Product Description
Our customized marine bearings are designed for various conditions, offering excellent wear and corrosion resistance. With water-lubricated technology, they are oilless, self-lubricating, and maintenance-free, ideal for seawater and muddy environments. They feature high load capacity and long service life, ensuring reliability for propeller shafts, rudder stocks, and other marine applications. Based on customer requirements and operating conditions, we provide the best bushing material solutions, offering a highly cost-effective alternative to Thordon materials. All products are ISO certified, making them the perfect solution for shipbuilding and offshore operations.
INDRON® Material Grade
Property List of INDRON® Elastic-plastic Alloy
INDRON® elastoplastic alloy exhibits less wear than other common non-metallic bearing materials under the same conditions. It is an excellent alternative to Thordon SXL, offering longer service life, higher reliability, and lower maintenance costs. Indron® bearings are certified by the China Classification Society (CCS) and are more durable than conventional bearing materials under various conditions, including dry friction, water lubrication (clean water or water with sand and mud), non-lubrication, grease lubrication, and impact loads.
