Frequently Asked Questions
Q: What are the dimensions of the CA 902051 bearing?
A: The CA 902051 measures 20 mm inner diameter, 47 mm outer diameter, and 14 mm thickness. This size is standard for manual pallet jack wheel assemblies and fits most common wheel hub designs.
Q: What load ratings does the CA 902051 have?
A: The CA 902051 has a static load rating of 1980 lbs and a dynamic load rating of 3020 lbs. These ratings are suitable for standard manual pallet jack capacity applications up to 5000 lbs.
Q: What materials are used in the CA 902051?
A: The CA 902051 is manufactured from ASTM 52100 high carbon chromium steel with a pressed steel cage and synthetic NBR rubber seals. This material combination provides corrosion resistance and durability in warehouse environments.
Q: Is the CA 902051 sealed, and what is the seal type?
A: Yes. The CA 902051 features two synthetic NBR rubber seals that protect the bearing races and rolling elements from dust, moisture, and contaminants common in industrial material handling applications.
Q: Does the CA 902051 require lubrication, and how often?
A: The CA 902051 is factory-lubricated at manufacture. The sealed design minimizes relubrication needs. Under normal manual pallet jack operation, maintenance intervals are extended compared to open bearings.
Q: What manufacturing standards does the CA 902051 meet?
A: The CA 902051 is manufactured to ISO 492 Class P0 tolerance specifications, ensuring precision fit and long bearing life in wheel hub applications across manual pallet jack equipment.
