Where vibration isolation takes priority over restraint, the 40×20mm Female Flat Buffer with M8 thread and 45 Shore A rubber compound delivers the compliance that lighter, sensitive, or low-frequency-loaded machinery demands. Rated to a maximum load of 158.0 kg with a deflection of 5.00 mm, this soft-grade mount is engineered to absorb and dissipate energy through maximum movement under load, the characteristic that makes it the natural choice when cushioning matters more than rigidity. Constructed using rubber-to-metal bonded technology, the buffer combines a vulcanised natural rubber element with a steel insert to ensure reliable, long-service performance under cyclic loading. The 45 Shore A hardness grade sits at the softer end of the flat buffer range, providing greater deflection per unit of applied force and superior attenuation of lower-frequency vibration. This softness is precisely what isolates sensitive instrumentation housings, agricultural machinery cabs, and light industrial equipment from the shock pulses and structural vibration that shorten component life and reduce operator comfort. The female M8 thread accepts standard metric fasteners, simplifying fitment to equipment frames and chassis without additional hardware. Loaded in compression, shear, or a combination of both, the 40×20mm body geometry suits panel-mount and flange-mount configurations across construction equipment, power generation plant, marine machinery, and commercial vehicle ancillaries. Mounts of this type act as an elastic element in direct contact with a surface, reducing impact force transmitted to surrounding structures and improving overall machinery lifespan.

A. This buffer is rated to a maximum load of 158.0 kg and provides 5.00 mm of deflection under load.
A. 45 Shore A is a soft rubber grade. Softer grades give greater deflection under load and better vibration isolation, particularly at lower frequencies. This makes the 4020FFB08-45 most suitable for lighter or sensitive equipment where isolation performance takes priority over load restraint.
A. The buffer has a female M8 metric thread, which accepts standard M8 fasteners for straightforward fitment to equipment frames and chassis.
A. The buffer measures 40 mm in diameter and 20 mm in height (D × H: 40 × 20 mm).
A. Female flat buffers of this type are used across construction equipment, agricultural machinery, industrial machinery, commercial vehicles, elevators, power generation plant, and marine applications. The 45 Shore A soft grade is particularly suited to lighter or vibration-sensitive installations in these sectors.
A. The rubber-to-metal bonded construction absorbs and dissipates energy from shock and vibration inputs, reducing the impact force transmitted to surrounding structures, improving machinery lifespan, and contributing to operator comfort.
A. Yes. This 40×20mm M8 body is also available in 60 Shore A (4020FFB08-60) and 70 Shore A (4020FFB08-70) for heavier or more dynamic loading. Larger body variants include 100100FFB16, 10030FFB16, 10040FFB16, 10050FFB16, 10055FFB16, and 10060FFB16. Custom sizes, stainless steel metalwork, and specialist rubber compounds are available on request.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
