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.

If you put together single sliding elements made of iglidur J, rotary table systems from an inside diameter of 500 mm up to almost to any size can be manufactured as requested. With a diameter of one meter, a load of up to 10 tonness is possible according to the model. (Source: igus GmbH)
