Product Portfolio
Bevel Gear Units, Screw Jacks, Indexers, Bevel Gears, Cams
Bevel Gearbox ZZ-Universal-Line
- Every ZZ bevel gear unit is fitted with a palloid-spiral bevel gear assembly.
Our bevel gear units are distinguished by their fully machined rectangular housings. All screw jointed faces have threaded holes. The lubrication level and supply holes are variably located according to the installed position. The gearboxes are designed and sold as incomplete machinery according to the Directive 2006/42/EC of the European Parliament.- Design sizes: 8 (K080/K110/K140/K170/K210/K260/K330/K440)

Servogearbox ZZ-Servoline
- ZZ-Servoline KN has been designed as a bevel gear unit especially for high-dynamic servo drives in automation techniques. With the hypoid gearing, gear ratio’s of up to i = 15:1 can be covered in one stage. The design of the gear takes into account a weighting according to requirements, between pitting, fatigue fracture, the loading capacity on the root of the gear tooth and gear scuffing. The gearbox is suitable for operating in any optional mounting position. The output shaft can be in the form of a single or double-ended solid shaft, or as an extended hollow shaft with external taper lock assembly. The various combinations of shafts and flanges, provide facilities for all commonly used servo motors. The gearboxes are designed and sold as incomplete machinery according to the Directive 2006/42/EC of the European Parliament.

Indexing Gearboxes
- The perfect components for movements, cycling and positioning
All ZZ cam gearboxes are fitted with through hardened and ground cams. This is the basis for high precision, positive action and long service life. A cam set converts a uniform input turning motion into stepped or oscillating output movement, which can be optimized for every application. The housings made of cast – iron or aluminium are fully machined. The indexing units are designed and sold as incomplete machinery according to the Directive 2006/42/EC of the European Parliament.- Globoid gear boxes: 25 Types

Indexing Tables
- The perfect components for movements, cycling and positioning
ZZ-indexing tables have proven their worth in various applications as for example packing machines, print- printing machines or assembling systems. They allow a high controlled cycle time together with low maintenance effort. They are suitable for absorbing high axial forces as large torque and moments of tilt. Within dwell phase there will be an interlock which also permits sensitive process operations on the part – together with high repetition accuracy. The output shaft is provided with a machined surface to take up an assembling platform. The gearboxes are designed and sold as incomplete machinery according to the Directive 2006/42/EC of the European Parliament- Versions: - type RTX version with globoid cam for accurate applications which are complex in their motion sequence, distance between axis: up to 450 mm
- type XZ version with cylinder cam with large central output hollow shaft, distance between axis: up to 615 mm - Transmissions: Freely definable (Pendulum, 2-32 stops)
