    What are slewing ring bearings?

    Slewing ring bearings are ready-to-install slewing rings for lubrication-free, dry operations. The design is not based on metal rollers or balls but on maintenance-free sliding elements made of the proven tribologically optimised iglidur® materials.
    This is in combination with rings made of lightweight anodised aluminium or stainless steel. iglidur® materials can be employed universally and enable use in applications involving high temperatures, moisture or contact with chemicals, as well as in the food industry.

    Quiet operation for slewing ring bearing PRT

    The igus® PRT slewing ring bearings with plastic sliding elements produce significantly less noise and vibrations. For you as an operator, plastic gears - for example in robots - lead to an application that is up to four times quieter.

    Resistant to chemicals and media

    Temperature
    Temperature

    Suitable for the food industry (FDA) and for daily cleaning with cleaning agents and high pressure. PRT slewing ring bearings are also an ideal solution for special applications with high temperatures of up to 180°C or ESD.
    The rings are made of plastic, aluminium or stainless steel.

    Tested and proven

    Icon tested

    Our in-house test stations are available for individual customer tests. We also test our slewing ring bearings daily for active research and development.

    Solar panel with PRT slewing ring bearing

    Efficient solar energy for motorhomes

    The company CityFreighter has developed the "Solartrackr", a tracking photovoltaic module that supplies motorhomes with self-sufficient electricity. The system automatically aligns itself with the sun and thus optimises energy generation. For reliable and maintenance-free movement, the company relies on lubrication-free iglidur PRT slewing ring bearings from igus, which work precisely even under demanding weather conditions.

    Personal robot

    When upgrading a customer robot, an iglidur PRT slewing ring was incorporated in the axis for the first time.An iglidur PRT-02-20 is now used in the rear axis of the robot. In order to optimally meet the requirements of EEVE, igus designed a custom solution with reduced required drive torque. It ensures that the rear wheel can rotate freely even in harsh operating conditions and without any maintenance.
