Make your own polymer rotary tables in the size of your choice

With the help of the flexible iglidur J universal sliding element from the igus, the user can now tailor the desired size of his rotary table bearing. Polymer rotary table bearings (PRT) from the igus exist in seven sizes and three types. There is also an igus PRT with quadratic flange for direct assembly on a flat surface.

iglidur PRT is a rotary table bearing with the proven advantages of igus polymer plain bearings. The sliding elements made of the tribo-optimized plastic iglidur J run totally maintenance and lubrication-free. The counterfaces of the rotary table bearing are mostly made of aluminium and are hard-anodized. As a result they also have very good tribological and sliding features.

Install and forget
Rotary table bearings are often used for slow pivoting and rotating motions that are operated manually: The ready-to-install rotary table bearings have a self-locking effect, for example in case of pivoting control panels of machines. At clocked movements in assembly lines, they work perfectly for a long time, no matter how often the movement is performed.

iglidur rotary table bearings – large, larger, infinite…
The smallest iglidur rotary table bearings have an inside diameter of 20 mm and the largest 300 mm. There are five other sizes are in between. igus engineers have now developed a flexible plastic universal sliding element with which rotary table bearings in most different sizes can be achieved: By putting iglidur J sliding elements together, rotary tables from an inside diameter of 500 mm up to almost infinite can be manufactured as desired. A rotary table bearing with a diameter of one meter that is built up on that basis can be loaded with up to ten tonnes according to its model. With it igus successfully managed the entry into large to very large rotary table bearings. Large rotary tables are particularly required in the solar technology, for assembly units or fixture construction. For such applications, igus not only delivers the sliding elements, but also supports the design engineer with information about precise dimensions and tolerances. With it the assembled bearing unit can be used immediately.

Rotary table bearing with square flange
All igus rotary table systems are wear-resistant, corrosion-free and easy to install – especially the new polymer rotary table bearing with square flange. It can be mounted on the flat surface with four screws only and without inlet holes. This avoids an additional distance ring. This rotary table has been designed for handling systems, the furniture industry and for display and advertising technology.

With many variants and flexiblity
Along with the seven sizes, igus rotary table bearings are available in three versions: a robust standard version also with mounted gear wheel, a cost-effective variant made of one element as well as light-weight low-cost-version with an inside diameter of 80 mm. For accessories igus offers in addition to manual clamp and drive journal distance rings for other sizes – optionally made of aluminium or plastic.

igus adds HD and motor variant to the e-spool series

igus further develops its offer of winding energy chain systems. The new igus “e-spool” heavy duty (HD) and motor flange versions are even more powerful. The HD variant is equipped with an extra strong spring to retract the energy chain at vertical applications. Moreover the motor version with motor flange is available for high filling loads and movements in any direction. The e-spool connects two energy supply systems into one system – a standard energy chain being wound and an igus twisterband for rotational movements.

No matter whether it’s, flat on or underneath the ground – the winding and space-saving energy chain system e-spool from igus is variably applicable in any directions. More importantly, e-spool is the only solution that guides all media types such as data, compressed air and liquids flexibly and with minimum space in one system. E-spool connects two different energy supply systems in one system – a standard energy chain guided via a reel that always supports the proper length and tension of the energy supply system and, an igus twisterband that performs rotational movements. This design allows movements in any direction, hence is suitable for a number of fields of application: process cranes, mobile crane trucks, sorting plants or stage applications.

e-spool module construction kit: three variants, three lengths and two versions
igus offers different e-spool solutions, depending on the pull out direction and load: The standard e-spool (SP) with a spring mechanism for spooling up the chain is appropriated for most applications and for any directions. Some vertical applications require a higher retraction force. Now the heavy duty variant (SPHD) comes into play: Here the retraction spring is stronger to be able to spool up the energy chain up to 14 m without problems. In addition, a motor variant with flange (SPM) is offered for especially high loads in any direction. igus delivers e-spool for the use with motor including motor coupling. The user installs motor and control.

All three e-spool versions are available in different extension lengths with 4, 7 or 14 m and one or two twisterbands in the standard program. The maximum spooling speed is about 1 m/s.

Modular alternative to the classic cable drum
The twisterband connects the reel with the shaft support, which serves as an interface to the permanently installed cables. This avoids the costly conventional slip ring that is usually used for cable drums. With it different cables can be connected, replaced or added any time within the smallest space in  a complete system. The twisterband gives the largest possible cable diameter of 17 mm and the minimal bending radius of 75 mm. For more capacity, twisterbands can be used on both sides of the drum.

igus measuring system cable is business class

igus has optimized its chainflex measuring system cables CF113.D and CF11.D: The new igus measuring systems cables have been further developed for smaller radii with a bending radius of at least 7.5 x cable diameter and dispose of accordingly high-quality superstructures. They are available from stock as yard goods or ready-made in 20 manufacturer standards.

Measuring system cables communicate the movement of a motor back to the control. They are used in any manufacturing machines for example in wood processing or in machine tools, but also in storage and retrieval units, in semi-conductor assembly or crane applications. For this reason five different qualities of measuring system cables are available in the chainflex program. Because, for as many applications possibilities there are as many motor manufacturers that want delivery. At the customers choice, a broad spectrum of 40 core cross section combinations.

Variety for almost any measuring systems
The chainflex cable program from igus provides a grand range of measuring systems cables for the use in energy supply systems. The cables are equipped with a PVC & PUR outer jacket for medium and high stresses. As a high-end solution for maximum stress the customer can go back to a TPE jacket. In addition there is a cable series for torsion applications. According to the drive technology systems from 20 manufacturers all cables are offered as ready-made yard goods or with plug connectors. 760 cable versions result in combination with the different measuring systems cables.

New in the program are the optimized measuring system cables of the series CF113.D and CF11.D for small radii with a bending radius of at least 7.5 x cable diameter. Both products offer optimized stranding and shield structures for especially small spaces and a high-quality substructure with gusset-filling pressure extruded inner jacket.

High-end measuring system cables in PUR and TPE quality
CF11.D as well as CF113.D is developed for highest stress. Of the same high value is its cable structure: an especially durable conductor, inner and outer shield made of extremely bending-resistant copper shielding braid and an inner jacket made of TPE. With respect of the abrasion resistance the outer jacket has been especially optimized for requirements in energy chains.

The chainflex cable (FlexCable Application) CF113.D is shielded with an outer jacket of a low-adhesion and highly abrasion-resistant mixture on the basis of PUR. A highly flexible TPE outer jacket protects the chainflex cable CF11.D. Both measuring system cables are coolant-resistant, hydrolysis and microbe-resistant, halogen-free and PVC-free and also oil resistant – the CF11.D even against bio oil. This allows inside and outside applications – even for travels of 100 meters (CF113.D) up to 400 meters (CF11.D). Above that the CF113.D is flame-retardant and notch-resistant. It is in accordance with UL, CSA and NFPA approvals, which makes it interesting for requirements in machine tool building. chainflex CF113.D and CF11.D are standardized in accordance with the Desina-standard.
