmitted to surrounding structures.

Q 4. How does this buffer work to protect machinery?

A. The bonded rubber-to-metal construction absorbs and dissipates energy from vibration and impact forces. It can be loaded in compression, shear, or a combination of both, reducing the force transmitted to the mounting structure, improving machinery lifespan, protecting surrounding components, and improving operator comfort.

Q 5. Are other Shore A hardness grades available in the same 60 x 30 mm size?

A. Yes. The same 60 x 30 mm footprint with M12 x 37 mm stud is available in 60 Shore A (6030MFB37-60) and 70 Shore A (6030MFB37-70) for applications requiring higher load capacity with less deflection.

Q 6. Are custom specifications available for this buffer type?

A. Yes. Stainless steel metal components and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes.

Q 7. How long does delivery take?

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.

Q 8. What is your returns policy?

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).
