Stern Tube Bearing

Name: Stern Tube Bearing
Brand: Lagersmit

Lagersmit white-metal lined stern tube bearings for oil- or grease-lubricated propeller shafts from 70 mm to approx. 900 mm, delivered pre-machined; class certificate on request.

Description

Lagersmit stern tube bearings are white-metal lined cast iron bearings that carry the radial loads of the propeller shaft and protect it against wear. In oil-lubricated systems they work on the hydrodynamic lubrication principle: at sufficient shaft speed an oil film lifts the shaft so there is no metallic contact.

Key features
