What Is Gearbox Service Factor?
Service factor is a selection margin used to account for duty severity beyond nominal power and torque. It should be considered with operating hours, starts, shock load and driven-machine behavior.
What changes the required service factor?
- Daily operating hours
- Number of starts and stops
- Smooth, moderate or shock-loaded duty
- Driven-machine inertia
- Reversing or cyclic operation
- Ambient and process conditions
Selection mistake to avoid
Do not choose a gearbox because its nominal torque barely equals the calculated load. The selection should reflect the actual duty and required margin.
How this applies to R, F, K and S gear units
The same engineering principle applies across the CHINFAR four-series platform, but the mechanical layout changes: R is inline/near-inline, F is parallel-shaft, and K/S are right-angle families. Use the principle to define the requirement, then select a configuration within the appropriate family.

Precisa de uma configuração de redutor para sua máquina?
Envie a potência do motor, a velocidade de entrada, a velocidade de saída ou relação alvo, o torque de saída esperado, a disposição de montagem e qualquer desenho de instalação disponível. A CHINFAR pode usar essas informações para estreitar a configuração R/F/K/S antes da confirmação final de engenharia.
