Engineered for maximum vibration isolation, the 5021MFB25-45 is a 50 x 21 mm Male Flat Buffer with an M10 x 25 mm male stud, rated to a maximum load of 344.0 kg and a deflection of 5.3 mm at 45 Shore A hardness. At the softer end of this geometry's hardness range, this grade delivers the greatest deflection under load, making it well suited to lighter or vibration-sensitive equipment where isolation from low-frequency disturbance takes priority over restraint or high-load rigidity. Constructed with a rubber-to-metal bonded design, the flat buffer profile provides low-cost shock and vibration absorption with straightforward installation. The soft 45 Shore A rubber compound yields readily under load, absorbing and dissipating energy efficiently to reduce impact force transmitted either from a secondary moving component or through direct contact with a surface. This compliance also contributes to improved operator comfort and helps protect surrounding structures from repeated shock loading. The 50 x 21 mm format with M10 stud suits mainstream general-machinery mounting duties at moderate loads, particularly where the primary objective is isolating sensitive equipment from structurally transmitted vibration. Typical applications include agricultural machinery, power generation plant, commercial vehicles and industrial equipment operating in construction and off-highway environments. The buffer may be loaded in compression, shear, or a combination, broadening its practical scope across these sectors. Custom variants in oil-resistant or high-temperature rubber, stainless steel metalwork, and additional sizes are available on request.

A. The buffer measures 50 mm diameter by 21 mm height, with an M10 x 25 mm male stud. It has a maximum load rating of 344.0 kg and a deflection of 5.3 mm.
A. At 45 Shore A, this is the softest grade in the 50 x 21 mm Male Flat Buffer range. Softer grades yield greater deflection under load, which delivers better vibration isolation — particularly at lower frequencies — and is best suited to lighter or vibration-sensitive equipment where absorption takes priority over load restraint.
A. This buffer is suited to agricultural machinery, power generation plant, commercial vehicles, industrial machinery, construction and off-highway equipment, and any application requiring absorption of impact shocks or isolation from structurally transmitted vibration at moderate loads.
A. The buffer absorbs and dissipates energy through its rubber compound, reducing impact force transmitted from a secondary moving component or through direct contact with a surface. The rubber-to-metal bonded construction allows it to be loaded in compression, shear, or a combination of both.
A. Yes — the same Male Flat Buffer geometry is available in 60 Shore A (SKU: 5021MFB25-60) and 70 Shore A (SKU: 5021MFB25-70). Harder grades carry higher loads with less movement; the 45 Shore A grade offers the greatest deflection and isolation performance.
A. Yes — stainless steel metalwork, oil-resistant rubber, high-temperature rubber compounds, and additional or custom sizes are available on request.
