Q 1. What are the key dimensions and load ratings for the 4028MFB23-60?

A. The buffer measures 40 mm diameter by 28 mm height, with an M8 x 23 mm threaded stud. Maximum rated load is 184.5 kg, and controlled deflection is 6.8 mm.

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

A. At 60 Shore A, this is the medium grade of the range. It provides a balanced combination of vibration isolation and load-bearing support, making it well suited to general-machinery mounting at moderate loads where neither maximum compliance nor maximum stiffness is required.

Q 3. What industries and applications is the 4028MFB23-60 suitable for?

A. The buffer is designed for use across industrial machinery, agricultural equipment, commercial vehicles, power-generation plant, and construction equipment — any application where controlled absorption of vibration and impact shock at moderate loads is needed.

Q 4. How does this buffer work and what loading modes does it accept?

A. The rubber-to-metal bonded construction absorbs and dissipates energy when the buffer is loaded. It can be used in compression, shear, or a combination of both, cushioning machinery against impact shocks and reducing transmitted vibration to surrounding structures.

Q 5. What other Shore hardness grades are available in this 40 x 28 mm flat buffer?

A. This size is also available in a 45 Shore A softer grade (4028MFB23-45), which provides greater deflection and enhanced isolation at lower loads, and in a 70 Shore A firmer grade (4028MFB23-70), which carries higher loads with less movement.

Q 6. Are custom materials or sizes available for this flat 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 7. What payment methods do you accept?

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

Q 8. How long does delivery take?

A. Standard UK mainland delivery is 3–5 working days. Next-day delivery is available on most products and will appear as an option at checkout where eligible.
