Rudder Bushing Sizes

Molded Rubber

DX Rudder Bushings are molded from a 70 Scale D, Durometer, Nitrile Rubber Compound, formulated to withstand the rugged “impact” service encountered in ship’s rudder steering systems. They possess high rigidity for maximum dimensional stability while still retaining a degree of resiliency required to dampen peak shock loads.

DX Rudder Bushings are homogenous cylinders molded with longitudinal lubrication grooves. Grease, oil and water serve equally well as lubricants. The DX Rudder Bushing is resistant to deterioration by hydrocarbons, acids, salt water corrosion and electrolysis.

CAUTION: DX Rudder Bushings are supplied with molded I.D. and O.D. boring I.D. dimensions do not remove more than 70% of the lubricant groove depth.

IMPORTANT: DX Rudder Bushings must be mechanically secured with set screws or other locking devices to prevent movement during operation and the expected operating temperature range.
