The precise linear actuators from norelem represent a standard solution available from stock to automate linear movements with ease. They are suitable for use in production, assembly, packaging, logistics, and storage lines or on special industrial machines. A toothed belt drive ensures smooth and synchronous transmission even of heavy and constant loads.

The linear actuators, sometimes also referred to as linear axes, with toothed belt drive and profile rail guide offer customers many advantages: they are compact and light, but at the same time convince with very high rigidity. The toothed belt drive ensures a smooth, synchronous drive. «Toothed belt drives are used in positioning drives, among other things, because they work reproducibly due to the positive coupling,» explains Marcus Schneck, CEO of norelem. «In addition, they can be designed to be largely backlash-free. In this case, the toothed belt drive is used as an actuator.» Thanks to the sealed bearings, this results in low maintenance for norelem’s linear actuators. The belts themselves are easily accessible, so users can easily adjust the tension or replace them if necessary. The standard stroke lengths are up to 1960 mm, but on request the linear actuators are also available in special lengths up to 4000 mm.
The base body consists of a self-supporting extruded aluminium profile with integrated profile rail guide. It is a standard profile of series I with the dimensions 60 x 60 mm or 80 x 80 mm. The rail system can absorb the highest forces from all directions, is low-wearing and offers optimum running when moving large masses. There are grooves on the outer sides of the aluminium profile for easy and safe mounting and for attaching accessories. The groove width is 6 or 8 mm. Due to the symmetrical design, the linear axis allows motors and gears to be mounted on all four sides of the bearing housings. The aluminium slide of the linear guide has four threaded holes for mounting additional elements. Additional centring holes enable precise mounting.

Toothed belts reinforced with steel tension members enable high power transmission and, at the same time, high positioning accuracy. The toothed belt runs in guide grooves on the top of the aluminium profile and thus protects all parts in the profile from dirt.

Bespoke harsh environment connector solutions set Omnetics apart from competitors

Electronic connector experts Omnetics sets itself apart from more traditional suppliers by collaborating closely with customers, and by getting to know their specific needs and challenges to build bespoke solutions that really work.Get more news about Harsh Environment Connector,you can vist our website!

The company’s collaborative approach is perhaps most effective when working to create “harsh environment” connector solutions. These are often bespoke solutions, built for customers in key sectors like aerospace, defence, energy and medical, which, due to their application, must be enhanced with special features to ensure they continue to work effectively in extreme, or “harsh”, environments.

Harsh environment connectors may be required to work at very high temperatures, for instance, or be able to withstand repeated shock and vibration. Some harsh environment connectors must work well at high speeds, or altitudes, like those within aerospace or space sector applications. Others, meanwhile, need to be especially resistant to dirt or moisture ingress, like those in military or oil & gas sector applications.

Travis Neumann, Special Projects Manager at Omnetics, considers harsh environment connectors to be any needing enhanced features that don’t fall within normal military (MIL) standards for connectors. “Our connectors are made to standards MIL-DTL-83513 for Micro D’s, and MIL-DTL-32139 for Nano D’s,” he says.

“When we talk about harsh environment connectors, for me that means solutions that have requirements above and beyond those industry standards. It might mean the customer needs connectors with a wider temperature range than -40 to 125°C, for example, or they may need additional sealing requirements to increase resistance to dust and moisture ingress.

“If the connectors are going to be on board a ship, and need to work at or near the sea, for instance, the customer could need additional corrosion resistance. Or, if the customer is an aircraft operator, they may have greater EMI-shielding requirements. These are all common customer needs when it comes to harsh environments.”

Establishing exactly what the customer needs from their solution can be the hardest part of the process of designing, manufacturing, and then delivering a successful harsh environment product. Omnetics works on a case-by-case basis, taking the time to truly understand a customer’s challenges and emphasising the value of clear and open communication.

“It all depends on the customer,” says Scott Fitzharris, Design Engineer at the company. “Some already know everything they want from their product, and arrive ready with a checklist for us to work through. Others can’t tell you a lot about their needs but can at least say where the product will be applied, and how it needs to perform.

“Then, some customers know they need something but don’t specifically know what that solution is. That’s when you really do have to collaborate. If the customer can’t provide enough information, we’ll work with them to find a solution. We may build them a sample, for example, just to try it out. Our customer can review the aspects and provide feedback to those which did or didn’t perform well. Then, we can change the specifications until we get the right results.

