Our customized marine bearings are engineered for diverse and demanding operating conditions, providing outstanding wear and corrosion resistance. Using advanced water-lubricated technology, these bearings are oilless, self-lubricating, and maintenance-free-perfectly suited for seawater and muddy water environments.
With high load capacity and extended service life, they ensure long-term reliability for propeller shafts, rudder stocks, stern tubes, and other critical marine components.
Designed as a highly cost-effective and performance-matching alternative to THORDON SXL, our bushings deliver equivalent durability, lubrication efficiency, and environmental adaptability-at significantly lower cost.
Based on specific customer requirements and working conditions, we offer optimized bushing material solutions. All products are ISO certified, making them a trusted choice for shipbuilding, marine retrofits, and offshore engineering applications.

Why Choose INDRON® Bearing Bushing?
-
Eco-Friendly Lubrication
Water serves as the primary lubricant, eliminating the risk of water contamination caused by lubricant grease leakage.
-
Durable and Maintenance-Free
Made from elastic-plastic alloys bonded with lubricative particles, INDRON® bearings can withstand impulsive and edge loads. They support dry start-up and are designed for maintenance-free operation.
-
Exceptional Wear Resistance
Optimized for balanced friction and outstanding abrasion resistance, the bearings effectively disperse wear particles to protect the shaft surface from damage.
-
Customized Solutions
Tailored material formulations and bearing designs are available based on specific operational conditions and equipment requirements.
-
Certified Quality
ISO 9001:2015 certified, Techemer remains committed to customer-centric innovation and uncompromising quality standards.
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.
