Specifications

Application

Durus rotary shaft oil seals are used in pumps, gear reducers, motors, agitators, conveyors, automotive transmissions, and rotating equipment where lubricant must be retained and contaminants excluded. Operating temperature range: -40°F to 250°F. Compatible with mineral oils, lubricating greases, hydraulic fluids, and most industrial fluids.

Installation: Press into the housing bore using a flat-faced installation tool. The seal face should be flush or slightly recessed from the housing face. Lubricate the lip lightly before installation. Use a Durusleeve to restore shafts with wear grooves from prior seal contact.
