Product Number: 4020MFB23-60
Variations
Balancing isolation performance with load-bearing capability, the 40x20mm Male Flat Buffer at 60 Shore A (SKU: 4020MFB23-60) occupies the mainstream centre of the range, engineered for the broad middle ground where moderate loads and controlled deflection are equally important. With a maximum load rating of 233.0 kg and a deflection of 5.0 mm, this medium-grade buffer delivers the measured compliance that general-machinery mounting demands without sacrificing positional stability under working loads. The rubber-to-metal bonded construction gives the 4020MFB23-60 its characteristic balance: the 60 Shore A rubber resists excessive movement under load whilst still absorbing and dissipating the energy of recurring impact shocks from external moving components. The M8 x 23 mm male stud allows straightforward installation, and the flat-top geometry places the rubber face in direct contact with a surface, making it effective both as a shock buffer and as an elastic element in machinery assemblies. At this hardness grade, the buffer is well suited to industrial machinery, commercial vehicles, agricultural equipment, and construction equipment where sustained moderate loads coincide with intermittent shock events. Applications across power generation, marine, and railway and mass transit plant also fall within the operating envelope that 60 Shore A addresses most effectively. The ability to accept loading in compression, shear, or a combination of both extends its usefulness across a wide variety of mounting configurations in these sectors. For lighter-duty or high-isolation applications, the 45 Shore A variant (4020MFB23-45) provides greater deflection at lower load.
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 4020MFB23-60 has a diameter and height of 40 x 20 mm, a male stud thread of M8 x 23 mm length, a maximum load rating of 233.0 kg, and a deflection of 5.0 mm. The rubber is 60 Shore A hardness.
A. The 60 Shore A hardness grade is well suited to general-purpose machinery mounting in industrial machinery, construction equipment, agricultural equipment, commercial vehicles, and power generation plant, where moderate sustained loads and intermittent shock absorption are both required.
A. Within the 40x20mm Male Flat Buffer range, the 45 Shore A variant (4020MFB23-45) offers greater deflection and better isolation at lower loads, while the 70 Shore A variant (4020MFB23-70) carries higher loads with less movement. The 60 Shore A grade balances isolation performance and load support for general-machinery applications.
A. The rubber-to-metal bonded construction of the Male Flat Buffer allows it to be loaded in compression, shear, or a combination of both, accommodating a range of mounting configurations.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes beyond those listed in the standard range.
A. The range includes 4020MFB23-45, 4020MFB23-70, 4020MFB25-60, 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44, covering a variety of dimensional and load requirements.
