F series parallel shaft helical transmission gearbox speed reducer
1. Housing with tendon are made of cast iron to get high strenth and fine heat loss.
2. Gears made of forge steel and finished through gas carburising process and precise grinding to achieve
High precision and high efficiency.
3. Carburized gears are durable and highly accurate.
4. Flange-mounted with hollow shaft, foot-mounted with hollow shaft, and optional torque arm and other special accessories.
5. Large strength, long service life.
6. Large output torque, smooth startup, high efficiency.
