Duff-Norton 2000 Series
Shock & Vibration Resistant

Rotary Unions ®

Duff-Norton’s Series 2000 is designed with two
ball bearings spaced to withstand radial and
thrust loads. The compression springs in the
Series 2000 provide even loading across the
seal surfaces to maintain zero leakage even in
low pressure applications. Series 2000 is
designed with an integral flange which allows
Rotary Union ® repairs without removing the
housing from the machine. The flange attaches
directly to the machine journal, providing
inherently concentric mounting, minimizing
overhang, and partially relieving bearing load to
increase service life.
