Product Descriptions:

The working principle of gear rack is to change the rotary motion of gear into the reciprocating linear motion of rack, or the reciprocating linear motion of rack into the return motion of gear.

The precision grinding rack has high-precision DIN 5. The tooth surface is finely ground by the NC gear grinding machine. All surfaces of the rack are ground, the module m1-m20 and the tooth top are trimmed, which is more suitable for high-speed operation.

Rack parameters are described as follows:

1. Accuracy grade: DIN 3962 (DIN 867) - l5e24 adjacent pitch error FR ≤0.003 mm;

2. Cumulative error FP≤0.035mm/m optional material of rack: 45; 42CrMo20CrMn;

3. Tooth surface hardness corresponding to different materials: 45 steel-hrc45 (medium frequency surface quenching), 42crmo-hrc50 (medium frequency quenching) 20crmnmo-hrc58-60 (carburizing or quenching).
