Trust ball bearings are produced in the form of one-way or double-directional support ball bearings. They are designed in such a way that they are suitable only for axial loads and must not be subjected to any radial load.

JSC Hidrobal supplies trust ball bearings that meet special application requirements. The trust bearing is a certain type of rotary bearing. Like other bearings, they constantly rotate between parts, but they are designed to maintain an axial load. Trust bearings are of several types: trust ball bearings, consisting of bearing balls supported in the ring, can be used in small devices with a small axial load. Cylindrical trusting roller bearings consist of small cylindrical rollers arranged flatly, and their axes are directed to the bearing axis. They provide very good lifting capacity and are cheap, but tend to wear due to differences in radial speed and friction, which are larger than when using ball bearings.
