Where maximum vibration isolation takes priority over restraint, the 40x28mm Female Flat Buffer in 45 Shore A rubber (SKU: 4028FFB10-45) is the softest grade in the 40x28mm flat buffer range, rated to a maximum load of 127.0 kg with a deflection of 7.00 mm. That generous deflection is the defining characteristic of this grade: the rubber yields readily under load, absorbing and dissipating energy efficiently at the lower end of the load band and making this the natural choice where isolating delicate or sensitive equipment from vibration matters more than limiting movement. Constructed with rubber-to-metal bonding throughout, this female flat buffer is designed to cushion machinery against impact shocks from external moving components. The M10 female thread suits many fixing arrangements, and the 40 mm diameter keeps the footprint compact. The soft 45 Shore A compound delivers the greater deflection characteristic of softer grades, providing superior isolation of lower-frequency vibration and protecting both the host machine and surrounding structures from transmitted shock. This grade suits lighter or compact installations across construction equipment, agricultural machinery, industrial plant, and commercial vehicles where operator comfort and equipment protection are paramount. It also finds use in elevators and power generation applications. Improving machinery lifespan and reducing shock transmission to surrounding structures are consistent benefits across the application range. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for demanding environments.

A. The buffer measures 40 mm diameter by 28 mm height with an M10 female thread. It is rated to a maximum load of 127.0 kg with a deflection of 7.00 mm.
A. Softer grades such as 45 Shore A give greater deflection under load and deliver better vibration isolation, particularly at lower frequencies and lighter loads. Where isolating sensitive or compact equipment from vibration is the primary requirement, the softer compound is the appropriate choice. Harder grades carry higher loads with less movement but provide less isolation.
A. The buffer is designed for use on 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 applications.
A. The rubber-to-metal bonded construction absorbs and dissipates energy from impact shocks and vibration transmitted by external moving components. This cushioning action reduces impact forces, improves machinery lifespan, protects surrounding structures, and improves operator comfort.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes beyond the standard range.
A. The same 40x28mm M10 geometry is available in 60 Shore A (SKU: 4028FFB10-60) and 70 Shore A (SKU: 4028FFB10-70), offering progressively higher load capacity and reduced deflection for applications requiring greater restraint.
