FAQ

What is the correct bolt tightening torque for the DBZ 226 HHS disc pack?

The correct torque is critical for performance and safety. Always refer to the official Rexnord Thomas installation manual for the DBZ 226 series. Using incorrect torque can lead to premature failure.

Is this disc pack compatible with other coupling series besides DBZ?

No, this DPK DBZ 226 HHS disc pack is specifically designed for the Rexnord Thomas DBZ Series, size 226 coupling. It is not interchangeable with other series like the AMR or BMR, as dimensions and bolt patterns will differ.

Can I replace just a single damaged disc from the pack?

No, the disc pack is a factory-assembled and balanced unit. You must replace the entire pack if any disc shows signs of wear, fatigue, or damage. Attempting to replace individual discs will compromise the coupling’s balance and integrity.
