Product Number: 4040MFB25-60
Variations
Balancing deflection control with meaningful load capacity, the 4040MFB25-60 Male Flat Buffer occupies the broad middle ground of the range, rated to a maximum load of 145.5 kg with a controlled deflection of 10.0 mm at 60 Shore A hardness. Its 40 mm diameter by 40 mm height body carries an M10 x 25 mm stud, making it straightforward to install across a wide variety of mounting configurations where neither a soft-isolating nor a firm-restraining grade would be the natural fit. Constructed with rubber-to-metal bonding, the flat buffer format delivers low-cost shock and vibration absorption by absorbing and dissipating energy directly at the contact surface. At 60 Shore A, the rubber compound offers a calibrated balance between elastic compliance and structural support, responding effectively to combined shear and compression loading without the excessive movement of a softer grade or the reduced isolation of a firmer one. This makes it well suited to general-purpose industrial and commercial machinery where mounting conditions vary across a working day. The Male Flat Buffer design is widely applied across construction equipment, agricultural machinery, industrial plant, elevators and commercial vehicles. At this mid-range hardness, it is particularly appropriate for general industrial machinery mounting, power generation equipment, and agricultural applications where loads are moderate and consistent vibration management across a broad operating cycle is required.
Flat buffers are an economical and simple solution to absorbing shock and vibration. They are used mainly in compression and are available with various configurations. Additional sizes, rubber compounds and stainless-steel metals are all available on request.

A. The buffer measures 40 mm diameter by 40 mm height with an M10 x 25 mm male stud. It has a maximum load rating of 145.5 kg and a deflection of 10.0 mm.
A. Shore A hardness measures rubber stiffness. At 60 Shore A, this buffer sits at the mid-point of the range — softer grades give greater deflection and better isolation at lower loads, while harder grades carry higher loads with less movement. The 60 Shore A grade suits general-purpose machinery mounting where a balance of elastic compliance and load support is needed.
A. The male flat buffer is used across construction equipment, industrial machinery, agricultural equipment, elevators and commercial vehicles. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. The rubber-to-metal bonded construction absorbs and dissipates impact energy when an external moving component contacts the buffer face. It can be loaded in shear, compression, or a combination of both, cushioning impact shocks, reducing transmitted force to surrounding structures, and improving operator comfort and machinery lifespan.
A. Yes. The same 40 x 40 mm M10 x 25 geometry is available in 45 Shore A (4040MFB25-45) and 70 Shore A (4040MFB25-70). Additional sizes in the male flat buffer range include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41 and 10055MFB44.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available, as are additional and custom sizes, on request.
