1、 Introduction to gears and racks
1. Industrial trends (especially in the fields of precision automation equipment and CNC machine tools)
The function of gears and racks has shifted from simple displacement or power transmission to precise positioning. By using high-precision gears and racks, precise positioning can be achieved even without an optical or linear ruler.
In terms of replacing ball screws:
The movement speed in gear and rack applications is much faster than that of ball screws, and the longer middle section of ball screws is prone to sagging, which is not conducive to high-speed and smooth movement.
Ball screws have length limitations, while gears and racks can be assembled into various lengths at will.
The ball screw is only suspended on the machine at both ends, while the gear rack is completely detached from the machine tool, and the gear teeth are synchronized with the thermal expansion effect of the machine tool, while the ball screw cannot.
Gears and racks are easy to lubricate and have a longer service life.
2. Industrial requirements
High precision, high speed, high strength, low noise, and high wear resistance.

2、 APEX high-precision gear rack characteristics
APEX is the only manufacturer in the world that strictly produces gears and racks according to the following specifications:
Geometric tolerances for all dimensions
Defined straightness, parallelism, and perpendicularity
Tolerance for helix angle and pressure angle
Defined tooth surface roughness
Defined tooth hardness and hardened layer depth

APEX is also a leading brand in the world that allows displacement to design and produce their own gears, racks, and reducers, and provides well coordinated high-quality transmission components to meet different industrial needs.

The function of gears and racks has shifted from simple displacement or power transmission to precise positioning. By using high-precision gears and racks, precise positioning can be achieved even without an optical or linear ruler.
The characteristics of fast movement speed of gears and racks, free splicing length, and synchronization with the thermal expansion effect of machine tools can completely replace the application of ball screws in precision automation equipment and CNC machine tools.

APEX gears and racks are divided into two series: straight teeth and helical teeth. When selecting, pay attention to distinguishing between them.
1. Modular series of gears and racks:
1 / 1.5 / 2 / 2.5 / 3 / 4 / 5 / 6 / 8 / 10 / 12

2. Rack Precision Series:
Q4 / Q5H / Q5 / Q6 / Q6M / Q8H / Q8 / Q9 / Q10

3. Connection method of gears:
