Product Number: 4030MFB25-70
Variations
Carrying a maximum load of 242.5 kg with a controlled deflection of just 7.5 mm, the 4030MFB25-70 is a 70 Shore A male flat buffer engineered for general machinery applications where higher loads and minimal movement are the priority. At 40 mm diameter by 30 mm height with an M10 x 25 stud, it occupies the firm end of this flat buffer family and is built to hold its position under sustained compression or combined shear and compression loading. Constructed from rubber bonded directly to metal, this buffer absorbs and dissipates impact energy rather than allowing it to transmit through the machine structure. The 70 Shore A hardness rating means the rubber resists deformation under load, making it well suited to shock and impact scenarios where softer grades would yield too far. It reduces impact force from secondary moving components, acts as an elastic element in direct contact with a surface, and contributes to improved machinery lifespan, protection of surrounding structures and enhanced operator comfort. Typical installation environments include construction equipment, agricultural machinery, commercial vehicles and industrial plant where bump stop duties involve heavier intermittent loading or where positional control of a component is as important as vibration damping. The rubber-to-metal bonded construction allows fast fitting and reliable retention under working conditions. Stainless steel hardware and oil-resistant or high-temperature rubber compounds are available on request for more demanding service environments.

A. The 4030MFB25-70 has a maximum load capacity of 242.5 kg, with a deflection of 7.5 mm at that load. The 70 Shore A hardness grade provides firm resistance, minimising movement under heavy or shock loading.
A. The buffer body measures 40 mm diameter by 30 mm height (D x H: 40 x 30). The male stud is M10 with a 25 mm thread length (d x L: M10 x 25).
A. A 70 Shore A rating places this buffer at the firm end of the range. Harder grades carry higher loads with less movement — making the 4030MFB25-70 the correct choice when positional control, shock resistance, or heavier intermittent loading matters more than maximum vibration isolation. Softer grades (45 or 60 Shore A) offer greater deflection and better isolation at lower loads.
A. The flat buffer family is suited to construction equipment, industrial machinery, agricultural equipment, commercial vehicles and elevators. At 70 Shore A, this particular variant is best placed where the mount must withstand higher load or impact from secondary moving components — for example as a bump stop or rigid surface contact element in heavy plant or agricultural machinery.
A. The rubber-to-metal bonded construction absorbs and dissipates impact energy before it can transmit into the machine structure. It can be loaded in compression, shear, or a combination of both, reducing peak impact force, protecting surrounding structures and improving operator comfort.
A. Yes. The 40 x 30 mm male flat buffer is also available in 45 Shore A (4030MFB25-45) and 60 Shore A (4030MFB25-60). Alternative sizes across the male flat buffer range include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41 and 10055MFB44.
A. Yes — stainless steel metal components and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes. Contact the team with your specific requirements.
