Helical Rack Gears - L Configurable (One End Machined)

Click on this image to zoom in.

Features: Helical rack gears have a higher contact ratio than straight rack gears, resulting in superior transmission accuracy and quieter operation.
The 19° 31' 42" helical angle has a CP (circular pitch) front surface pitch, which makes it easy to design and position.
The helical rack gear is becoming the world standard in helical angles, mainly in Europe.
