Solid Shaft vs Hollow Shaft Gearbox
Solid and hollow output shafts solve different machine-interface problems. Hollow-shaft units can simplify shaft-mounted arrangements, while solid shafts suit couplings, pulleys and conventional driven-shaft connections.
Solid shaft
Often used with couplings, pulleys, sprockets or a separate driven shaft. Key dimensions include shaft diameter, extension and key.
Hollow shaft
Allows the machine shaft to enter the gearbox output. Key dimensions include bore, key/spline or shrink-disc interface, shaft insertion direction and axial retention.
For replacement work, a base size alone is not enough to prove hollow-shaft interchangeability.
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.
