Special note
:
※  4 / 5 mode spur gear, the surface was not quenched by high frequency.
※ The gear is a gear molding process. A slightly eccentric phenomenon occurs. If you have requirements for the accuracy of the gear, please take a careful shot or contact customer service.
※ Involute gears can be inserted correctly even if there are deviations in the center distance, and it is easier to obtain the correct tooth shape.
※ The gear material is 45 # steel, which can have rust in the water, which is normal and does not affect normal use.
※ The inner hole is the process hole punched by the drill (burr hole). The deviation is large and depends on the batch. Contact customer service for more information.
※ The outer dimensions (such as inner hole size, total thickness and other data) can change depending on the batch. The data is for reference only and the actual product takes precedence.
Tips: The pictures are for reference only and the size, color, printing, etc. are subject to the actual product.

Regarding dimensional error:
When manufacturing parts, in order to make the parts interchangeable, they should be within the specified maximum size and minimum limit size. The allowable size variation is called: tolerance, screws generally have positive and negative tolerances, specific tolerances The value varies according to the classification of the screw, but they are all within the range specified by the industry. Please consult the online customer service for specific tolerances. If the product is ordered, it is deemed to accept this tolerance by default.
Shopping Notes:
1. At the top of the eBay listing, from top to bottom, first select the design, and then select option 1 and option 2 or option 3 of the product....More options.
2. Then, if you select the corresponding number under "Quantity", you can purchase the selected goods as many times as you need.
Important note: Even if you want to order more varieties from this link, you must first set all selection fields to "select".
3. Do not pay separately.
If you plan to purchase multiple or different items, it is best to use the "Add to Cart" function until you have completely selected all the items and sizes you need before completing the purchase.
In the same way, no matter what you buy or how much you buy, the transportation cost will only be automatically calculated once (the logistics charge of some products may be different, and the details are subject to the interface display. If you are not sure, contact customer service in time).
