Output / Motor interface Output There is a choice of two different output variants. The standard long bearing base output flange version is used for beltdrives, allowing high cantilever forces. For the 2K 300 an extended output version is optional for even higher belt forces. Further options include short output housings as ZF Duoplan INLINE for space saving direct drives. This version is supplied as a standard with angular contact bearings. ZF Duoplan TSC (Through-Spindle-Cooling) allows cutting liquids like emulsions, hydraulic oils and airoil mixtures with up to 70 bars of pressure at a flow...

Sealing with motor shaft seal. Closed design (with hub bearing and shaft seal) There is a version with ball bearing available for certain motors. The hub in this version is also fixed by the bearing to prevent axial hub movement, rsp. present axial forces from the helical gearing onto the motor shaft (see technical data page 7).
