A new compact version of the PRT-04 slewing ring bearing are designed for precise rotary movements under medium loads. This bearing is up to 50% flatter, 60% lighter and 20% more cost-effective than the PRT-01 model. The key to its performance and longevity is the use of dry-running, high-performance plastics in the sliding elements. The bearing also includes a reduced outer ring, which creates space in the inner diameter for directly integrating cables and drives. Systems designers can configure and order their custom slewing ring bearings using the igus online configurator.
