2020 news – slewing ring bearings

PRT-04

Ideal for small installation spaces

The new PRT-04 slewing ring bearing is 60% lighter than its predecessor. The installation height has also been reduced by half, offering even more design freedom.

  • Saves at least 50% installation space
  • Up to 30% more cost-effective and
  • 60% lighter than the PRT-01
  • Available with diameters from 50mm to 300mm 
  • Wear-resistant, lubrication-free and maintenance-free iglidur sliding elements

PRT-04 with internal gearing

For even more compact drive solutions

The PRT-04 with internal gearing has a compact design and allows drive from the inside. It is therefore suitable for applications where the installation space is limited, where lightweight or a cost-effective solution is required. With the exception of the toothed inner diameter, all components and dimensions are identical to the standard PRT.  

  • Compact design
  • Lightweight
  • For small installation spaces

PRT-04 with locking mechanism

Stopmotion slewing ring bearings with defined locking points

Our new stop motion PRT in installation size 04 enables a defined latching at individually predefined positions. The PRT can be individually adapted to any application and is suitable for applications, for example an assembly table.

PRT-04 with angular stop

PRT-04 with angle stop

Determine and individually adjust the angular stops

The angle limit for the PRT-04 can be continuously adjusted. This means that the pivoting range can be determined individually for each application and can be precisely adjusted to within 2°.

  • Continuously adjustable
  • Angle range in 2° steps
  • Load capacity identical to standard type 04

PRT-04 ESD

With iglidur F2 sliding elements to avoid electrostatic charging

The PRT-04 made of stainless steel is conductive and prevents electrostatic charging. It is particularly suitable in areas where charging must be prevented, e.g. in the semiconductor industry or in laboratories.

  • Rings made of stainless steel and sliding elements made of iglidur F2
  • Prevents electrostatic charging
  • Protection against electrical currents
