Helical rack and pinion CHTM10010-DIN8

carbon steelprecisionlinear

Product overview
The CHTM10010-DIN8 is a helical milled rack manufactured in S50C carbon steel, with a right-hand helix angle of 19°31′42″. Teeth are milled to DIN 8 quality; the part is supplied untempered. The rack is designed for moderate-precision linear transmission where increased tooth overlap and smoother engagement of helical teeth are required.

Applications

• Economical CNC machines and machine tools
• Automatic doors and access systems
• Light-load material handling and warehouse equipment
