Q 1. What are the load and deflection ratings for the 5040MFB25-60?

A. This buffer has a maximum load rating of 252.0 kg and a deflection of 10.0 mm, making it suitable for moderate-load general machinery mounting applications.

Q 2. What does 60 Shore A hardness mean for this buffer?

A. At 60 Shore A, this buffer sits at the mid-range of hardness, offering a balance between vibration isolation and load support. Softer grades provide greater deflection and better isolation at lower loads; harder grades carry higher loads with less movement. The 60 Shore A grade is appropriate for mainstream general-machinery mounting at moderate loads.

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

A. The buffer body measures 50 mm diameter by 40 mm height (D x H: 50 x 40 mm). The male threaded stud is M10 with a 25 mm stud length (d x L: M10 x 25 mm).

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

A. This buffer is suitable for industrial machinery, agricultural equipment, construction equipment, commercial vehicles and elevators. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.

Q 5. How does a Male Flat Buffer work?

A. Male Flat Buffers use rubber-to-metal bonded construction to absorb and dissipate energy from impact shocks generated by external moving components. They can act as a secondary shock-absorbing element or as a direct-contact elastic buffer against a surface, and may be loaded in shear, compression, or a combination of both.

Q 6. Are alternative hardness grades available in the same size?

A. Yes — the 50 x 40 mm / M10 x 25 mm format is also available in 45 Shore A (SKU: 5040MFB25-45) for greater deflection and lower-load isolation, and 70 Shore A (SKU: 5040MFB25-70) for higher load capacity with reduced deflection.

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

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

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.
