Q 1. What load and deflection does the 5040FFB10-60 support?

A. This buffer is rated to a maximum load of 257.0 kg with a deflection of 10.00 mm, making it suitable for moderate-to-substantial machinery mounting duties at a balanced mid-range hardness.

Q 2. What does the 60 Shore A hardness grade mean in practice?

A. At 60 Shore A, this buffer sits in the mid-range of the hardness scale, providing a balance between vibration isolation and load-bearing support. Softer grades offer greater deflection at lighter loads; harder grades carry higher loads with less movement. The 60 Shore A grade is well matched to general-purpose industrial machinery where both properties are needed.

Q 3. What thread size and dimensions does this buffer have?

A. The 5040FFB10-60 has a 50 mm diameter, 40 mm height, and a female M10 threaded insert for direct mounting to equipment frames or structures.

Q 4. What types of equipment and industries is this buffer suited to?

A. This buffer is appropriate for construction equipment, industrial machinery, agricultural equipment, commercial vehicles, and power generation plant. It is also used in marine, railway, automotive and defence applications where controlled shock and vibration absorption are required.

Q 5. How does this buffer work to protect machinery?

A. The rubber-to-metal bonded construction absorbs and dissipates energy from impact shocks and vibration generated by external moving components or operating machinery. This reduces transmitted force to surrounding structures, improves machinery lifespan, and enhances operator comfort.

Q 6. Are other Shore hardness grades available in this 50 x 40 mm M10 size?

A. Yes. The same geometry is available as the 5040FFB10-45 for greater deflection and softer isolation at lower loads, and the 5040FFB10-70 for firmer support at higher loads with reduced movement. A wider range of face diameters and M16 threaded variants is also available.

Q 7. Are custom material or size options available for this buffer?

A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes. Contact us to discuss your requirements.
