Metric Gear Types
from KHK USA

Most Popular

Spur Gears

The most common gear type — straight teeth parallel to the axis. Available in modules 0.5 to 10, steel, stainless, and plastic.

400+Configurations

Low Noise

Helical Gears

Angled teeth for smoother, quieter operation. Ideal for high-speed, high-load applications in automation and robotics.

200+Configurations

Right Angle

Bevel Gears

Transmit motion between intersecting shafts. Available in straight and spiral tooth forms for right-angle drives.

150+Configurations

90° Drive

Miter Gears

Equal tooth bevel gears — transmit motion at exactly 90° between intersecting shafts at 1:1 ratio.

60+Configurations

High Ratio

Worm Gears

High reduction ratios in a compact package. Self-locking capability makes them ideal for lifting and positioning.

100+Configurations

Linear Motion

Gear Racks & Pinions

Convert rotational to linear motion. Spur and helical variants for CNC machines, automation, and gantry systems.

180+Configurations

Planetary

Internal Ring Gears

Teeth on the inside of the ring. Essential for planetary gearboxes, wheel drives, and compact power transmission.

80+Configurations

Non-Parallel

Screw Gears

Crossed helical gears that transmit motion between non-intersecting, non-parallel shafts at 90 degrees.

50+Configurations

Complete Units

Gearboxes

Complete gear reduction assemblies — right angle, in-line, and planetary for servo and motor applications.

120+Configurations

US Standard

Inch (DP) Gears

Diametral pitch gears for US-standard applications. Compatible with existing inch-system machinery.
