F series helical gearbox is made up of 2 pairs or 3 pairs as reduction system.it has more output installations compared with R series because it can be hollow shaft output type.

The gear treated by the carburize quenching, the surface hardness is about HRC58-62, quenching depth is 0.2-2mm

F series widely used for many industries, such as petroleum, metallurgy, mine, lifting, transportation, cement, chemical, textile, printing pharmacy, food and environment protection.

Advantages:

Parallel output, compact construction, high torque transmission, stable working, low noisy and long lifetime. F series helical gearbox is made up of integrated casting box strong housing construction to improve the strength of the shaft and lifetime of the bearing, high torque output and high loading permited.
