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.

Modular Rack & Pinion System
The Modular Rack & Pinion System is the primary building block of a linear axis drive. This system consists of a standard range of straight (spur), circumferential pitch, and helical racks and pinions. The modular design permits rack segment lengths from 0.5 to 2 meters to be linked together end to end achieving any desired travel length from standard components.
Racks and pinions are available with different materials, heat treatments and quality levels to insure the correct balance of power, precision and price to meet the application requirements.

The new benchmark for electrical preload on demanding machine tool applications!
KRPX is the new version of REDEX ANDANTEX rack & pinion high-tech planetary reducers, offering cost effective, easy to implement and high performing solutions for moving column or gantry machine types as well as many other applications.
The KRPX housing is made of high quality spheroidal graphite cast iron. Its structure has been optimised with FEM analysis methods to avoid deflection during acceleration. Fixation is made by oversized screws to ensure a real still connection with the machine frame allowing the KRPX housings to be considered as an integrated part of the machine main frame.
The output pinions are machined to the same diameter as the shafts, allowing the best possible balance between transmissible torque and rigidity at the rack. In addition, output bearing consists of two preloaded and substantially oversized angular contact roller bearings.
This exclusive design offers exceptional compound stiffness which allows to dramatically decrease the radial bending (up to 60% of the overall distortion) and to increase the natural frequencies of the global Racks & Pinions drive systems.
Designed as an association of two high-tech planetary reducers, KRPX allows perfect mounting on both sides of the machine frame and enables true zero backlash when coupled with an electrical preload system.
Available in 3 standard universal sizes (2, 3 and 4) KRPX is very compact, a definitive advantage for helping implementation with respective pinion height not higher than 104, 127 and 148 mm.
With this new and innovative concept, the machine-tools designers can easily expect to exceed market standards with maximum feed capacity up to 105 000 N and stiffness on the rack up to 333 000 N/mm.

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.

large slewing ring pre-loaded for robotics and for applications where high stiffness and accuracy are requested
|
|
Our Antifriction Bearings comprise four race rings, balls, a ball cage and, on request, an enclosed construction.
Franke Antifriction Bearings are based on a patented principle: the four race rings fit their raceway thanks to a specially developed grinding procedure – exactly adjusted to the ball diameter. Therefore, the rolling process does not occur directly between the rolling elements and enclosed construction, but rather smoothly on the four open race rings.
This special construction principle produces an extremely compact bearing, which also suits very small spaces. Another plus: the low friction and high load capacity of our Antifriction Bearings reduce energy consumption.

We manufacture all kinds of slewing bearings ranging from diameter 400 to 6,000mm. Internal gears, external gears and non-gears are available.
-Four Point Contact Ball Slewing Rings

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.

Our slewing bearings are most widely used in various kinds of construction machineries, such as tower cranes, excavators, mobile cranes, other types of cranes, piling machines, and truck-mounted concrete pumps, etc. With the fast development of Chinese economy, national key projects are being started one after another and basic infrastructure projects are being implemented in ever more cities and townships. During this development process, more construction machineries will be needed, and so will be our products all around China.

RSM specialize in the manufacture of medium to large size slewing rings with a minimum 200mm bore up to 8,000 mm diameter as monobloc systems and segmental bearings up to 10,000 mm in diameter. We manufacture a full range of slewing bearings that cater for a variety of industrial, mining & materials handling applications.
RSM collaborates with a French company by the name of ATHOS in the production of all our slewing rings and while ATHOS is a relatively young company it certainly comes with a lot of experience and superfluous credentials. ATHOS is run by Pierre Bonhomme, a man that has been in the slewing bearing business since 1974. In his 35 years of experience he has run both ROLLIX DEFONTAINE & BRB TECHNOLOGIES.
ATHOS was pivotal in the successful selection of our manufacturing plant and oversees all technical aspects of production and quality control. RSM has worked and continues to work closely with ATHOS on all of the above aspects but our primary role is to deal with the commercial complexities of running the business including marketing our bearings and dealing with existing and prospective clients on a day to day basis. Together with ATHOS, RSM is able to ensure our clients receive professional service and a first class product at very competitive prices.
We have found a niche in supplying clients with bearings that are currently being offered with unmanageable lead times or at overinflated prices by your top brands, you will find RSM is a more than suitable replacement for your premium brand bearings such as Rothe Erde; Rollix; IMO; SKF; FAG; TIMKEN; NSK etc...
