Bevel gear units KS

The bevel-helical gear unit KS210 is designed as a compact drive unit for highly-dynamic applications. The requirements for operation with servomotors have been implemented accordingly.
During the development, attention was also paid to high operational reliability by generously dimensioned bearings and toothing design. Furthermore, the housing with an integrated square
flange on the output side offers maximum rigidity and can be universally installed or attached thanks to the symmetrical inline housing.

The drive is available with a solid or hollow shaft (if required with an optional clamping set). The output shafts are also optionally available in stainless steel or even with surface protection
matched to your application. These enable the use in wash-down applications.

An optional stainless steel housing (stainless steel gearbox, hygienic drive) is available for particularly high demands on the surface quality. Requirements placed on new gear concepts
were taken into account. Minimal circumferential backlash, high rigidity, low overall weight, high efficiency, maximum flexibility in connection with a universal mounting position are features
that allow the successful usage of the drive.
