Product Number: 4020MFB25-60
Variations
Balancing load capacity with controlled deflection, the Male Flat Buffer 4020MFB25-60 is a 40x20mm rubber-to-metal bonded mount rated to a maximum load of 233.0 kg with a deflection of 5.0 mm at 60 Shore A hardness, a medium grade suited to the broad middle ground of general machinery mounting where neither maximum isolation nor maximum rigidity is the priority. At 60 Shore A, this buffer occupies the mid-range of the hardness spectrum, delivering a practical balance between vibration isolation and structural support. The rubber-to-metal bonded construction ensures secure energy absorption under moderate operating loads, cushioning machinery against impact shocks from external moving components while protecting surrounding structures and improving operator comfort. The M10 x 25 male stud fixing makes installation straightforward without specialist tooling. Designed to absorb and dissipate energy under compression, shear, or combined loading, this flat buffer is well matched to mainstream industrial and agricultural applications where loads are moderate and consistent. Typical service environments include industrial machinery, construction equipment, agricultural equipment, commercial vehicles, and elevators. The geometry also finds use in power generation, marine, railway and mass transit, and automotive sectors. Where oil-resistant or high-temperature rubber compounds are needed, or stainless steel metalwork is required, custom options are available on request. For alternative hardness grades in this 40x20mm M10 geometry, see the 45 Shore A grade (4020MFB25-45) for softer isolation duty or the 70 Shore A grade (4020MFB25-70) for higher-load applications.

A. The buffer measures 40mm diameter by 20mm height (D x H) with an M10 x 25mm male stud (d x L). It has a maximum load rating of 233.0 kg and a deflection of 5.0 mm.
A. 60 Shore A is a medium hardness grade that provides a balance between vibration isolation and load support. Compared with softer grades, it carries higher loads with less movement; compared with harder grades, it offers greater deflection and better isolation. It is suited to general-purpose machinery mounting at moderate loads.
A. This buffer is suited to industrial machinery, construction equipment, agricultural equipment, commercial vehicles, and elevators. It also serves power generation, marine, railway and mass transit, automotive, and military and defence applications.
A. The rubber-to-metal bonded construction absorbs and dissipates energy from impact shocks and vibration. It can be loaded in compression, shear, or a combination of both, cushioning machinery against contact with external moving components, protecting surrounding structures, and improving operator comfort.
A. Yes. The same 40x20mm M10 x 25 flat buffer is available in 45 Shore A (4020MFB25-45) for softer isolation duty and 70 Shore A (4020MFB25-70) for higher-load, lower-deflection applications.
A. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes. Contact us to discuss your requirements.
