American Standard 3V 2-Groove Compact V-Belt Pulley, for Small Fans and Precision Packaging Machinery

The 23V265TB is an American-standard 3V 2-groove taper-bush pulley built for high-speed, light-load, space-constrained applications. Its extremely low moment of inertia and compact axial structure make it an ideal choice for direct-coupled small motors and precision transmission.

1. Very low moment of inertia, suited to high speeds: The 3V narrow-section design combined with a compact 2.65-inch outside diameter greatly reduces energy loss at start-up. At high motor speeds it produces little centrifugal force and responds very quickly, making it an excellent partner for small machines with high speed requirements.
2. Low overhung load, protecting motor bearings: Compared with bulky, heavy cast iron pulleys, the 23V265TB significantly reduces the weight on the drive shaft end. This eases uneven wear on motors and bearings and extends the overall life of small powertrains.
3. Noise reduction at high frequency, smooth running: Precision-machined from HT250 gray cast iron, which naturally has excellent vibration-damping properties. At high rpm it effectively suppresses resonance and keeps mechanical noise to a minimum.
4. Minimal maintenance, suited to small shaft systems: Paired with lightweight TB1008/TB1108 taper bushes, it needs no hammering on the motor shaft. Stocking a few pulley bodies is enough to fit many micro-motor shaft diameters from 10mm to 25mm by swapping bushes, simplifying spare-parts storage for overseas customers.

A dedicated drive pulley for small equipment: Compact, lightweight, and responsive, it handles compact equipment that conventional heavy pulleys cannot.
Classic North American standard replacement part: A precise, dimension-for-dimension substitute for small fan and water pump parts in the North American market.

Precision light industry: Automatic packaging machines, small woodworking engraving machines, and label printing equipment.
HVAC equipment: Small air coolers, exhaust fans, and air purification systems.
Micro power equipment: Household car washers, small air compressors, and auxiliary drives on automotive inspection lines.
