Wärtsilä Intermediate Shaft Bearings

All products offer the advantages of being fully split hence replaceable and serviceable

Wärtsilä’s intermediate shaft bearing solutions are fully split, self-aligning, oil lubricated radial support bearings made from cast iron with centrifugally cast white metal bearing surfaces.

The spherical self-aligning design promotes easy alignment, and reduces wear. The designs are also prepared for cooling and can be fitted with a complete monitoring of temperatures and oil levels on request.
