Subheadings
Products classified under HTS 8482.91.00
Ceramic Silicon Nitride Bearing Balls
High-performance silicon nitride ceramic balls for hybrid bearings in high-speed automotive and aerospace applications. Their non-magnetic and corrosion-resistant properties justify classification under HTS 8482.91.00 as bearing rollers.
Precision Tungsten Carbide Bearing Balls
Ultra-hard tungsten carbide balls for extreme wear applications in pump seals and precision instruments. Classified as bearing balls under HTS 8482.91.00 despite specialized applications.
Cylindrical Roller Bearing Elements
Straight cylindrical steel rollers for radial roller bearings in electric motors and conveyor systems. Their barrel-free profile classifies them under HTS 8482.91.00 as bearing rollers.
Miniature Bearing Balls
Micro-precision steel balls (1-5mm diameter) for miniature bearings in computer HDDs, medical devices, and precision instruments. HTS 8482.91.00 covers all bearing ball sizes.
Spherical Bearing Rollers
Barrel-shaped rollers with spherical outer surfaces for self-aligning roller bearings in mining equipment. The convex profile compensates for shaft misalignment under HTS 8482.91.00.
High-Carbon Chrome Roller Pins
Hardened high-carbon chrome steel rollers functioning as needles in planetary gear bearings. Classified under HTS 8482.91.00 for bearing applications.
Glass Bearing Balls
Precision soda-lime glass balls for low-load instrumentation bearings and fiber optic connectors. Non-magnetic properties ideal for sensitive applications under HTS 8482.91.00.
Polymer Bearing Rollers
PTFE or nylon cylindrical rollers for low-speed, corrosion-resistant bearing applications in food processing. Classified under HTS 8482.91.00 when designed as bearing elements.
Large Diameter Bearing Rollers
Heavy steel rollers (100-300mm diameter) for wind turbine and paper mill bearings. Extreme size for high-capacity applications under HTS 8482.91.00.
Automotive Wheel Bearing Balls
High-volume chrome steel balls specifically for automotive hub and wheel bearings. Engineered for combined radial/axial loads under HTS 8482.91.00.
Turbocharger Bearing Rollers
High-temperature alloy steel rollers for turbocharger journal and thrust bearings. Extreme RPM and heat specifications under HTS 8482.91.00.
Precision Instrument Needle Rollers
Ultra-precision needle rollers (0.5-2mm diameter) for gyroscopes, avionics, and scientific instruments. Sub-micron tolerances under HTS 8482.91.00.
Tapered Bearing Rollers
Conical steel rollers for tapered roller bearings used in heavy truck axles and industrial gearboxes. The tapered profile enables handling combined radial and axial loads under HTS 8482.91.00.
Chrome Steel Bearing Balls
Precision-ground chrome steel balls used as rolling elements in ball bearings for industrial machinery. These balls feature high hardness and wear resistance, classified under HTS 8482.91.00 as parts of ball or roller bearings.
Stainless Steel Needle Rollers
Cylindrical stainless steel needle rollers for needle roller bearings in automotive transmissions and textile machinery. Their small diameter-to-length ratio defines them as needles under HTS 8482.91.00.
