Q 1. What is the maximum load rating and deflection for the 2514MCB20-45?

A. This 45 Shore A conical buffer is rated to a maximum load of 35 kg with a deflection of 3.5 mm. The relatively high deflection for this load reflects the softer 45 Shore A hardness grade, which prioritises vibration isolation and energy absorption over stiffness.

Q 2. What does a 45 Shore A hardness grade mean for performance?

A. 45 Shore A places this buffer at the softer end of the conical range. Softer grades give greater deflection and better isolation at lower load, making this variant most appropriate for lighter or sensitive equipment and installations where damping low-frequency vibration is the primary requirement rather than high load-carrying capacity or movement restraint.

Q 3. What are the physical dimensions and thread specification of this buffer?

A. The buffer body measures 25 mm in diameter by 14 mm in height. The male stud is M8 with a thread length of 20 mm.

Q 4. What applications is this soft-grade conical buffer suited to?

A. This 45 Shore A variant is well suited to agricultural equipment, smaller industrial machinery, elevators, and commercial vehicles where the objective is cushioning low-amplitude vibration and protecting sensitive surrounding structures. The conical buffer form is also used for primary and secondary suspension of industrial vehicles.

Q 5. How does the conical buffer absorb shock and vibration?

A. The rubber-to-metal bonded construction allows the elastomer to accept loading in compression, shear, or a combination of both. The buffer works by absorbing and dissipating energy from external moving components, reducing transmitted impact force and improving operator comfort and machinery lifespan.

Q 6. Are other Shore hardness grades available in the same 25x14mm M8 size?

A. Yes. The same 25x14mm M8 geometry is also available in 60 Shore A (SKU 2514MCB20-60) for general-purpose mid-load duties and 70 Shore A (SKU 2514MCB20-70) for higher-load or higher-restraint applications. Select the harder grade where load is greater or movement must be more tightly controlled.

Q 7. Are custom materials or non-standard sizes available for this buffer type?

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

Q 8. When will my order be dispatched?

A. In-stock orders placed before 14:30 Monday to Friday are usually dispatched the same day.
