3418 Series 5mm HTD Pitch Timing Belt Idler Pulley (6mm Bore, 8 Tooth) - 2 Pack

These 3418 series pulleys are designed for systems where the tensioner pulley must contact the toothed side of the belt. The 8-tooth profile with a 5 mm pitch (HTD) ensures that the belt runs over the pulley without the vibration and jumps that occur when teeth contact a smooth surface. The 6 mm diameter mounting hole provides free rotation (slip-fit) on standard shafts, bolts or racks of the corresponding diameter.

• Weight: 0.8 g (each)
• Tooth profile: HTD 5 mm
• Number of teeth: 8
• Inner diameter (Bore): 6 mm
• Material: Wear-resistant plastic
• Quantity per package: 2 pcs.

The pulleys are made of lightweight polymer, which minimizes system inertia and reduces noise during operation. They are ideal for compact drives in robotics, where precise maintenance of the belt path under load is required.

For correct operation, it is recommended to install the pulley so that the belt has a sufficient wrap angle for reliable engagement. Since the part does not have built-in bearings, at high rotation speeds it is advisable to use a small amount of dry lubricant on the surface of the 6 mm shaft to reduce friction.
