1. Efficiency

Miter Gear Box and ARA Gear Box use high-precision spiral bevel gears, ensuring high efficiency.

(1) ED2 ~ ED12:98% (2) ED16 ~ ED25:95% (3) ARA3 ~ ARA6:98%

However, this will vary depending on the rotation speed, ambient temperature, and load factor.

2. Backlash

This is the total amount of mechanical clearance that can be measured in the rotational direction on the cross shaft when the lateral shaft is fixed.
