Product Number: PB63

Compact by design, the PB63 Square Plate Buffer is a rubber-to-metal bonded bump stop measuring 63 mm across the base plate with a 50 mm rubber face, 40 mm overall height, and a 6.5 mm fixing hole, engineered to cushion sensitive installations and lower-load applications against impact shocks from external moving components. At the smaller end of the square plate buffer range, it is particularly well suited to situations where space is limited or where lighter machinery and structures require reliable, low-profile protection without over-engineering the mount. The PB63 operates by absorbing and dissipating energy on contact, reducing impact force transmitted to the host structure or the secondary object striking it. Rubber-to-metal bonded construction ensures secure integration and consistent performance under repeated loading. With a maximum load rating of 2,440 kg and a 3 mm steel plate thickness, the buffer delivers meaningful capacity within a compact footprint. The rubber element may be loaded in compression, shear, or a combination of both, giving engineers flexibility in installation orientation. Typical applications for this size of square plate buffer span construction equipment, agricultural machinery, commercial vehicles, elevators, and general industrial machinery where controlled cushioning of lighter impacts is required. Industries including marine, power generation, and automotive manufacturing also employ buffers of this type to protect surrounding structures, extend machinery service life, and improve operator comfort. Custom options including oil-resistant or high-temperature rubber compounds and stainless steel metalwork are available on request.
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 PB63 has a base plate dimension (D1) of 63 mm, a rubber face dimension (D2) of 50 mm, a side dimension (A) of 50 mm, an overall height (H) of 40 mm, a fixing hole diameter (d) of 6.5 mm, and a steel plate thickness (S) of 3 mm.
A. The PB63 Square Plate Buffer has a maximum load rating of 2,440 kg, making it suitable for lighter and medium-duty cushioning duties within the square plate buffer range.
A. The PB63 is used across construction equipment, agricultural machinery, commercial vehicles, elevators, and general industrial machinery. It is also found in marine, power generation, and automotive applications where compact, lower-load impact cushioning is required.
A. The buffer works by absorbing and dissipating energy when an external moving component makes contact with it. The rubber-to-metal bonded element may be loaded in compression, shear, or a combination of both, reducing the impact force transmitted to the host structure or machinery.
A. Yes — the PB63 sits at the smaller end of the range and is particularly suited to sensitive installations, lighter loads, and applications where a compact footprint is needed. Larger sizes including PB80, PB100, PB125, PB130, PB160, PB1700-2, PB200, and PB250 are available.
A. Yes — oil-resistant rubber, high-temperature rubber compounds, and stainless steel metalwork options are available on request, in addition to custom sizes.
