Variations
Prioritising maximum vibration isolation over restraint, this 75 x 55 mm Male Flat Buffer with M12 x 37 stud thread is engineered for applications where absorbing and dissipating low-frequency shock energy matters most. At 45 Shore A, the softest grade in this geometry's range. It yields up to 13.76 mm of deflection under a maximum load of 427.0 kg, making it the appropriate selection where equipment is sensitive, lighter-duty, or where isolating the structure from vibration takes precedence over restricting movement. Rubber-to-metal bonded construction gives the buffer durability under cyclic loading whilst maintaining the compliance that defines soft-grade performance. The flat-face geometry allows direct elastic contact with a secondary surface, cushioning impact forces from external moving components and reducing transmitted shock to surrounding structures. Low installation complexity is inherent in the male stud design, requiring no additional hardware beyond a standard M12 fixing point. Custom variants in oil-resistant or high-temperature rubbers and stainless steel metalwork are available on request. The 45 Shore A grade suits construction equipment, agricultural machinery, commercial vehicles, and industrial plant where operator comfort and protection of sensitive sub-assemblies are primary concerns. It also finds use in marine, power generation, and railway applications where lower-frequency excitation demands a compliant, high-deflection mount rather than a stiffer restraint element. Elevators and light off-highway equipment represent further typical installation environments.

A. The buffer measures 75 mm diameter by 55 mm height, with an M12 x 37 mm male stud. Maximum load rating is 427.0 kg and maximum deflection is 13.76 mm.
A. At 45 Shore A — the softest grade available in this geometry — the buffer provides greater deflection under load and superior isolation of low-frequency vibration. It is the correct choice when isolating sensitive or lighter equipment from shock and vibration takes priority over restricting movement or carrying higher static loads.
A. The 7555MFB37-45 is suited to construction equipment, agricultural machinery, industrial plant, commercial vehicles, elevators, and off-highway equipment. Industries served include construction, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. It uses rubber-to-metal bonded construction. The rubber element works by absorbing and dissipating energy from impact shocks or vibration transmitted by external moving components, reducing force transfer to the mounting structure and improving operator comfort and machinery lifespan.
A. Yes. The same 75 x 55 mm geometry is also available in 60 Shore A (7555MFB37-60) and 70 Shore A (7555MFB37-70). Additional Male Flat Buffer sizes in the range include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
A. Yes. Oil-resistant and high-temperature rubber compounds, stainless steel metalwork, and additional custom sizes are available on request.
A. We accept all major credit and debit cards, along with PayPal.
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.
