High-Quality Gearless double-row equal-diameter four-point contact ball type swivel bearing Manufacturer, Factories

High-Quality Gearless double-row equal-diameter four-point contact ball type swivel bearing Manufacturer, Factories

It is a pure bearing structure with smooth inner and outer rings, without any gears. A completely independent drive system is required, such as an external large gear + hydraulic motor/motor drive, or friction drive. It provides the purest and most robust load-carrying function, using all materials to construct the most complete force flow path, with no potential weak points caused by gear processing.
