Subheadings
Products classified under HTS 8483.30.80
Bronze Bushing for Industrial Machinery
A cylindrical bronze plain shaft bearing designed to reduce friction between rotating shafts and housings in heavy industrial equipment like conveyors and pumps. It falls under HTS 8483.30.80 as a plain shaft bearing, not incorporating balls or rollers, used in mechanical power transmission systems. These bushings provide self-lubricating properties for high-load applications.
Sintered Iron Plain Bearing
A powdered metal sintered iron bearing used in automotive and appliance motors for smooth shaft rotation without ball or roller elements. Classified under HTS 8483.30.80 as 'other' plain shaft bearings for mechanical applications. Its porous structure allows oil impregnation for lubrication.
PTFE-Lined Shaft Bearing
A self-lubricating plain shaft bearing with polytetrafluoroethylene (PTFE) lining on a metal backing for low-friction performance in food processing equipment. HTS 8483.30.80 covers this as an 'other' plain bearing without rolling elements. Ideal for hygienic, maintenance-free applications.
Graphite Impregnated Bronze Bushing
Solid lubricant graphite plugs embedded in bronze bushing for high-temperature, high-load shaft support in steel mill equipment. Falls under HTS 8483.30.80 as plain shaft bearing 'other' for severe industrial conditions. Eliminates need for external lubrication.
Composite Polymer Plain Bearing
Engineered polymer composite plain bearing combining nylon, fiberglass, and lubricants for automotive suspension pivots. Classified HTS 8483.30.80 as 'other' plain shaft bearings serving mechanical transmission functions. Offers corrosion resistance and noise reduction.
Oilite Sintered Bronze Bearing
Trademarked Oilite brand oil-impregnated sintered bronze plain bearing for fractional horsepower electric motors. HTS 8483.30.80 'other' plain shaft bearings perfectly describes this porous, self-lubricating component. Widely used in HVAC fans and power tools.
