Product Number: 7040MFB25-70
Variations
Rated at a maximum load of 1,019 kg with a controlled deflection of just 10 mm, the 7040MFB25-70 is the firmest grade in the 70x40 mm male flat buffer range, engineered for applications where high shock forces must be absorbed without significant movement. The 70 Shore A rubber hardness grade makes this buffer the appropriate choice when machinery, vehicles or structures are subject to repeated heavy impact and the mounting point must remain positionally stable under load. Rubber-to-metal bonded construction joins the M10 x 25 mm male stud to a 70 mm diameter, 40 mm height rubber element. The flat buffer geometry works in direct contact with a surface or secondary object, absorbing and dissipating impact energy to protect the surrounding structure and reduce transmitted shock. At 70 Shore A, the rubber carries maximum load with least deflection within the family, suited to restraint and shock-duty roles where a softer grade would yield excessively. Typical deployment spans the heaviest-duty segments of the family's application range: construction equipment and off-highway plant subject to severe impact cycles, commercial and agricultural vehicles requiring firm bump-stop action, and industrial machinery installations in power generation or marine environments where load magnitude demands a firm elastic element. The male flat buffer format installs quickly and suits both compression and combined loading. This SKU is the 70 Shore A option of the 70x40 mm flat face size.

A. The 7040MFB25-70 has a maximum load rating of 1,019 kg with a deflection of 10 mm under that load.
A. The rubber element measures 70 mm diameter by 40 mm height (D x H). The male stud is M10 with a 25 mm length (d x L).
A. At 70 Shore A, this is the firmest grade available in the 70x40 mm flat buffer family. Harder rubber carries higher loads with less movement, making it the correct choice for heavy shock and impact duty or applications where the mounting point must be held firmly. Softer grades in this size — 45 Shore A and 60 Shore A — provide greater deflection and better isolation at lower load levels.
A. The flat buffer family is designed for construction equipment, industrial machinery, agricultural equipment, elevators and commercial vehicles. At 70 Shore A and 1,019 kg maximum load, this specific grade is particularly suited to heavy-duty roles in construction and off-highway plant, power generation, marine, and agricultural vehicle applications where significant impact forces must be absorbed with minimal movement.
A. The rubber-to-metal bonded construction works by absorbing and dissipating impact energy when the rubber face contacts a surface or secondary moving component. This reduces transmitted shock force, protects surrounding structures and improves operator comfort. The buffer can be loaded in compression, shear, or a combination of both.
A. Yes. The 70x40 mm face size is available in 45 Shore A (7040MFB25-45) and 60 Shore A (7040MFB25-60). Additional flat buffer sizes include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41 and 10055MFB44. Custom sizes, stainless steel hardware, oil-resistant rubber and high-temperature rubber compounds are also available on request.
