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.

Bevel Gears
where precise positionning is required...
There are gears in different sizes and miscellaneous designs. Durability, load capacity and noise levels from a gear wheel set, i.e. the quality required, influence the gear design and the production processes.
Besides offering normal quality, we are specialists in producing gears to ever closer tolerances and in optimising processes and quality controls through our ongoing research and development activities.
Another advantage is our expertise in heat treatment. Härterei Tandler , our heat treatment plant, is situated right beside our gear and gearbox factory and is certified to ISO9001:2000.

Machining
The cutting of the concave helical ring goes from module 0.5 to 24, from a diameter of 10 mm to 1400 mm.

We manufacture welded toothed wheels for you up to a maximum weight of 3.5 t per unit / module 20. Welded toothed wheels can be viewed as being a good value alternative to the more costly cast versions. As a rule, we weld all weldable materials with the exception of aluminium. Depending on size and intended use, we manufacture toothed wheels with spokes, forged rings, etc.

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.

Dedicated to racks & pinions drive applications, the DRP+ design is based on the association of two top quality planetary reducers, mounted in parallel on an extra high stiffness universal frame.
When choosing the mechanical preload solution, the DRP+ 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 DRP+ 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.

Precision needle rollers have multiple uses in a variety of industries including automotive, truck, farm and construction equipment, two-cycle engines, outboard engines and consumer durables. Needle rollers are mainly used as bearing rolling elements to transmit torque and reduce friction. They can also serve as precision shafts or as precision locating pins.

Drawn cup roller clutches are one-way clutches comprising thin-walled, drawn outer rings with a series of ramps on the inside diameter, plastic cages, springs and needle rollers. They can transmit torques in one direction and are radially compact. The roller clutches are available with and without a bearing assembly.
Drawn cup roller clutches give very precise indexing, since individual spring retention of each needle roller ensures constant contact between the shaft, needle rollers and the clamping surfaces. They allow high indexing frequencies due to their low mass and therefore the low moment of inertia of the clamping elements. They also have a low free-wheeling frictional torque.
Drawn cup roller clutches can be used in a wide variety of applications, for example as indexing elements, back-stopping clutches or overrunning clutches. The drawn cup roller clutch fulfils the overrunning or holding function as appropriate.

Free wheel with a cage with contact elements running on races primarily measured in inches
|
|
In this product group only the clamping elements are supplied, assembled into a cage or retainer.
This must be mounted between supporting inner and outer races which may be formed directly in the customer’s component or machine.
The races should be manufactured from the correct material and to the required specification and the whole assembly supported by the existing shaft bearings which must absorb all axial and radial loads.
Suitable lubrication and sealing also have to be provided.

|
|
Free wheels with bearing incorporated, with same dimensions of bearings series 6200, available in version ZZ and 2RS
|
|
Free wheels with cams to be incorporated with obstruction radial reduced.
Couples from 48 to 460 Nm for tree of diameter 20 with diamètre50.
They count rollers of blocking between a line of balls and rollers, to combine dynamic heads, static, axial and radial.
Without maintenance, autonomous, lubricated with grease for normal conditions of use, they are used to lock a step back or to place from one drive to the other in a kinematics to multiple order.
External dimension identical to the bearings series 59.

The transmission is involved in the 2 directions of rotation and is locked in position. The origin of the movement can be manual or electric.
The bidirectional transmission involves the transmission towards the right-hand side or the left. If the movement of entry ceases, the irreversible one locks the transmission in the position of stop and the movement of exit is neutralized in the 2 directions.
|
|
Placed between 2 energy sources, the oversteer one couples or disconnects whatever the differential speed.
It is a relayage simple, instantaneous, autonomous, without control.
To 360.000 Nm, the active elements are with slopes, cams.
Under casing, lubricated with oil or grease.
During launching out of high-speed, the oversteer one disunites and protects slow speed.

Mink roller brushes (BW) - Individually configured roller brushes with shafts
Mink roller brushes differ from other Mink round brushes by virtue of their integrated shafts. Owing to the wide-ranging demands made on these brushes, especially in terms of shaft dimensions, there is no advantage in maintaining a stock range. Nevertheless, with our extensive experience in this area we are able to configure special brushes for you very quickly. On account of its extraordinary versatility the Mink Zick-Zack-System can frequently serve as the basis for a reliable solution.
Your advantage:
• Individual configurations for special purposes

Deburring and Roller Brushes
Use Deburring and Roller Brushes for a professional and perfect finish of cut edges. Diameter, filling material, measurements of the brush and the required bore are determined by the appointed machine and the work piece. We exclude any imbalance by evenly arranged filling material and the testing of every brush.
