Standard spur gears are the workhorse of mechanical power transmission, efficiently transferring motion and torque between parallel shafts. Their straight-cut teeth are parallel to the axis, meaning they generate no axial thrust, simplifying bearing requirements. While they can produce more noise than helical gears, our precision manufacturing capabilities-using advanced hobbing and CNC machines-minimize this by ensuring exceptional tooth accuracy and surface finish. This results in smoother, quieter operation and longer gear life, even for high-volume orders.
Gear position: external gear
Manufacturing method:cut gear
Tooth shape: spur gear
Material: Alloy/Carbon Steel
Type: circular gear

Gears can be categorized using straight teeth (Spur Gear).
Based on how two gear axes are positioned in relation to one another
Given the orientation of the teeth (two parallel or not),
It is separated into rotation of space gears and plane gears;
based on how the equipment is operating,
There are two categories for it: open transmission and closed transmission.
in accordance with tooth profiles or gear teeth The form is separated into erect teeth,
straight and curved teeth, herringbone teeth, or helical teeth.
