Q 1. What are the dimensions and thread specification of this conical buffer?

A. The buffer measures 105 mm diameter by 121 mm height, with an M12 x 31 mm stud fixing.

Q 2. What is the maximum load and deflection rating for this buffer?

A. This buffer is rated to a maximum load of 420 kg with a deflection of 30 mm.

Q 3. What hardness grade is this conical buffer and what does that mean in practice?

A. This buffer is supplied in 60 Shore A, a medium grade that balances vibration isolation and load-bearing support. It suits applications where load conditions vary or where neither maximum deflection nor maximum stiffness is required.

Q 4. What applications is this conical buffer designed for?

A. It is suited to cushioning machinery against impact shocks from external moving components, and for primary or secondary suspension on industrial vehicles. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, and commercial vehicles.

Q 5. How can this buffer be loaded — compression, shear, or both?

A. This buffer can be loaded in shear, compression, or a combination of both, as confirmed by its rubber-to-metal bonded construction.

Q 6. Is this the largest buffer available in this conical family?

A. Yes — at 105 x 121 mm this is the largest body size in the MCB31 conical buffer range. Smaller variants are available, including 100100MCB31 and 10095MCB31.

Q 7. Are other hardness grades available in this 105 x 121 mm size?

A. Yes — the same 105 x 121 mm body is available in 45 Shore A (100120MCB31-45) for greater deflection and lighter loads, and 70 Shore A (100120MCB31-70) for higher load capacity and reduced movement.

Q 8. Are custom material or size options available for this buffer?

A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubbers, as well as additional and custom sizes, are available on request.

Q 9. Can I ask questions about this product before ordering?

A. Yes — WhatsApp us on 07754 288583 with any questions about specifications, suitability, or compatibility.

Q 10. Can I ask questions about this product before ordering?

A. Yes — WhatsApp us on 07754 288583 with any questions about specifications, suitability, or compatibility.
