Special note
:
※ 1.5 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.
The average price will be cheaper if you buy a large quantity than a small quantity!
