Engineered to withstand heavy loading and impact shock, the 50 x 21 mm Male Flat Buffer in 70 Shore A rubber (SKU 5021MFB25-70) delivers a maximum load capacity of 708.0 kg with a controlled deflection of just 5.3 mm, making it the high-load, minimum-movement choice within the 50 x 21 mm flat buffer range. The M10 x 25 male stud ensures direct, secure installation wherever a firm, shock-resisting mount is required. At 70 Shore A, the rubber compound is formulated for applications where components must be held firmly against movement whilst still absorbing impact energy. The rubber-to-metal bonded construction distributes load across the full contact face, resisting both compressive forces and shear loads without delamination. This grade is the correct selection when load amplitude is high, positional movement must be minimised, or when the mount acts as a positive stop against secondary impact shock. Typical duties include bump-stop and end-of-travel damping on construction and off-highway plant, shock absorption on agricultural machinery where repeated heavy strikes occur, and vibration restraint on commercial vehicles, marine installations, and railway or mass-transit equipment. The male flat buffer format places the rubber directly between surfaces, working in compression or a combination of compression and shear to absorb and dissipate energy, reduce transmitted impact force, and protect surrounding structures. Stainless steel hardware and oil-resistant or high-temperature rubber compounds are available on request for specialised service environments.

A. This 70 Shore A Male Flat Buffer has a maximum load capacity of 708.0 kg and a deflection of 5.3 mm, making it suited to heavy-load applications where minimal movement is required.
A. The buffer body measures 50 mm diameter by 21 mm height (D x H: 50 x 21). The male stud is M10 with a length of 25 mm (d x L: M10 x 25).
A. At 70 Shore A this is the firmest grade in the 50 x 21 mm Male Flat Buffer range. Choose it when loads are high, positional movement must be minimised, or the mount needs to resist repeated impact shock. Softer grades (45 Shore A and 60 Shore A) offer greater deflection and improved isolation at lower loads.
A. Male Flat Buffers in this family are used across construction and off-highway equipment, agricultural machinery, commercial vehicles, marine installations, railway and mass-transit equipment, and industrial machinery wherever shock absorption, bump-stopping, or vibration restraint is needed.
A. The rubber-to-metal bonded construction absorbs and dissipates energy when the rubber face is loaded in compression, shear, or a combination of both. This cushions impact shock, reduces the force transmitted to surrounding structures, and helps protect machinery and improve operator comfort.
A. Yes — stainless steel metal components and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
A. Additional sizes in the Male Flat Buffer range include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44, alongside other configurations within the 50 x 21 mm family.
