Design engineers tasked with designing and developing robots, rotary tables, machine tools and many other types of automation system come up against the same challenge time and time again: the need for a rigid precision bearing in the tightest of spaces.

HIWIN has come up with the ideal solution in the form of its CRB series of crossed roller bearings.

The crossed arrangement of the rollers at an angle of 90° means that the bearings are able to absorb not only axial forces from both directions but also radial forces and tilting moment loads, as well as any load combinations they might be exposed to.

The secret behind the bearing's load capacity is hidden deep inside it. Thanks to their specific geometry, the spacers located between the rollers save a great deal of space, enabling more rolling elements to be packed into the bearing compared with similar models. The special design of the spacers also minimises the points of contact with the rollers and, as a result, friction losses.

The advantages over angular ball bearings or bearings with two bearing positions are obvious: HIWIN crossed roller bearings are much more compact and can therefore be installed in the tightest of spaces. They also score highly where rigidity is concerned. The linear contact of the rolling elements makes the crossed roller bearings three times more rigid than conventional ball bearings.

HIWIN offers its crossed roller bearings in five different models, two preload classes, three accuracy classes and with or without an optional seal – providing the perfect match for any application.

Offenburg – The precision delivered by HIWIN's LMX linear motor axes and their long service lives have established them as a popular choice among manufacturers. Now, the Offenburg-based specialist in linear technology is setting the bar higher than ever before in bringing its new generation of LMX axes to the market, with even more powerful motors and a more compact axis structure.

These axes represent the second generation of the equipment and use a new type of motor technology with a higher force density. This has made it possible to reduce the height of the system by some 40 % compared with the previous generation, allowing users to take advantage of more compact structures for their machines and pack more functions into the same amount of installation space.

All of the key components in the system are produced by HIWIN in-house, and this has given the manufacturer freedom to introduce new production processes and boost the mechanical precision of the axes even further.

The positioning measuring system and its sensors have been relocated to the protected axis interior, making the system more resilient as a whole. This also means that the axis can last up to 50 million cycles before requiring maintenance, if the operating conditions allow it.

With all these features, the second generation of LMX axes is continuing to set new standards in straightness, flatness and precision. It is the perfect choice for even the most demanding positioning applications, such as 3D measurement systems, laser processing machines or semiconductor production facilities.

The new linear motor axes are available now.

Offenburg – Linear movements involving ballscrews can now be com­pleted even faster and more dynamically than ever thanks to the new flanged single nuts from HIWIN's DEB-N series. The Offen­burg-­based electro­mechanical drive technology specialist has achieved these great advances by overhauling its successful DEB series. A key feature of the DEB-N product family is an innovative ball guideway which allows the load to be distributed to a larger number of balls, significantly increasing the resilience and service life of the ballscrew. A ballscrew featuring these new flanged single nuts can last up to twice as long as the previous generation – yet not a single change has been made to their external geometries. At the same time, HIWIN's engineers were able to improve running performance with the new ball guideway, enabling the nuts to run much more quietly and increasing the maximum permissible speed.

Every detail of the new nuts has been carefully considered: as the wipers can be replaced, design engineers can tailor the ballscrews to the environmental conditions of their application. NBR wipers are included as standard. The material is highly resistant to oils, greases and hydrocarbons, and its low rate of wear enables it to achieve a long service life. Alterna­tively, felt wipers or additional finger wipers are available as an option.

As a result, the new DEB-N nuts are suitable for universal use and are ideal for conveying and positioning tasks in the plant and mechanical engineering sectors, as well as in transport and logistic systems, to name but a few examples. They are also particularly suited to applications which require highly precise, dynamic and reliable linear movements.

Ballscrews with the new flanged single nuts are now available from HIWIN and, on request, can be produced with machined ends and matching bearing units.

Electric actuators are becoming increasingly important in industry, mechanical engineering and automation. They combine mechanical force with electrical precision and impress with their low-maintenance operating characteristics. Thanks to their versatility, our electric actuators can be used in a wide variety of application ranges. Where exactly? We have compiled the most important ranges for you.

Pressing and joining processes: When pressing bearing bushes, bolts and seals, as well as when joining metal and plastic parts, our electric actuators enable exact pressing strokes and pressing forces with high precision and repeat accuracy. Precise force control and process control ensure that every process step runs precisely and reliably. At the same time, they save energy and reduce maintenance effort.

Bending processes: In automated production lines, electric actuators support the bending of pipes, wires or sheet metal parts with variable radii. They also enable adaptive bending processes with material recognition. This allows the force and position to be dynamically adjusted for different materials. This increases flexibility and quality in production and supports highly automated processes.

Lifting and positioning systems: Electric actuators are used for height adjustment of work tables, palletising or packaging systems. They move loads in assembly lines or test cells reliably and energy-efficiently. Integratable safety functions ensure that positions are held reliably even in the event of a power failure. In sensitive ranges such as medical technology or food production, they work hygienically and reliably reproducibly.

pick&place: Electric actuators enable precise pick-up and deposit positions for handling tasks, even with small or sensitive components. Dynamic control allows for short cycle times, while integrable sensor technology ensures position and status feedback.

Food and beverage industry: Electric actuators perform precise labelling, even on irregular or moving objects. They enable a constant, adjustable pressure force to prevent damage or deformation of sensitive packaging. Their flexibility also allows quick changeovers for different product sizes.

Packaging industry: Electric actuators are used in packaging machines to erect and fold cartons or close lids. The movements can be easily reprogrammed without the need for mechanical modifications.

"Our electric actuators offer a unique combination of precision, efficiency and flexibility, combined with low maintenance. They are not only an innovative drive solution, but also open up new possibilities for automated processes in almost all branches of industry. They can therefore set a new standard in modern manufacturing and automation technology," explains Ilja Dreher, head of development for the new HIWN electric actuator.

With our online configurator, you can easily customise your electric actuator and order it in just a few minutes – directly, efficiently and without any detours. Configure it here now.
