Products classified under HTS 8483.50.90.40
V-Belt Grooved Pulley for Industrial Motors
This grooved pulley is designed with a V-shaped groove to securely engage V-belts in industrial motor drive systems, transmitting power from the motor to connected machinery. It falls under HTS 8483.50.90.40 as a grooved pulley within the category of flywheels and pulleys. Made typically from cast iron or steel for durability in high-torque applications.
Timing Belt Grooved Pulley for Automotive Engines
A precision grooved pulley with teeth for timing belts in car engines, synchronizing crankshaft and camshaft rotation to ensure valve timing accuracy. Classified under HTS 8483.50.90.40 due to its grooved design for power transmission via belts. Typically aluminum for weight reduction in vehicles.
Cast Iron Grooved Drive Pulley for Conveyor Systems
Heavy-duty cast iron pulley with multiple V-grooves for driving belts in material handling conveyor systems, providing reliable power transfer in warehouses. It qualifies for HTS 8483.50.90.40 as an 'other' grooved pulley used in industrial transmission. Corrosion-resistant coating enhances longevity.
HVAC Fan Motor Grooved Pulley
Adjustable grooved pulley for V-belts connecting HVAC fan motors to blower wheels in air handling units, enabling speed variation for airflow control. Falls under HTS 8483.50.90.40 as a transmission grooved pulley. Steel construction with machined grooves for precise belt tensioning.
Multi-Groove Poly-V Belt Pulley for Compressors
Poly-V belt pulley with 8 longitudinal grooves for serpentine drive in industrial air compressors, handling high-speed rotation without slippage. Classified in HTS 8483.50.90.40 for its specialized grooved transmission design. Balanced aluminum construction reduces vibration.
Steel Grooved Idler Pulley for Belt Tensioners
Deep-groove steel idler pulley used in automatic belt tensioners to maintain proper belt wrap and tension in machinery drives. HTS 8483.50.90.40 applies to this grooved pulley despite idler function in transmission systems. Sealed bearings ensure maintenance-free operation.
Machined Aluminum Grooved Pulley for Lathes
Precision CNC-machined aluminum pulley with custom grooves for belt drives on metalworking lathes, providing variable spindle speeds. Under HTS 8483.50.90.40 as specialized grooved transmission pulley. Lightweight design minimizes lathe vibration.
