Variations
Sensitive installations and lighter machinery demand vibration control that prioritises isolation over restraint, and the 40x40mm Male Flat Buffer at 45 Shore A is engineered precisely for that role. This soft-grade rubber-to-metal bonded buffer carries a maximum load of 97.0 kg with a deflection of 10.0 mm under load, characteristics that make it well suited to applications where compliance and energy absorption across a broad frequency range are more important than rigid damping. The M8 x 23 mm threaded stud allows fast, tool-accessible installation without the need for secondary fixings. The flat buffer geometry works by absorbing and dissipating impact energy directly between a surface and the mounted component, functioning as an elastic element in shear, compression, or a combination of both loading conditions. At 45 Shore A, the rubber compound yields more readily under load than harder grades, delivering greater deflection and better vibration isolation at the lower load ranges typical of compact sub-assemblies, control panels, lightweight agricultural equipment, and elevator guide components where transmitted shock must be minimised. Across the industries this design serves, construction and off-highway machinery, power generation, marine installations, and automotive applications. The soft grade finds its place wherever operator comfort and the protection of sensitive surrounding structures take precedence. Its low-cost, easy-fit design makes it a practical first-choice component for reducing impact force from secondary moving objects or cushioning direct contact surfaces. This SKU is the soft-grade variant within the 40x40mm Male Flat Buffer family.

A. The buffer measures 40 mm diameter by 40 mm height, with an M8 x 23 mm threaded stud. Maximum load is 97.0 kg and deflection under load is 10.0 mm.
A. At 45 Shore A, this is the softest grade in the 40x40mm Male Flat Buffer family. Softer grades yield greater deflection under load and provide better vibration isolation at lower load levels, making this grade the right choice where isolating sensitive equipment from vibration or impact is more important than limiting movement.
A. It is well suited to lighter or compact installations where isolation from vibration and impact shock is the priority — including agricultural equipment, elevator components, light industrial machinery, and automotive assemblies where transmitted vibration or impact must be minimised and loads fall within the 97.0 kg maximum.
A. The rubber-to-metal bonded construction allows the rubber element to work in compression, shear, or a combination of both, absorbing and dissipating energy from impacts or vibration generated by secondary moving components. This reduces the force transmitted to the mounting structure and surrounding equipment.
A. Yes. The same 40x40mm M8 geometry is available in 60 Shore A (4040MFB23-60) and 70 Shore A (4040MFB23-70) for higher-load or greater-restraint applications. Additional Male Flat Buffer sizes include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
A. Yes. Stainless steel metalwork, oil-resistant rubber, high-temperature rubber compounds, and custom or additional sizes are available on request.
