Parallel Shaft Helical Gear Units
For SR F series parallel shaft helical gear units,the boxes are cast precisely by high steel material and processed at processing center;the gears are made of high-quality alloy steel,are treated with surface hardening and toothed;and the key parts are imported.
Material of gears and bearings:20CrMnTi/40Cr
Hardness of gears and bearings:58~62 HRC/217~255HB
Gear handling method:Carburizing and quenching treatment
Hardness of Tooth Surface 58~62 HRC
Core Hardness 30~42 HRC
MOQ: No MOQ
The whole parallel shaft helical gear units are small in volume,with great load-carrying capacity,steady running,low noise and high efficiency.SR parallel shaft helical gear units have reached the advance international level,can replace the same kind of products imported.
