Q 1. What is the maximum load and deflection for the 7589MCB37-70?

A. This buffer has a maximum load rating of 279.8 kg and a deflection of 21.2 mm.

Q 2. What do the dimensions M12 x 37 and 75 x 89 mm refer to?

A. 75 x 89 mm is the outer diameter by height of the conical buffer body. M12 x 37 refers to the threaded stud — M12 thread diameter with a 37 mm stud length.

Q 3. Why choose a 70 Shore A grade over a softer conical buffer?

A. At 70 Shore A, this is the firm grade in the family. It carries higher loads with less movement than the 45 or 60 Shore A variants, making it suited to heavier, shock-loaded, or restraint applications where minimal deflection is required.

Q 4. What types of equipment is this conical buffer designed for?

A. The buffer is suited to industrial vehicles (primary and secondary suspension), construction and off-highway equipment, agricultural machinery, power generation, marine, railway and mass transit, and military and defence applications. Mounts may be loaded in shear, compression, or a combination of both.

Q 5. How does this buffer protect machinery and operators?

A. The rubber-to-metal bonded construction absorbs and dissipates impact energy from external moving components rather than transmitting it, helping to extend machinery lifespan, protect surrounding structures, and improve operator comfort.

Q 6. Are custom materials or sizes available for this conical buffer?

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

Q 7. What other Shore grades and sizes are available in this conical buffer range?

A. The 75 x 89 mm / M12 body is also available in 45 Shore A (7589MCB37-45) and 60 Shore A (7589MCB37-60). Related geometries include 100100MCB31, 100120MCB31, 10095MCB31, 1010MCB12, 11877MCB41, and 2015MCB10.
