RNU 2212 ECP is a NU type single row cylindrical rolling bearing without an inner ring, consisting of an outer ring component with rollers and cages, typically used in applications where the shaft surface has hardened and ground raceways. When there is no inner ring, a larger shaft diameter can be used to improve the strength and stiffness of the shaft. The bearing allows bidirectional axial displacement, which is only limited by the width of the raceway on the shaft. It has the following characteristics:
1. Structure: The NU type bearing consists of a set of cylindrical rollers and two shoulderless inner and outer rings.
2. Load bearing capacity: NU type bearings have high axial load bearing capacity and can also withstand bidirectional axial displacement to a limited extent.
3. Application scope: Suitable for applications that require high axial stiffness and small space limitations, such as mechanical transmission systems with high rotational speeds, motors, conveyor belts, and other equipment.
4. Installation and adjustment: During installation, it is necessary to ensure good axial positioning and pay attention to correct lubrication.
5. Detachable structure: NU type bearings usually have a detachable design for easy installation, maintenance, and replacement.
