Q 1. What is the maximum load capacity of the 3017FFB08-70?

A. The 3017FFB08-70 Female Flat Buffer has a maximum load capacity of 175.0 kg.

Q 2. How much deflection does the 3017FFB08-70 produce under load?

A. The buffer deflects 4.25 mm at maximum rated load, making it the firmest option in the 30×17 mm M8 flat buffer range and the most appropriate choice where positional stability under load is a priority.

Q 3. What does a 70 Shore A hardness rating mean in practice?

A. A 70 Shore A rubber is a firm grade that carries higher loads with less movement than softer grades. It is best suited to heavier machinery, repeated shock and impact environments, and applications where the buffered component must be held firmly rather than allowed significant travel.

Q 4. What are the physical dimensions and thread specification of this buffer?

A. The buffer measures 30 mm diameter by 17 mm height (D × H: 30 × 17 mm) and is fitted with an M8 female thread.

Q 5. What applications is the 3017FFB08-70 designed for?

A. It is suited to general machinery mounting across construction equipment, industrial machinery, agricultural equipment, and commercial vehicles — particularly where moderate-to-heavy loads and shock or impact forces must be controlled with minimal movement.

Q 6. How does this buffer differ from the 45 Shore A and 60 Shore A variants in the same geometry?

A. All three share the 30×17 mm M8 female flat buffer geometry. The 45 Shore A (3017FFB08-45) provides the greatest deflection and best vibration isolation at lower loads; the 60 Shore A (3017FFB08-60) offers a balance of load capacity and deflection for general-purpose use; and the 70 Shore A (3017FFB08-70) carries the highest load with the least movement, prioritising shock containment and positional firmness.

Q 7. Are custom materials or sizes available for this buffer?

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

Q 8. How is the buffer loaded — compression, shear, or both?

A. The 3017FFB08-70 can be loaded in compression, shear, or a combination of both, depending on the installation geometry.

Q 9. What payment methods do you accept?

A. We accept all major credit and debit cards, along with PayPal.

Q 10. What payment methods do you accept?

A. We accept all major credit and debit cards, along with PayPal.
