Rated at a maximum load of 287.0 kg with a controlled deflection of just 6.25 mm, this 40 x 25 mm Female Flat Buffer with M8 thread is engineered for applications where rubber mounts must hold firmly under heavy load and resist movement under impact, the 70 Shore A hardness grade is the firmest in the 40 x 25 mm flat buffer family, and the right choice when cushioning must not become compliance. The rubber-to-metal bonded construction ensures the elastomeric element remains securely anchored to the metal insert throughout its working life, maintaining consistent performance under repeated shock and compressive loading. The flat buffer geometry works in compression and shear, absorbing and dissipating energy from external moving components to protect adjacent structures and extend machinery service life. At 70 Shore A, the rubber compound delivers its energy absorption while minimising axial travel, making these units well-suited to heavier industrial machinery, construction equipment, agricultural plant and commercial vehicles, applications where a mount must carry substantial weight and resist displacement rather than offer soft, low-frequency isolation. Dimensions of 40 mm diameter by 25 mm height with an M8 female thread permit straightforward bolted installation. Custom variants with stainless steel metalwork or oil-resistant and high-temperature rubber compounds are available on request for demanding environments. This SKU is the 70 Shore A option within the 40 x 25 mm / M8 range; softer isolation grades are available as 4025FFB08-45 and 4025FFB08-60.

A. This Female Flat Buffer is rated to a maximum load of 287.0 kg and has a deflection of 6.25 mm.
A. At 70 Shore A, this is the firmest grade in the 40 x 25 mm flat buffer family. The harder compound carries higher loads with less movement, making it the appropriate choice where a mount must resist displacement under heavy or repeated impact loading rather than provide soft, high-deflection isolation.
A. The buffer measures 40 mm diameter by 25 mm height and features an M8 female thread for bolted installation.
A. Female Flat Buffers of this type are used across construction and off-highway equipment, industrial machinery, agricultural plant, commercial vehicles, elevators, power generation, marine, railway and mass transit, automotive, and military and defence applications.
A. The rubber-to-metal bonded construction works by absorbing and dissipating energy from external moving components. The unit may be loaded in compression, shear, or a combination of both, cushioning impacts and reducing transmitted force to protect surrounding structures and improve operator comfort.
A. Yes. The 40 x 25 mm M8 Female Flat Buffer is available in 45 Shore A (4025FFB08-45) and 60 Shore A (4025FFB08-60). Softer grades provide greater deflection and better isolation at lower loads; this 70 Shore A grade carries the highest load with the least movement in the family.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes.
