Q 1. What are the key dimensions and load specifications for MCB3460*-45?

A. The buffer measures 70 mm diameter by 46 mm height (D x H), with an M12 x 30 mm male stud (d x L). Maximum rated load is 178.0 kg and maximum deflection is 11.5 mm.

Q 2. Why choose the 45 Shore A grade rather than a firmer grade of this buffer?

A. At 45 Shore A, this is the softest grade in the conical buffer range, producing the greatest deflection — 11.5 mm — under load. This makes it the correct choice when the priority is maximum vibration isolation rather than load restraint, particularly for lighter or vibration-sensitive equipment and lower-frequency isolation applications.

Q 3. What applications is the MCB3460*-45 conical buffer suited to?

A. It is suited to primary and secondary suspension duties on industrial vehicles and as anti-shock bump stops for machinery subject to impacts from external moving components. Typical end-use sectors include agriculture, power generation, elevators, light commercial vehicles, and construction and off-highway equipment where low-frequency isolation is the governing requirement.

Q 4. How is this conical buffer constructed?

A. The buffer uses rubber-to-metal bonded construction, combining a vulcanised rubber element with metal end fittings. This bonded design maintains alignment, resists separation under cyclic loading, and provides consistent deflection characteristics throughout its service life.

Q 5. Can this buffer be loaded in different directions?

A. Yes. Conical buffers of this type may be loaded in shear, compression, or a combination of both, depending on the mounting arrangement and the direction of the forces applied in service.

Q 6. Are other Shore hardness grades available in this 70 x 46 mm conical buffer size?

A. Yes. This buffer is also available in 60 Shore A (MCB3460*-60) and 70 Shore A (MCB3460*-70) for applications requiring higher load capacity and reduced deflection.

Q 7. Are custom specifications available for this conical buffer?

A. Yes. Stainless steel metalwork, oil-resistant rubber compounds, high-temperature rubber compounds, and additional or custom sizes are all available on request.

Q 8. What if my order arrives damaged or incorrect?
