1. The timing belt pulley of this link is divided into two types: through-hole and keyway hole according to the inner hole.
2. The default size of the keyway is through-hole, so please pay attention to the distinction when purchasing.
3. The keyway hole adopts the broaching process, the key degree error 0.05mm, the key depth error 0.1mm range, the specific size of the physical shall prevail.
4. The synchronous wheel you choose is only delivered with fixed machine screws, with the keyway with that pin key need to be purchased separately with the use.
5. The synchronous wheel material is aluminium alloy, the retaining edge iron galvanized, no surface treatment, there may be a little oxidation phenomenon.
6. The dimensions (step, total thickness, screw holes, baffle diameter, etc.) may change according to the batch, so we will not inform you separately.
7. The default bore is through-hole + top wire. The keyway size appears after the bore before the keyway hole + screw hole option.
