Where a mounting application demands neither maximum isolation nor maximum restraint, the 40x20mm Female Flat Buffer in 60 Shore A rubber, sKU 4020FFB08-60. Occupies the productive middle ground, rated to a maximum load of 238.0 kg with a controlled deflection of 5.00 mm at the M8 female thread. This makes it well suited to mainstream general-machinery mounting across moderate-load duty cycles, where consistent support and adequate vibration attenuation are both required. Constructed with rubber-to-metal bonding throughout, the buffer absorbs and dissipates energy on contact with a secondary moving component or surface. The 60 Shore A hardness grade delivers the balanced performance characteristic of a medium-compound mount: enough compliance to attenuate vibration and cushion impact shocks, yet sufficient stiffness to maintain positional control under the 238.0 kg rated load. Deflection is held to 5.00 mm, giving predictable, repeatable behaviour across service life. Stainless steel metal inserts and oil-resistant or high-temperature rubber compounds are available on request for demanding environments. This buffer is used across a broad spread of industries and equipment types. Typical applications include industrial machinery, agricultural equipment, construction and off-highway plant, commercial vehicles, and power-generation equipment. The M8 female thread provides direct bolt-in fitment to machine frames and sub-assemblies, and the flat-face geometry allows loaded contact in compression or in combination with shear loading.

A. This buffer is rated to a maximum load of 238.0 kg with a deflection of 5.00 mm. The M8 female thread and 40x20mm body dimensions are designed for moderate-load general-machinery mounting duties.
A. 60 Shore A is a medium rubber hardness. It provides a balance between vibration isolation and load-bearing support — offering sufficient compliance to cushion impact shocks and attenuate vibration, while maintaining the stiffness needed to control movement at the rated 238.0 kg load with 5.00 mm deflection.
A. It is suitable for industrial machinery, agricultural equipment, construction and off-highway plant, commercial vehicles, and power-generation equipment — wherever moderate-load mounting with balanced isolation and support is required.
A. The M8 female thread allows direct bolt-in mounting to machine frames and sub-assemblies. The buffer can be loaded in compression, shear, or a combination of both, depending on the application.
A. The 40x20mm M8 Female Flat Buffer is also available in 45 Shore A (SKU: 4020FFB08-45) for greater deflection and better isolation at lower loads, and in 70 Shore A (SKU: 4020FFB08-70) for higher load capacity with reduced movement.
A. Yes — stainless steel metal inserts and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes. Contact PartsForMachines to discuss your requirements.
