3 xiros ball bearings pplication examples Other exciting applications GUIDE ROLLERS The xiros polymer ball bearings are 50 % lower in price than the bearings previously used here THERMOFORMING MCHINE In this Thermoforming machine for coffee-cream portion packs, xiros 500 plastic ball bearings are used for their high chemical resistance. (frischli Milchwerke GmbH) INDEXING TBLE This indexing table is used to test metal balls for cracks and dimensional accuracy. xiros polymer ball bearings are used here as wheels for the trolleys. WET FILM THICKNESS GUGE This precision tester for accurate and rapid measurement of all liquid paint, coatings, oil coatings and adhesives is equipped with a durable and solvent resistant xiros B180 ball bearing. FILM GUIDE ROLLERS There is no contamination of the films through lubricants, due to the use of maintenance free xiros flange bearings. EXTRUDER ROLLER fter clarifying the corrosion characteristics of stainless steels, we were able to successfully conduct tests and installed our xiros polymer ball bearings as drop-in replacements for the stainless steel bearings, which resulted in a significant increase of the service life. THREE-SIDED TRIMER The xirodur B180 radial grooved ball bearing is used in a three sided trimmer made by Perfecta Schneidemaschinenwerk GmbH. xiros polymer ball bearings are usedto transport books, brochures, magazines, or newspapers to subsequently cut these into the proper format. 720 Lifetime calculation, configuration and more 721

The maintenance free dry-running and the use of xirodur high performance polymers successfully solve many applications where conventional metal ball bearings are not effective. xiros ball bearings are the only plastic ball bearings in the world which use specially developed xirodur tribo-polymers. Lubrication and maintenance free High corrosion resistance Free from metal (due to the use of glass and plastic balls), therefore non-magnetic For temperatures up to +150 C High chemical resistance, suitable for washdown Light weight Electrically insulating (or conductive) FD compliant (depending on material) Predictable service life Typical application areas: Packaging Textile industry Test engineering and quality assurance Optical industry Model making Medical technology Online product finder xiros ball bearings Product overview xiros radial deep groove ball bearings Lubrication and maintenance free Corrosion resistant Chemical resistance Predictable service life Light weight From page 728 xiros radial deep-groove ball bearings further designs Lubrication and maintenance free Corrosion resistant Chemical resistance Light weight From page 740 xiros axial ball bearings For absorbing axial loads xirodur B180 combined with glass or stainless steel balls Temperature resistant up to +80 C From page 748 Polymer ball transfer units for lubrication free transport of sensitive products Page 750 xiros in combination with igubal for maintenance free use in conveyor belts and cam rollers Page 752 max. 150 C min. -40 C 7 Materials 17 product types Detailed technical data From page 726 vailable from stock.

5 xiros ball bearings xiros ball bearings Design Other designs Development and tests Predictability The xiros polymer ball bearings are single-row grooved Through numerous tests the race materials were optimised. s part of the development of xiros polymer ball bearing ball bearings based on DIN 625. The lubrication and xiros radial deep groove ball bearings The polymers we have developed for use with ball bearings tests are carried out continuously. The high number of test maintenance free ball bearings consist of four components: The other designs include convex rollers, which can run allow higher speeds, greater loads, and longer service life. results make it very difficult to present this information in directly on a profile, castors, a multi-bearing for linear But the development continues, we believe that polymer ball tabular form. It is for this reason that igus has developed The outer- and inner races and radial movements, flange bearings designed e.g. bearing technology will continue to advance, especially with the online life calculator, which uses real test results to give The suitability of a xiros polymer ball bearings is largely for installation in tube ends and double-row bearings for our experience and development with tribological polymer an accurate calculation. determined by the materials of the two races. These are absorbing higher forces. materials. Challenge us, talk to us about your applications, made from igus tribopolymers to maximise service life tell us what you need from a plastic ball bearing. In the The predictability of xiros polymer ball bearing is one of and minimise friction. You can currently choose from six Pillow block and flange bearings igus test laboratory the life and wear of xiros polymer the most important advantages. Based on the results of different materials. They allow different values of application This range is made up by combining xiros polymer ball ball bearings are tested. In addition to the actual material many wear tests, the user can calculate the service life of temperature, chemical resistance and price. The table with bearing with the igubal pillow block and flanged housings, comparison, tests indicate these experiments also answer the xiros polymer ball bearing reliably and interpret the material data ( page 726) gives exact information. resulting in a higher flexibility in terms of installation of the questions about the impact of external influences such as application. Outer race bearings. The pre-finished bearing housing make it easy for the user to use these maintenance free components. temperature, humidity or dust. Both flanged and pillow block are available as fixed or as Inner race pivoting design.the difference between the two options is that the pivoting type can compensate for shaft and/or bearing misalignment. spherical outer race is pressed Cage into the bearing housing, ensuring self aligning action. If necessary, the inner bearing can be pivoted in all directions. Balls Possible misalignment of two bearing points lying together can thus be compensated. The cage The material of the ball bearing cage must fit well to the application. The various material options have quite different chemical and temperature resistance values. The cage materials are compatible with all the different race options within xiros. The balls The ball materials differ most significantly. In addition to steel glass or plastics are used. This produces a large difference in mass, which in turn affects smoothness, weight and chemical resistance. Steel balls (stainless steel) Two of our test benches for xiros polymer ball bearings are costeffective, chemical resistant, but with the highest at igus bearings laboratory weight. Glass balls are used to give a metal free solution. They are also very resistant to chemicals and have an average weight. Polymer balls have significant advantages in weight, size and quiet running characteristics. Depending on the polymer used, plastic balls they can have excellent chemical resistance. 724 Lifetime calculation, configuration and more 725
