The combination of a high load capacity four-point contact ball bearing and INA spherical plain bearings is a system solution that has proven successful in practice for many years, for example in articulation/swivel joints or fifth wheel hitches, which is a rugged and compact system for torsional and steering motion. The four-point contact ball bearing has a high load rating, is particularly rigid and is easy to mount. With its clearance-free preloaded raceway system, this bearing is more than a match for the high requirements in these types of applications.
The maintenance-free bearings in our system solutions are designed for high loads. Regardless of the design, be it radial, axial or angular contact spherical plain bearings, the performance of our “maintenance-free units” is always unbeatable.
