Product Number: 2508MFB18-70
Rated at a maximum load of 231.0 kg with a controlled deflection of just 2.0 mm, the 2508MFB18-70 is a 25 x 8 mm Male Flat Buffer with an M6 x 18 mm male stud, moulded in 70 Shore A rubber, the firmest grade in this geometry and the right choice where load capacity and positional restraint take priority over movement. The rubber-to-metal bonded construction holds its form under compressive and shear loading alike, absorbing and dissipating impact energy without allowing the excessive travel that softer grades permit. At 70 Shore A, the buffer resists deformation under shock and sustained load, making it well suited to applications where secondary objects must be firmly arrested and kept in place rather than cushioned with a generous deflection range. The low-cost, easy-to-install format means fitment requires no specialist tooling, the male stud threads directly into a tapped mounting point. This grade serves the higher-load end of mainstream general-machinery mounting: construction equipment subject to repeated impact cycles, agricultural machinery operating across uneven terrain, commercial vehicles where chassis-mounted stops must absorb coachwork shock, and industrial machinery installations where surrounding structures need protection from hard contact. It is equally applicable in power generation, marine, and railway environments where firm, predictable bump-stop behaviour is a functional requirement. This buffer is available in 45 Shore A (SKU: 2508MFB18-45) and 60 Shore A (SKU: 2508MFB18-60) for applications requiring greater deflection or lighter-load isolation.

A. The 2508MFB18-70 is rated to a maximum load of 231.0 kg, making it the highest-capacity choice within the 25 x 8 mm Male Flat Buffer Shore grade range.
A. At 70 Shore A, deflection is 2.0 mm under maximum load — the least movement of the available Shore grades in this geometry, suited to applications where positional restraint is important.
A. The buffer body measures 25 mm diameter by 8 mm height. The male stud is M6 with an 18 mm thread length, for direct fitment into a tapped mounting hole.
A. Applications include construction equipment, agricultural machinery, commercial vehicles, industrial machinery, elevators, and equipment in power generation, marine, and railway environments — wherever a firm bump stop or vibration limiter is needed at moderate to higher loads.
A. Harder grades such as 70 Shore A carry higher loads with less deflection, providing firmer restraint and better performance under shock and sustained compressive load. Softer grades (45 Shore A or 60 Shore A) offer greater deflection and improved isolation at lower loads.
A. Yes — this 25 x 8 mm M6 buffer is also available in 45 Shore A (2508MFB18-45) and 60 Shore A (2508MFB18-60). Larger Male Flat Buffer sizes include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes.
