Product Number: 5040MFB25-70
Carrying a maximum load of 349.0 kg with a controlled deflection of just 10.0 mm, the 5040MFB25-70 is a 50 x 40 mm male flat buffer rated at 70 Shore A, the firm grade in this geometry, selected where machinery must be held securely against heavy loads, shock forces, or sustained impact rather than simply isolated from vibration. The M10 x 25 stud gives a direct, positive fixing into the host structure without secondary hardware. Rubber-to-metal bonded construction is the defining feature of this buffer's durability: the vulcanised bond prevents delamination under repeated compressive and shear loading, while the flat face maximises contact area for even load distribution. At 70 Shore A, the rubber compound resists excessive deflection under high load, making the mount effective as a restraint element or hard stop as well as an energy-absorbing cushion. The low-cost, straightforward geometry makes installation accessible in confined or awkward locations where a more complex mount would not fit. In service, the 5040MFB25-70 absorbs and dissipates impact energy rather than transmitting shock through a frame, protecting surrounding structures and improving the working life of connected components. Applications that suit this firm grade include construction and off-highway equipment subject to ground-transmitted shock, commercial vehicles where body panels or sub-frames require positive location, industrial machinery on production lines handling heavy workpieces, and agricultural equipment exposed to sustained vibration at higher load cycles. Power generation, marine, and railway environments are further fields where the hardness grade supports reliable performance under demanding duty.

A. The 5040MFB25-70 is rated to a maximum load of 349.0 kg with a deflection of 10.0 mm, making it the firm option in the 50 x 40 mm male flat buffer range.
A. The buffer body measures 50 mm diameter by 40 mm height (D x H: 50 x 40). The male stud is M10 with a 25 mm shank length (d x L: M10 x 25).
A. At 70 Shore A, the rubber carries higher loads with less movement than softer grades. This makes it the preferred choice when the mount must resist heavy or shock loading, act as a positive restraint, or prevent excessive displacement — rather than prioritising isolation at lighter loads.
A. The 5040MFB25-70 is suited to construction and off-highway equipment, commercial vehicles, heavy industrial machinery, agricultural equipment, and power generation or marine plant where firm support under sustained or impact loading is required.
A. The buffer absorbs and dissipates energy from an impacting or vibrating component, reducing the shock force transmitted to the host structure. The rubber-to-metal bonded construction maintains integrity under repeated compressive and shear loading.
A. Yes — the 50 x 40 mm male flat buffer is also offered in 45 Shore A (5040MFB25-45) and 60 Shore A (5040MFB25-60). Alternative footprint sizes include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
A. Stainless steel hardware and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes. Contact the team to discuss your specific requirements.
