Slewing ring bearings

What are slewing ring bearings?

Slewing ring bearings are ready-to-install slewing rings for lubrication-free, dry operations. The igus 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.

Cost-effective

Manufacturing with injection moulding guarantees cost efficiency and creates the geometrical freedom to optimise use of installation space. Thanks to the flexible modular system, the slewing ring ball bearings can be extended as required.

Lubrication and maintenance-free

Lubrication-free
Lubrication-free

The iglidur® PRT slewing ring is designed as a ready-to-install solution, so it is ready to use straight away and requires no additional lubrication or maintenance. This saves time and reduces maintenance costs.

Up to 60% lighter

Quiet
Quiet

The iglidur® bearing technology impresses with ultra-light materials, such as plastic and aluminium. This enables you to achieve greater efficiency in your application.

Quiet dry operation

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.

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.

TV mount with PRT slewing ring bearing

TV mount with iglidur® PRT slewing ring bearing

The PRT slewing rings can withstand a static axial load of 27,000 newtons and a dynamic axial load of 7,000 newtons. 
The TV mount can also be pivoted, telescoped and rotated up to 360° at the same time. The mount impresses with its innovative unique selling points, such as freedom from lubricants to avoid contamination of technical devices, as well as freedom from maintenance and quiet operation for optimal convenience.

    • Personal robot

    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.
