Product Description
A smart lock drive often places a motor, gear train and latch mechanism inside a narrow housing. Laiwei manufactures custom spur gears for suitable electronic lock mechanisms according to customer drawings or samples. The tooth profile, bore and mounting features can be specified to fit the actual assembly.
For a new design or replacement project, the most important information is the mating gear, shaft interface and available clearance. We review the module, tooth count, face width and mounting geometry against those requirements. The lock manufacturer should validate operating cycles, sound and security performance in the complete product.

FAQs
1. Can you make a gear for an existing lock?
Yes. A drawing or sample, together with mating gear and shaft details, will help us assess it.
2. Do you supply a complete smart lock?
This page covers a gear component. Any assembly requirement needs a separate technical discussion.
3. Can you make a special hub or retention feature?
Yes, subject to drawing review and manufacturing feasibility.
4. Can you guarantee the lock’s cycle life?
The complete lock must be tested against the customer’s defined cycle-life requirement.
5. What information is needed for pricing?
A drawing or sample, quantity, material requirement and critical mating dimensions.
