Where machinery demands firm restraint and high load capacity, the 40x20mm Female Flat Buffer in 70 Shore A (SKU: 4020FFB10-70) delivers precisely that. With a maximum rated load of 327.0 kg and a deflection of just 5.00 mm under load, this rubber-to-metal bonded buffer is engineered for applications where minimal movement is critical and impact energy must be absorbed without give. The M10 female thread provides secure, direct fixing to structures and frames across many industrial plant. At 70 Shore A, this is the firmest grade in the flat buffer range, prioritising load-bearing integrity over deflection travel. The rubber-to-metal bonded construction ensures that shock and impact forces from external moving components are absorbed and dissipated efficiently, protecting surrounding structures and extending machinery service life. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request for demanding environments. This buffer is well suited to heavy industrial machinery, construction equipment, and commercial vehicle applications where components must be held firmly against shock loads or constrained with minimal compliance. It also finds use in agricultural equipment, power generation plant, and marine installations where high-load isolation points are required at standard mounting centres. Loaded in compression, shear, or a combination of both, the 40x20mm format covers mainstream mounting requirements at the firm end of the hardness range.

A. This 70 Shore A Female Flat Buffer is rated to a maximum load of 327.0 kg with a deflection of 5.00 mm, making it the firmest option in the 40x20mm M10 range.
A. At 70 Shore A, this is the firmest grade available in this geometry. It is designed to carry higher loads with minimal movement, making it suitable for applications requiring firm restraint, impact absorption, or shock resistance rather than high deflection or vibration isolation.
A. This firm-grade buffer is suited to heavy industrial machinery, construction equipment, commercial vehicles, agricultural equipment, power generation plant, and marine installations where components must be held securely against shock or high compressive loads.
A. The buffer uses an M10 female thread for direct fixing to structures or frames. It may be loaded in compression, shear, or a combination of both depending on the application.
A. Yes. The same 40x20mm M10 geometry is available in 45 Shore A (4020FFB10-45) for greater deflection and lighter duties, and 60 Shore A (4020FFB10-60) as a mid-hardness option. Select the grade that best matches your load and isolation requirements.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request, as are additional and custom sizes.
A. We accept all major credit and debit cards, along with PayPal.
