The 5201.ZZ RICH is a high-performance double row angular-contact ball bearing designed to manage heavy radial loads and axial loads in both directions simultaneously. Its internal configuration corresponds to two single row angular-contact bearings arranged back-to-back, but in a more compact, integrated design. This structure provides high tilting stiffness, making it particularly effective for applications where rigid shaft guidance is required. The "ZZ" designation indicates that the bearing is equipped with non-contact metal shields on both sides, which protect the internal rolling elements from large particles of debris while maintaining the factory-applied grease. Because these shields do not contact the inner ring, the bearing operates with very low frictional torque, allowing for higher rotational speeds compared to rubber-sealed versions. Featuring a lightweight polyamide cage for quiet operation and a 12 mm bore, the 5201.ZZ is a versatile component for automotive pumps, air conditioning compressors, and industrial power tools.
Key Performance Advantages:
Bi-directional Axial Support: Capable of handling thrust loads from both sides, providing superior stability over single row designs.
Low Friction High Speed: Metal shields (ZZ) ensure minimal heat generation, making this bearing ideal for high-RPM machinery.
Rigid Guidance: The angular contact design offers a high degree of stiffness, resisting shaft tilting and ensuring precise positioning.
Polyamide Cage: Provides excellent sliding properties and dampens vibration for smoother, quieter performance.
Transparency Note: This product is manufactured under the RICH brand. The code 5201.ZZ is used for identification and interchange purposes and does not imply affiliation with other manufacturers.