To emphasise the complexities of building bespoke connector solutions for certain harsh environments, Fitzharris provides an example of working with a company in the aerospace sector. “The customer came to us and just said they needed EMI (electromagnetic interference) shielding, and that’s it,” he says.

Comparing Modular Linear Actuator Drive Types

With Nook's modular linear actuators, there are no limits in the variety of possible configurations. For several decades we have helped a huge number of customers with very special linear motion requests. Our customers receive customized solutions for a wide range of drive types and guides.Get more news about linear drive,you can vist our website!

These modular linear actuators are found in virtually every area of the automation industry. Our customers value their performance in processes ranging from simple positioning tasks to highly complex multi-axis systems that require great precision.
There are typically four main drive types for these linear actuator systems. While there is some common functionality, each method can have several distinct advantages for a given individual application. We will explore each of the drive types in further detail here.

Belt Drive

Linear actuators with "toothed" belt drive are designed for high-speed motion over long distances. They are perfect for fast positioning and handling tasks involving light to heavy loads in which high repeat accuracy with short cycle times are also vital. The drive is provided via a steel-reinforced toothed belt.

With standard accessories, these linear axes are easily combined to create multi-axis systems. Our innovative technology keeps wear in the units to a minimum providing longer service life. They offer a much lower cost solution as compared to linear motors.
Screw Drive

Linear actuators with screw drive are preferred for high axial thrust forces, where the highest precision is also required. They offer a convenient and exact solution. Screw drive makes it possible to generate high feed forces and are particularly suitable where there are stringent requirements for positioning and repeat accuracy. You can choose between acme and ball screw types.
Rack & Pinion Drive

Linear actuators with rack and pinion drives are used for highly dynamic movements with long distances. Even with heavy loads, they offer constant positioning accuracy. They also provide greater feed forces in long strokes. This solution gives you high stiffness, excellent positioning accuracy, and high load capacity.

The racks and the rack wheels deliver a very long service life. Any number of rack segments can be connected together, allowing unlimited lengths. Furthermore, several carriages can be operated independently of each other on the linear unit (saves time while increasing throughput).

Flint Group Flexographic Introduces new nyloflex® FTL Digital Flat Top Dot Plate

With nyloflex® FTL Digital Flint Group announced the launch of a very low durometer flat top dot flexographic printing plate for printing on sustainable substrates with a higher content of recycled fibers and other paper and board applications in combination with water based inks. The core advantage of this new plate is the out-of-the-box reliable performance in fluting reduction in corrugated post-print e.g. delivering a very appealing print performance on substrates like uncoated test liners or kraft liners in combination with a B flute.Get more news about Flexographic Flat Printer,you can vist our website!

From the beginning, printing on corrugated board has been troubled by the fluting phenomenon. Apart from other factors, the liner quality is one influencing variable. Another one is the dot shape of the printing elements on the flexo plate. “Flexographic plates with flat top dots, in contrast to common digital plates with round top dots, can reduce the unwanted fluting effect”, explains Dr. Eva Freudenthaler, VP Technology at Flint Group Flexographic.

Aiming for the highest print quality and hence lowest fluting effect as well as for a very good solid ink density (SID), the nyloflex® FTL Digital is able to reduce operating costs and waste. It provides the possibility to use more recycled fibers in the substrate without sacrificing on print quality. Because of the combination of screens and solids on a single plate even on difficult substrates, it is possible to save plate material by up to 50% and reduce press setup time to register the plates. The inherent capability of the plate to form flat top dots with simple UV-A tube exposure keeps the plate making process simple and cost effective as neither extra steps like plate lamination nor extra consumables or special FTD exposure equipment are required.

“Since the launch of the nyloflex® FTC Digital in 2017 we already offer a valued flat top dot plate to the corrugated post-print market. It has proven to be very versatile with respect to substrates that it can cope with, delivering excellent highlights in combination with good fluting reduction. Due to its higher durometer it naturally reaches its limit though at the lowest end liner qualities”, explains Dr. Freudenthaler. “That is why we have supplemented our plate portfolio with the nyloflex® FTL supporting the continuing trend to more cost effective liners”.
