They are used to accommodate radial and axial loads in both directions(Mainly bear radial load, but also can bear a certain amount of axial load). It is constructed using chrome steel material, and its sealing type features a metal cover. With high-speed capabilities, low friction, and minimal noise levels, this bearing ensures optimal performance. This type of bearing is used in industries such as precision instruments, low-noise motors and general machinery, and is the most widely used type of bearing in the machinery industry. Selecting Guide: Open Type (No Designation Suffix) - Suitable for high-speed and even very high-speed operation. Shielded (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris. Sealed (Designation Suffix RS/2RS) - Made of sheet steel reinforced nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than metal shield bearings.
