Dual-Bearing Timing Belt Idler Pulley (8mm REX™ Bore, 18.5mm Diameter, 9.5mm Inside Width)

The pulley is made of polycarbonate plastic with two 8mm REX® bearings, ensuring smooth rotation and precise belt guidance.

• Weight: 7.8g
• Material: Polycarbonate pulley with high carbon steel bearings
• Bore: 8mm REX®
• Diameter: 18.5mm
• Inner width: 9.5mm

The polycarbonate pulley provides an ultra-smooth surface to run on both the smooth and toothed sides of the belt. Flanges spaced 9.5mm apart act as protective belt guides.

One bearing is flush with the plastic pulley and the other is internal. This allows for variable offset depending on the installation direction. When a pulley with an axial load is secured to the bearings, rotation remains smooth due to the alignment of the inner bearing rings.
