Variations
Engineered for maximum vibration isolation, this 75 x 50 mm male flat buffer with M12 x 37 mm stud offers a 45 Shore A rubber hardness that delivers the greatest deflection and compliance within the range, rated to a maximum load of 495.0 kg with a deflection of 12.50 mm. At this soft grade, the rubber yields more readily under load, prioritising energy absorption and isolation over restraint, which makes this buffer particularly well suited to lighter or vibration-sensitive equipment where minimising transmitted vibration matters more than limiting movement. Rubber-to-metal bonded construction gives the unit structural integrity while the low-profile flat geometry keeps installation straightforward. The male thread allows direct engagement without special tooling, and the buffer's working principle, absorbing and dissipating shock energy on contact with a secondary surface. Means it can function equally well as a bump stop against an impacting component or as a compliant mounting element in sustained contact with a surface. The 45 Shore A grade is the softest in the flat buffer family, and as the source confirms, softer grades provide better isolation at lower loads and improve operator comfort alongside protecting surrounding structures. This buffer finds strong application across lower-frequency isolation scenarios in agricultural equipment, elevators, and light industrial machinery, as well as in power generation and marine environments where surface-borne vibration needs to be decoupled rather than absorbed under high restraint force.

A. This buffer is rated to a maximum load of 495.0 kg and provides a deflection of 12.50 mm at that load.
A. A 45 Shore A rating indicates a soft rubber compound. Softer grades give greater deflection under load and deliver better vibration isolation, particularly at lower loads and lower frequencies. This makes the 45 Shore A grade the most compliant option in the flat buffer range, prioritising isolation over movement restraint.
A. Male flat buffers in the 45 Shore A grade are well suited to agricultural equipment, elevators, light industrial machinery, power generation, and marine applications — anywhere vibration isolation and energy absorption matter more than high-load restraint. They can be used as bump stops against moving components or as elastic contact elements on stationary surfaces.
A. The outer diameter and height are 75 x 50 mm. The male stud is M12 with a length of 37 mm.
A. It uses rubber-to-metal bonded construction. The buffer works by absorbing and dissipating energy on contact, and can be loaded in compression, shear, or a combination of both depending on the installation.
A. Yes. This 75 x 50 mm male flat buffer is available in 60 Shore A (7550MFB37-60) and 70 Shore A (7550MFB37-70) for higher-load or lower-deflection applications. Additional sizes include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
A. Yes. Stainless steel hardware and oil-resistant or high-temperature rubber compounds, along with additional and custom sizes, are available on request.
