Polymer Bearing
Polymer Marine bearing is a kind of modified polymer material. It has particularly excellent friction and wear characteristics of water-oil lubrication and high physical and mechanical properties.
The polymer bearings mainly include rubber materials and plastic materials. The former is a high elastic material with good vibration absorption, which is very suitable for water lubricated bearing materials. The polymer plastic bearing is light weight, corrosion resistant and easy to make.
Polymer bearing can be used in seawater, river water and sewage, and can be used as materials for bearings, bushings, supporting sliders, gears, rollers, etc. It can applied in electrolytes such as weak acid, alkali and salt water but will not be corroded.
Overview
The polymer bearing has good lubricity and stability as well as low friction coefficient, suitable for all kinds of marine bearings on ships. It is superior to traditional bearing materials mainly in excellent physical, chemical and mechanical properties. It especially features the good chemical stability and good self-lubricity and low friction coefficient
Features:
Wear resistant and corrosion resistant
Easy water/oil lubrication performance
Low water swelling coefficient, no oil swelling
Easy installation and processing
Strong tenacity and durability
Wide application and operating temperature range
Impact load resistance
Wide operating temperature range
Higher PV values
Harmless to humans
Thanks to its good comprehensive mechanical properties, polymer bearings are widely used in: water/oil lubricated stern tube bearings, water/oil lubricated rudder bearings, oil lubricated intermediate bearings. It is also popular for adjustable pitch propeller: pitch slider, deck machinery (oil lubricated or grease lubricated).
