Partial data from THORDON product description
Under the same conditions, Techemer elastoplastic alloy has less wear than other common nonmetal bearing materials, and some of its models are even better than imported materials,which means Techemer bearing has longer service life, higher reliability and lower maintenance cost.
What bearing materials are more suitable as the materials used for water pump guide bearings, Babbitt alloy, rubber, ceramics or new polymer materials? It is advisable to take account of the lubrication requirements, use environment and maintenance cycle of the equipment.
Why Choose Techemer for Customized Stern Tube Bushings?
●Tailor-Made to Your Specification: We respond quickly to customized requests — offering full design flexibility on diameter, length, geometry, and tolerance. Custom molding and machining allow us to produce stern tube bushings for both new construction and retrofit projects.
●Eco-Friendly Water Lubrication: Techemer bushings operate with seawater or freshwater lubrication, eliminating oil pollution risk and helping you comply with VGP, IMO, and EAL regulations.
●High-Performance Elastomer Materials: Our bushings are made from proprietary synthetic elastomers that resist wear, corrosion, and dry-start conditions. They're tested in real-world marine environments for durability and stability.
●Versatile Installation Methods: Support for press-fit, freeze-fit, and cold bonding ensures easy integration into your existing shaft system, whether you're retrofitting or building new.
Customized Stern Tube Bushings Applications
●Bulk Carriers: custom-fit bushings with high-load tolerance
●Workboats & Fishing Vessels: optimized for sediment-heavy shallow waters
●Water Pumps: guide bearings in abrasive conditions
●Dredgers: high-abrasion environments with dry-start tolerance
●OEM Upgrades: drop-in replacements for outdated or unavailable bearing types
