The 1635-2Z RICH is a precision-manufactured single row deep groove ball bearing with inch dimensions (3/4" x 1-3/4" x 1/2"). This bearing is designed to handle both radial and axial loads at high rotational speeds. The "2Z" (or ZZ) designation signifies that the bearing is equipped with non-contact metal shields on both sides. These shields protect the internal ball set and raceways from larger particles of debris while ensuring that the factory-applied grease remains inside the bearing. Because the shields do not make contact with the inner ring, they generate significantly less friction than rubber seals, making this bearing ideal for high-speed applications where heat generation must be kept to a minimum. Featuring a robust steel cage for consistent ball spacing and a standard CN clearance, the 1635-2Z is a reliable component for power tools, small machinery, and automotive aftermarket applications.
Transparency Note: This product is manufactured under the RICH brand. The code 1635-2Z is used for identification and interchange purposes and does not imply affiliation with other manufacturers.
