✅ Specifications
- Series: XL, trapezoidal tooth, pitch 5.08mm
- Tooth Count: 15T /16T /18T /20T
- Profile: AF type (both sides flat, no step)
- Belt Groove Width: 11mm, suitable for 10mm width XL timing belt
- Total Thickness: 15mm
- Material: Pulley body: Aluminum alloy; retaining flange: iron zinc plated
- Fastener: 2 pcs M4/M5 set screws included
✅ Features
1. AF both-sides flat design, no shoulder, compact installation.
2. Keyway hole processed by broaching machine, width tolerance ±0.05mm, depth tolerance ±0.2mm.
3. Comes with 2pcs 90° set screws for locking shaft firmly.
4. Lightweight aluminum main body, galvanized iron flange to prevent belt falling off.
5. High tooth precision, stable transmission, low noise.
✅ Application
Widely used for CNC machine, stepper motor, printer, automation equipment, small power transmission system, packaging machinery etc.
⚠️ Notes
1. Default option is plain bore without keyway unless keyway size is selected.
2. For large bore sizes: set screw may protrude to tooth surface due to wall thickness. Solutions: make countersink hole on shaft, use anaerobic adhesive, or grind the set screw shorter.
3. For keyway bore versions: screw hole will be placed at 180° opposite side of keyway to guarantee enough thread length, this is normal and not product defect.
4. The pulley surface has no finishing treatment, slight oxidation may occur.
5. Overall dimensions may change slightly by production batch without prior notice.
6. Only set screws are included, pin keys need separate purchase.
