Product Number: 4040MFB25-45
Variations
Soft-grade vibration isolation is where the 4040MFB25-45 excels: a 40 x 40 mm rubber-to-metal bonded Male Flat Buffer threaded M10 x 25, rated to a maximum load of 97.0 kg with a deflection of 10.0 mm, purpose-built for applications where absorbing and dissipating energy matters more than load restraint. At 45 Shore A, this is the softest grade in the 40 x 40 mm flat buffer range, delivering maximum movement under load and the greatest vibration isolation of the family, particularly well suited where lower-frequency isolation and compliance take priority over stiffness. The rubber-to-metal bonded construction provides reliable attachment without additional hardware, and the male stud configuration makes installation straightforward on plant and equipment with mating threaded receivers. By absorbing impact energy rather than transmitting it, the buffer cushions machinery against shocks from external moving components and reduces force transferred to surrounding structures. This soft deflection characteristic makes it an appropriate choice for lighter or sensitive equipment where transmitted vibration must be kept to a minimum. Typical application areas include agricultural machinery, light industrial equipment, construction plant, commercial vehicles, elevators, and power generation equipment operating at lower load cycles. The buffer may be loaded in compression, shear, or a combination of both, and the family source confirms suitability across construction and off-highway, marine, railway and mass transit, automotive, and military and defence sectors. Custom options, including stainless steel metalwork and oil-resistant or high-temperature rubbers, plus additional and custom sizes. Are 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 97.0 kg and a deflection of 10.0 mm.
A. 45 Shore A is the softest grade in the 40 x 40 mm Male Flat Buffer range. Softer grades give greater deflection under load and deliver better vibration isolation, making this buffer the most compliant of the family and best suited to lighter or sensitive equipment and lower-frequency isolation applications.
A. The Male Flat Buffer family is suited to 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. It works by absorbing and dissipating energy from impact shocks and vibration. The rubber-to-metal bonded construction cushions machinery against shocks from external moving components, reduces impact force, and can act as an elastic element in direct contact with a surface, helping to improve machinery lifespan, protect surrounding structures, and improve operator comfort.
A. Yes — Male Flat Buffers may be loaded in shear, compression, or a combination of both, depending on the installation and application requirements.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubbers, plus additional and custom sizes, are available on request.
A. The 40 x 40 mm M10 x 25 Male Flat Buffer is available in 45 Shore A (4040MFB25-45), 60 Shore A (4040MFB25-60), and 70 Shore A (4040MFB25-70). Further sizes in the Male Flat Buffer family include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
