PRT-04 slewing ring bearing with internal gearing

For even more compact drive solutions

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.
