Q 1. What are the key dimensions and load rating of the PB130 square plate buffer?

A. The PB130 has an outer plate dimension (D1) of 130 mm, a top face dimension (A and D2) of 100 mm, a height (H) of 78 mm, a bore diameter (d) of 11 mm, and a stud/bolt spacing (S) of 6 mm. The maximum load rating is 9,500 kg.

Q 2. What applications is the PB130 square plate buffer suitable for?

A. The square plate buffer family is used across elevators, agricultural equipment, construction and off-highway machinery, industrial machinery, and commercial vehicles. Industries served include marine, railway and mass transit, power generation, automotive, and military and defence.

Q 3. How does the PB130 square plate buffer work?

A. The buffer works by absorbing and dissipating energy on contact, cushioning machinery against impact shocks from external moving components. It can act as an elastic element in direct contact with a surface and may be loaded in shear, compression, or a combination of both.

Q 4. What construction method is used in the PB130?

A. The PB130 uses rubber-to-metal bonded construction, which bonds the rubber element to the metal plate to maintain integrity under repeated loading and ensure consistent energy absorption performance.

Q 5. How does rubber hardness affect performance in square plate buffers?

A. Softer grades give greater deflection and better isolation at lower loads, making them well suited to lighter or sensitive installations. Harder grades carry higher loads with less movement. The PB130 sits at the lighter, compact end of the square plate buffer range.

Q 6. Are custom sizes or specialist materials available for the PB130 square plate buffer?

A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubbers, as well as additional and custom sizes, are available on request.

Q 7. Which other sizes are available in the square plate buffer range?

A. The range also includes PB50, PB63, PB100, PB125, PB160, PB1700-2, PB200, and PB250, covering a broad spread of plate dimensions and load capacities.
