Built to hold firm under heavy working loads, the 5030MFB25-70 is a 70 Shore A male flat buffer measuring 50 mm diameter by 30 mm height, with an M10 x 25 male stud, rated to a maximum load of 504.0 kg and a deflection of just 7.5 mm, the firmest grade in this geometry, designed for applications where minimal movement and maximum load-bearing are the priority. Rubber-to-metal bonded construction gives this buffer its characteristic combination of structural integrity and energy absorption. At 70 Shore A, the rubber compound delivers high resistance to compression, making it suited to shock and impact duties where a softer grade would deflect too readily. The flat buffer geometry provides low-cost shock and vibration absorption whilst acting as an elastic element in direct contact with a surface or as a bumper against secondary moving components. Installation is straightforward by virtue of the threaded male stud, and the bonded construction ensures the rubber element remains positively located under repeated loading cycles. The firm hardness grade makes this buffer the appropriate choice where heavier loads, sudden impact forces, or a requirement to restrain movement are the governing design criteria. Typical applications include construction equipment, commercial vehicles, agricultural machinery, and industrial plant, sectors where buffers must resist sustained compression from external moving components without excessive travel. The buffer also serves power generation, marine, and railway and mass transit installations where shock loads demand a high-resistance elastic element.

A. This buffer is rated to a maximum load of 504.0 kg and has a deflection of 7.5 mm, reflecting the high resistance to movement characteristic of the 70 Shore A hardness grade.
A. The body measures 50 mm diameter by 30 mm height (D x H). The male stud is M10 x 25 mm (thread diameter x thread length).
A. At 70 Shore A, this is the firmest grade in the 50 x 30 mm flat buffer range. Harder grades carry higher loads with less movement, making them the correct choice for heavy-load, shock, or impact-restraint applications where a softer grade would deflect excessively. Softer 45 Shore A (5030MFB25-45) and 60 Shore A (5030MFB25-60) alternatives are available where greater deflection or better isolation at lower loads is required.
A. Male flat buffers in this hardness grade are used across construction and off-highway equipment, agricultural machinery, commercial vehicles, industrial plant, power generation, marine installations, and railway and mass transit applications — wherever external moving components impose impact or shock loads that must be absorbed and dissipated.
A. The buffer absorbs and dissipates energy when a secondary object contacts its rubber face, cushioning the impact and reducing transmitted force. The M10 x 25 male stud threads directly into a tapped hole or a nut in the mounting structure, making installation straightforward without additional hardware.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes beyond the standard range.
