Dedicated to racks & pinions drive applications, the KRP+ design is based either on the use of one single unit or on the association of two top quality planetary reducers, mounted in parallel on the machine main frame.
When used as a SingleDRIVE, the KRP+ gives the benefit of an ultra high stiffness feed gearbox, dedicated to high performances rack & pinions drive systems.
When choosing the mechanical preload solution, the KRP+ become a DualDRIVE unit, which achieve the true backlash free feature by torsionally winding one pinion against the other through the rack.
Immediate benefits are to need only one motor, and to dramatically simplify the motor control.
When choosing the Electrical preload solution, the KRP+ is used as a TwinDRIVE unit, where the backlash is cancelled by the opposite torque balance between the two pinions, according with the two motors and drives remote control.

Nexen offers an advanced new technology that revolutionizes linear motion. The Roller Pinion System (RPS) provides zero backlash, very high positional accuracy, unlimited length, very high speeds, 99% efficiency, high rigidity, low noise, low maintenance, corrosion resistance, and long life. This opens up
new design possibilities and provides the capability to achieve much higher levels of performance in machine designs.
The RPS's unique design eliminates many of the limitations of current linear drive systems like:
Ball Screws: Limited by critical speed, maximum speed, cumulative error, vibration, thermal expansion, supplemental cooling, noise, low efficiency, maintenance, and life.
Traditional Rack and Pinion: Limited by low accuracy and speed, backlash, tooth fatigue, noise, high cost of dual and split pinion systems, high maintenance, and short life.
Belt Drives: Limited by low accuracy, backlash, low load capacity, short lengths, belt stretch, and low rigidity.
Linear Motors: Limited by low load capacity, high cost, strong magnetic fields, and liquid cooling.

Impressive though the success story of semiconductor lasers has been, there are still several spectral "gaps", wavelengths that cannot be directly accessed with laser diodes. However, nonlinear frequency conversion techniques can be employed to generate tunable laser radiation in the UV, blue and green spectral range. TOPTICA offers state-of-the-art laser systems based on second harmonic generation (SHG), sum frequency generation (SFG) and fourth harmonic generation (FHG).

Drive-in racking is ideal for homogeneous products with low levels of turnover and a high number of pallets per article type. This system offers the highest use of available space in terms of both area and height.
Advantages:
- Maximum use of available space (85%).
- Elimination of aisles between the racking.
- Rigorous entrance and exit control.
- Drive-in racking can generally accommodate as many article types as there are loading aisles.
Two management systems are available: the drive-in system, with only one access aisle, and the drive-through system, with access to the load from both sides of the rack.
The system is frequently used in cold stores (refrigeration and freezing) which require maximum use of space for the storage of products in a controlled temperature.
Drive-in racking can also be used in construction of clad-rack buildings whose most striking feature is that they do not require the existence of a building prior to construction.

Modern IS machines rely on Take Out Arms to efficiently and accurately transfer hollow glassware from the dead plate to the machine conveyor. When functioning properly, the take out arm is synchronized with blow molds and glassware is uniformly spaced on the conveyor. As production rates and line speeds increase, the proper functioning of the take out arm becomes especially critical.
- Fully compatible with most IS machines
- Built in overload protection option
- Maintenance free
- Greatly improved drive life
- Complete drive or retrofit kits available
- Reduced downtime and maintenance
- Suitable for 4.25" to 9.25" bottle spacing

Plug and play: immediately useable
Ratio-Drive® from Hänchen is a self-contained, ready-to-use system solution for practically any application. This high-performance regulated linear drive is the sum of „standardised“ components in combination with the attendant mechatronic services. It is tailored exactly to your needs. As a user the only thing that you have to provide is the hydraulic and electrical supplies.
Independently strong – unbeatable in a team
Without doubt the cylinder is the heart of every Ratio-Drive® system solution. Every user can call on its application as a single cylinder or as several cylinders within a self-contained circuit. In order to be capable of presenting an individual solution in the form of a system, the cylinder requires reliable ”system partners”, as only the practical combination of cylinder, components and mechatronic services can provide an individual and simultaneously effective solution. This includes the mechatronics (every Hänchen cylinder with integrated linear positioning system is a part of a Ratio-Drive® system solution), electronics, the corresponding valves, the control unit and power supply.
