We provide the complete alpha solution through project engineering and the supply of all necessary system components from one source.
Rack & Pinion overview
- weight and space-saving mounting method
- all mounting surfaces ground to tight tolerance results in
flexible mounting options
- optimised smooth and low noise level
- high reliability due to wear-resistant surface treatment
and individually deburred gear teeth
- maximum possible feed dynamics with short
acceleration times
- maximum precision for lifting axes
- maximum operational safety due to high overload
capacity
- Quality 5 (AGMA-11) through permanent checks
according to DIN 9001
- ultra-high linear accuracy |

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.

INA slewing rings are known worldwide as premium products in the field of rolling bearing technology. These machine elements have proved themselves many times over, have high load carrying capacity, a versatile range of applications and are highly cost-effective. Due to their design, a single bearing can reliably support radial, axial and tilting moment loads. It is therefore possible in many cases to replace bearing arrangements comprising a combination of radial and axial bearings by a single bearing. This reduces, in some cases considerably, the costs and work required in the design of the adjacent construction and the fitting of bearings.
Slewing rings are sealed on both sides, lubricated with a high quality grease, can be relubricated via lubrication nipples and are particularly easy to fit. The bearing rings are supplied without gear teeth or, in order to achieve simple drive solutions, are available with external or internal gear teeth. |

he David Brown worm gear range comes in Single Reduction worm gears which are based on a single universal case for each size, giving a high degree of common parts and interchange ability. Our Double Reduction worm gears are ideal for fitting to slow moving machinery and are constructed using two single reduction worm gear units connected together.
David Brown worm gears are also available for washdown environments and can also be shaft mounted units which are directly mounted to the driven shaft dispensing with connecting couplings and baseplates . The standard and Heavy Duty worm gears are ideal for stirrer and cooling tower units where a larger lower bearing and increased shaft size are needed to add extra unit capacity and absorb higher shaft and bearing loads. |
