Composite Bearing – 3.1/2″ x 4.1/2″ x 14″

Our water-lubricated composite-shelled marine shaft bearings are engineered to provide exceptional performance, durability, and corrosion resistance in demanding marine environments. Manufactured using high-quality composite shell materials combined with durable nitrile rubber, these bearings offer a lightweight and maintenance-friendly alternative to traditional brass-shelled bearings.

Composite-shelled bearings are particularly well suited to applications where corrosion resistance is essential, as the non-metallic shell construction eliminates the risk of dezincification and electrolytic corrosion commonly associated with metal components. Their lightweight design also makes handling and installation easier while reducing overall system weight.

In addition, composite shells offer excellent vibration and noise dampening properties, helping to improve operational smoothness and reduce transmitted vibration through the shaft system. The material is also highly resistant to marine growth, water absorption, and chemical exposure, making it ideal for long-term use in harsh saltwater conditions.
