Product Number: PB250
At the heavy-duty end of the square plate buffer range, PB250 is engineered to absorb and dissipate high-impact energy loads in demanding industrial and off-highway applications. With a maximum rated capacity of 38,220 kg, a plate face dimension of 200 × 200 mm (D2) and an overall base diameter of 250 mm, this is the largest buffer in the family and is specified where shock forces and sustained compression loads would overwhelm smaller units. Constructed using rubber-to-metal bonded technology, PB250 works by absorbing and dissipating energy on contact, cushioning machinery against impact shocks from external moving components. The rubber element operates under compression or a combination of shear and compression, with the 200 mm mounting plate (A) and 13 mm bore (d) providing a secure, stable interface with the host structure. An overall height of 160 mm (H) and plate thickness of 8 mm (S) give the buffer the structural depth required to handle high-load and shock-duty cycles without premature fatigue. Typical high-load and heavy-duty applications include construction and off-highway equipment, commercial vehicles, agricultural machinery, industrial plant, power generation equipment, and marine installations. The buffer improves machinery lifespan, protects surrounding structures from repeated impact, and contributes to operator comfort under arduous working conditions. Stainless steel hardware and oil-resistant or high-temperature rubber compounds are available on request, along with custom sizes. PB250 is the largest unit in the square plate buffer range. Smaller sizes are available: PB200, PB160, PB130, PB125, PB100, PB63, and PB50.
The Square Plate buffers are an effective alternative solution to absorbing high levels of shock and load, giving equipment excellent protection. The heavy-duty rubber and mild steel flange, with four pre-drilled bolt holes, allows this mount to be extremely versatile.

A. The PB250 has a maximum rated capacity of 38,220 kg, making it the highest-load unit in the square plate buffer range and suited to heavy-duty and high-shock duty applications.
A. The PB250 has a base diameter (D1) of 250 mm, a square plate face dimension (D2) of 200 × 200 mm, a mounting plate size (A) of 200 mm, a bore diameter (d) of 13 mm, an overall height (H) of 160 mm, and a plate thickness (S) of 8 mm.
A. The PB250 is suited to high-load and shock-duty applications including construction and off-highway equipment, commercial vehicles, agricultural machinery, industrial plant, power generation equipment, and marine installations. It cushions machinery against impact shocks from external moving components and acts as an elastic element in direct contact with a surface.
A. It uses rubber-to-metal bonded construction to absorb and dissipate impact energy. The rubber element operates under compression or a combination of shear and compression, reducing impact force transmitted to the host structure and protecting surrounding components.
A. Yes. Stainless steel metal components and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes.
A. The range includes PB50, PB63, PB100, PB125, PB130, PB160, PB200, and PB250. The PB250 is the largest unit; select the variant that matches your load capacity and dimensional requirements.
