Engineered for maximum vibration isolation at moderate loads, this 50 x 20 mm male flat buffer with M10 x 28 stud (SKU 5020MFB28-45) is rated to a maximum load of 343.0 kg and delivers 5.0 mm of deflection, characteristics that make it particularly well suited to lighter or vibration-sensitive equipment where energy absorption and low-frequency isolation take priority over restraint. At 45 Shore A, the softer rubber compound yields greater movement under load, giving this variant its isolation advantage within the standard load band of the flat buffer range. Male flat buffers of this type work by absorbing and dissipating impact energy, cushioning machinery against shock from external moving components and reducing transmitted force. Rubber-to-metal bonded construction ensures structural integrity across the working load range, while the single-stud male configuration allows straightforward installation without specialist tooling. The 45 Shore A grade is the correct choice where the priority is compliance and deflection rather than stiffness. Applications well matched to this grade's deflection characteristics include construction equipment, agricultural machinery, industrial plant, elevators, and commercial vehicles operating at lower dynamic load cycles. Industries served by this buffer family include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence. Correct grade selection, softer for isolation, harder for higher load and reduced movement. Is central to achieving the intended performance. This buffer is available in two additional hardness grades: 60 Shore A (5020MFB28-60) and 70 Shore A (5020MFB28-70).

A. The buffer has an outer diameter and height of 50 x 20 mm, an M10 x 28 stud, a maximum load rating of 343.0 kg, and a deflection of 5.0 mm under load.
A. At 45 Shore A, the rubber is softer and delivers greater deflection — 5.0 mm — under the rated load. This makes it the appropriate choice for lighter or vibration-sensitive equipment and applications where low-frequency vibration isolation is more critical than stiffness or load restraint. Harder grades carry higher loads with less movement and suit applications where rigidity and shock restraint are the priority.
A. Male flat buffers are used across construction equipment, industrial machinery, agricultural equipment, elevators, and commercial vehicles. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. It works by absorbing and dissipating the energy of an impact or vibration event. The rubber element cushions machinery against shock from external moving components or acts as an elastic element in direct contact with a surface, reducing transmitted force and protecting surrounding structures. The rubber-to-metal bonded construction maintains integrity across the working load range.
A. The 50 x 20 mm M10 x 28 flat buffer is also available in 60 Shore A (5020MFB28-60) and 70 Shore A (5020MFB28-70). The wider male flat buffer range includes 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44. Custom sizes and materials are available on request.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds, along with additional and custom sizes, are available on request.
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.
