Product Number: 4030FFB10-70
Variations
Engineered to hold firm under serious load, the Female Flat Buffer 4030FFB10-70 is a 40 x 30 mm rubber-to-metal bonded buffer with an M10 female thread and a 70 Shore A hardness rating, the firmest grade in this geometry, rated to a maximum load of 248.0 kg with a controlled deflection of just 7.50 mm. Where heavier forces, shock events, or the need to restrain component movement demand a buffer that yields as little as possible, this grade is the specified choice. The rubber-to-metal bonded construction ensures the elastomeric element remains captive under load, transmitting compressive and shear forces through the mount without risk of separation. At 70 Shore A, the rubber compound resists deformation far more than the softer 45 or 60 Shore grades in this family, making it well suited to applications where positional control and high load-bearing are priorities alongside impact cushioning. Energy is absorbed and dissipated through the rubber mass rather than transferred destructively into the surrounding structure, protecting both the machine and its supporting framework. This buffer serves industries and equipment where duty cycles are demanding: construction and off-highway machinery, agricultural equipment, commercial vehicles, power generation plant, and marine and railway installations. It is particularly appropriate where a secondary object strikes the buffer under significant force, or where the mount must act as an elastic end-stop, limiting travel and absorbing shock at the extreme of movement.

A. The 4030FFB10-70 Female Flat Buffer is rated to a maximum load of 248.0 kg with a deflection of 7.50 mm at that load.
A. A 70 Shore A rating indicates a firm rubber compound. Compared with softer grades in this geometry, the 70 Shore A buffer carries higher loads with less deflection, making it the appropriate choice where movement must be minimised and shock forces are substantial.
A. The buffer has a female M10 thread and measures 40 mm in diameter by 30 mm in height.
A. This buffer is suited to construction and off-highway equipment, agricultural machinery, commercial vehicles, power generation plant, marine installations, and railway and mass transit applications — anywhere a firm end-stop or high-load vibration buffer is required.
A. The rubber-to-metal bonded construction allows the elastomeric element to absorb and dissipate energy from impact or vibration, reducing the force transmitted to the surrounding structure and improving machinery lifespan and operator comfort.
A. Yes — the same geometry is available in 45 Shore A (SKU 4030FFB10-45) and 60 Shore A (SKU 4030FFB10-60) for applications requiring greater deflection or improved isolation at lower loads.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes beyond the standard range.
