Description:

Size - Aperture Diameter: 5mm; Outer Diameter: 40mm; Overall Thickness: 17.5mm; Groove Width: 7mm; Groove Depth: 4.8mm; Step Thickness: 7.5mm; Step Diameter: 25mm; Applicable Belts: 6mm PU round belt.. Material - The single-groove pulley is made of aluminum alloy, with small precision error, stable operation, high-speed rotation without shaking, effectively suppressing transmission noise and fluctuations, and improving the stability of the belt operation.. Usage - First, you need to measure the diameter of the shaft to be installed. For example, if the diameter of the shaft is 8 mm, the inner diameter of the pulley should be 8 mm, so that the installation will be just right.. Application - Silver aluminum alloy single slot is suitable for motors, micro spindles, model transmission design, motor shaft transmission, etc..
