Product Number: 4020MFB23-45
Variations
Rated to a maximum load of 155 kg with a deflection of 5.0 mm, this 40×20 mm male flat buffer (SKU 4020MFB23-45) offers a 45 Shore A rubber compound specifically chosen where vibration isolation takes priority over load restraint. At the softer end of the hardness scale, the 45 Shore A grade yields the greatest deflection within this geometry and delivers the most effective energy dissipation at lower loads, making it the preferred selection for lighter or sensitive equipment where minimising transmitted vibration matters most. Constructed with rubber-to-metal bonding throughout, the buffer works by absorbing and dissipating impact energy, reducing the force transferred from a secondary moving component to the host structure. The flat-face male stud configuration, m8 thread, 23 mm stud length. Allows straightforward installation into tapped housings without the need for specialist tooling. The soft-grade rubber compound responds readily to lower-frequency excitation, cushioning intermittent contact loads and acting as an elastic element in direct contact with a surface where other mount geometries would offer too little compliance. Application areas supported by the source data include construction and off-highway equipment, industrial machinery, agricultural equipment, elevators, and commercial vehicles. The 45 Shore A rating suits roles in power generation, marine, and railway environments where the priority is operator comfort and protection of surrounding structures rather than high-load restraint. Custom options, including oil-resistant or high-temperature rubbers and stainless steel metalwork. Are available on request. This buffer is part of a broader male flat buffer range.

A. The 4020MFB23-45 has a maximum load rating of 155 kg and a deflection of 5.0 mm under that load, making it suitable for lighter or moderate-load applications where vibration isolation is the primary requirement.
A. A 45 Shore A rating places this buffer at the softer end of the hardness scale for this geometry. Softer grades give greater deflection under load and deliver better vibration isolation at lower loads, making this grade ideal where reducing transmitted vibration and protecting sensitive equipment takes precedence over carrying high loads or limiting movement.
A. The buffer has an outer diameter of 40 mm and a height of 20 mm. The male stud is M8 with a stud length of 23 mm.
A. The male flat buffer range is suited to construction and off-highway equipment, industrial machinery, agricultural equipment, elevators, commercial vehicles, power generation, marine applications, and railway and mass transit environments. The 45 Shore A soft grade is particularly well matched to lighter or sensitive equipment where isolation from lower-frequency vibration is critical.
A. The buffer works by absorbing and dissipating impact energy from external moving components. The flat-face rubber element cushions contact loads and can act as an elastic element in direct contact with a surface, reducing the force transferred to the host structure and improving machinery lifespan and operator comfort.
A. Yes. The 40×20 mm M8 platform is also available in 60 Shore A (SKU 4020MFB23-60) and 70 Shore A (SKU 4020MFB23-70). Additional geometries within the male flat buffer family include SKUs 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44. Custom sizes, stainless steel metalwork, and oil-resistant or high-temperature rubber compounds are also available on request.
