Engineered for maximum vibration isolation under moderate loads, the Female Flat Buffer 40x20mm M10 45 Shore A (SKU: 4020FFB10-45) delivers the greatest deflection and energy absorption within the 40x20mm flat-buffer family. At 45 Shore A, this is the softest grade available in this geometry, a deliberate design choice that allows up to 5.00mm of deflection under its rated maximum load of 158.0kg, making it the preferred option wherever isolation performance takes priority over rigid restraint. The rubber-to-metal bonded construction pairs a soft natural rubber element with a threaded M10 female insert, allowing direct bolt-down fitment to machinery frames, chassis members, or structural supports. At this hardness grade, the mount works by absorbing and dissipating impact and vibration energy with greater compliance, reducing transmitted shock to surrounding structures and improving operator comfort in applications where vibration sensitivity is highest. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request. The 45 Shore A grade is well suited to construction equipment, agricultural machinery, power generation plant, and commercial vehicles where lower-frequency vibration isolation is the primary requirement, and where the connected equipment or structure benefits from a softer, more compliant interface rather than a firm restraint. It is equally applicable in elevator installations and light industrial machinery where preserving sensitive components from transmitted shock is critical. This buffer is available in firmer grades for higher-load or higher-restraint duties: 60 Shore A (SKU: 4020FFB10-60) and 70 Shore A (SKU: 4020FFB10-70).

A. This buffer has a maximum load rating of 158.0kg and a deflection of 5.00mm, reflecting the high compliance of the 45 Shore A rubber grade.
A. Shore A hardness describes the softness of the rubber element. At 45 Shore A, this is the softest grade in the 40x20mm flat-buffer range, providing the greatest deflection under load and the best vibration isolation performance — particularly effective at lower frequencies and with lighter or more vibration-sensitive equipment.
A. The buffer uses an M10 female threaded insert, allowing direct bolt fitment to machinery frames, chassis members, or structural supports.
A. The female flat buffer suits construction equipment, agricultural machinery, industrial plant, elevators, commercial vehicles, power generation, and marine or railway applications where vibration damping and shock absorption are required.
A. The 45 Shore A grade (this SKU) gives the most deflection and best isolation at lower loads, making it the right choice where vibration sensitivity matters most. The 60 Shore A (4020FFB10-60) and 70 Shore A (4020FFB10-70) grades carry similar loads with progressively less movement, suiting applications requiring firmer restraint or higher stiffness.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request, as are additional and custom sizes.
