Q 1. What are the key dimensions of the PB238 plate buffer?

A. The PB238 has an overall length (A) of 105.0 mm, a flange diameter (D1) of 121.0 mm, a base diameter (D2) of 86 mm, a core diameter (D3) of 57.0 mm, a height (H) of 56 mm, a stud diameter (d) of 8.6 mm, and a stud length (S) of 6.3 mm.

Q 2. What is the maximum load rating for the PB238?

A. The PB238 plate buffer has a maximum load rating of 4,200 kg, making it the highest-capacity buffer in the standard range and suited to heavy general-machinery mounting applications.

Q 3. What industries and applications is the PB238 plate buffer suited to?

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

Q 4. How does a male flat plate buffer work?

A. Male flat plate buffers absorb and dissipate impact energy between a moving component and a fixed surface. The rubber-to-metal bonded construction allows the mount to accept forces in compression, shear, or a combination of both, reducing shock transfer to surrounding structures and improving machinery lifespan.

Q 5. Are custom material options available for the PB238?

A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes.

Q 6. Which other sizes are available in the PB238 plate buffer range?

A. The range includes PB15, PB260, and PB335, each offering different dimensional envelopes and load capacities. The PB238 is the largest in the standard range at 105.0 mm overall length and 4,200 kg maximum load.
