Standard Spur Gears
Spur gears are one of the simplest and most widely used types of gears. They are characterized by their straight teeth that are parallel to the axis of rotation.
Change Gears
Interchangeable gears used in machine tools to alter speed or feed rates, enabling flexible and precise operational adjustments.
Drawn Pinion Wire
Continuous gear-toothed wire stock, cold-drawn for strength and precision, easily cut into multiple identical pinions for manufacturing.
Internal Gears
Gears with teeth cut on the inner surface, meshing with external gears for compact power transmission in enclosed systems.
Stem Pinions
Small precision pinions cut directly on shafts, widely used in compact mechanical assemblies and precision drives.
Standard Gear Rack
A gear rack is a linear gear that meshes with a pinion gear to convert rotational motion into linear motion. It is an essential component in various mechanical systems, providing precise and controlled movement.
Miter Gears and Bevel Gears
Standard Bevel Gears
Bevel gears are used to transmit motion between shafts that are at an angle to each other, typically 90 degrees. They are characterized by their conical shape, which allows them to change the direction of rotational motion.
Spiral Bevel Gears
Conical bevel gears with curved teeth for smooth, high-load torque transmission at intersecting shafts.
Standard Miter Gears
Miter gears are a special type of bevel gear used to transmit motion between shafts that intersect at a 90-degree angle. They are characterized by their equal-sized, conical gears, which allow for a direct change in the direction of rotation.
Spiral Miter Gears
Bevel gears with curved teeth for 90° intersecting shafts, providing smooth, quiet torque transmission and precise angular motion.
