They are an excellent alternative to Thordon XL, 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. Why Choose INDRON? Bearing Bushing? Eco-Friendly LubricationWater serves as the primary lubricant, eliminating the risk of water contamination caused by lubricant grease leakage.Durable and Maintenance-FreeMade 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 ResistanceOptimized for balanced friction and outstanding abrasion resistance, the bearings effectively disperse wear particles to protect the shaft surface from damage.Customized SolutionsTailored material formulations and bearing designs are available based on specific operational conditions and equipment requirements.Certified QualityISO 9001:2015 certified, Techemer remains committed to customer-centric innovation and uncompromising quality standards.
