Product Number: PB50
Compact and suited to lighter-duty installations, the PB50 square plate buffer measures 50 mm outer diameter with a 40 mm square plate and a working height of 32 mm, making it the smallest footprint in the square plate buffer range. Its rubber-to-metal bonded construction absorbs and dissipates energy on contact, cushioning machinery against impact shocks from external moving components and reducing impact force transmitted to surrounding structures. With a maximum load rating of 1,530 kg, the PB50 is well positioned for sensitive or compact installations where space is at a premium and vibration control demands a reliable elastic element in direct contact with a surface. The male flat buffer design keeps installation straightforward. The 5.5 mm mounting hole diameter (d) and 2 mm steel plate thickness facilitate secure fixing to machinery frames and base structures. Rubber-to-metal bonding ensures consistent performance under repeated loading in compression, shear, or a combination of both, while the rubber element absorbs shock energy to protect equipment and improve operator comfort over sustained use. Applications include agricultural equipment, elevators, and industrial machinery where compact buffer footprints are required. The buffer is equally suited to construction equipment and commercial vehicles where controlling low-to-moderate impact loads from secondary moving components is a priority. Full specification: outer diameter D1 50 mm, square plate side A 40 mm, base diameter D2 40 mm, mounting hole d 5.5 mm, height H 32 mm, plate thickness S 2 mm, maximum load 1,530 kg.
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 PB50 has an outer diameter (D1) of 50 mm, a square plate side (A) of 40 mm, a base diameter (D2) of 40 mm, a mounting hole diameter (d) of 5.5 mm, a height (H) of 32 mm, a plate thickness (S) of 2 mm, and a maximum load rating of 1,530 kg.
A. The PB50 uses rubber-to-metal bonded construction. It works by absorbing and dissipating energy on contact, cushioning machinery against impact shocks from external moving components and reducing the force transmitted to surrounding structures. It can be loaded in shear, compression, or a combination of both.
A. The PB50 is suited to agricultural equipment, elevators, industrial machinery, construction equipment, and commercial vehicles. It is particularly well matched to compact or sensitive installations where a smaller buffer footprint is needed for reliable vibration and shock control.
A. The PB50 is the smallest model in the square plate buffer range. For higher load capacities or larger plate sizes, alternative models include the PB63, PB100, PB125, PB130, PB160, PB1700-2, PB200, and PB250.
A. Yes. Stainless steel hardware and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes.
