Product Description
Product Overview
A gear is a product with teeth added around the circumference of a drive wheel. Gear transmission mechanisms are widely used for transmitting rotational motion, rotational speed, and rotational direction.
Product Feature
Feature 1: Spur gears can provide high transmission power, and the instantaneous transmission ratio is stable, making them suitable for high-torque transmission and conveying.
Feature 2: Spur gears have a fixed center distance and long service life, making them suitable for compact and highly reliable mechanisms.
Feature 3: MISUMI brand economy spur gears feature high-precision tooth profiles, with a precision grade of GB/T 10095-2008 Grade 8; shaft hole diameter tolerance is H7.

Usage Method
■ Intended Use for Spur Gears
Set Screw is not included in Untapped type products.
Selectable gear shapes differ depending on the number of teeth. Check the specifications table.
A round shaft hole specification means it does not have a threaded hole.

Precautions
(1) If there are requirements for rust prevention, give priority to products made of SUS304.
(2) When gears are used together, there will be backlash. The gear position relationship needs to be adjusted according to the on-site assembly situation to achieve optimal performance.
(3) For shaft hole specifications, when selecting the non-threaded type, the fixing screws are not included.
(4) The positional relationship between the keyway and the gear teeth is not fixed.
