Frequently Asked Questions
Q: What are the HV6306ZZ bearing dimensions and specifications?
A: The HV6306ZZ has a 30 mm bore, 72 mm outer diameter, and 19 mm width. It is a double-shielded deep groove ball bearing manufactured from SAE 52100 bearing steel with SAE 52100 high-carbon chromium steel balls. Metal shields on both sides provide particulate protection.
Q: What material is used in the HV6306ZZ bearing?
A: The race is constructed from through-hardened SAE 52100 bearing steel, and the balls are SAE 52100 high-carbon chromium steel. This material composition provides hardness, durability, and corrosion resistance for manual pallet jack load wheel applications.
Q: What is the purpose of the metal shields on the HV6306ZZ?
A: The double metal shields protect the bearing interior from particulates, dirt, and moisture exposure in warehouse and loading dock environments. This design extends bearing life and maintains consistent rolling resistance.
Q: Is the HV6306ZZ suitable for manual pallet jack replacement?
A: Yes, the HV6306ZZ is engineered as a direct replacement bearing for manual pallet jack load wheel applications. Confirm that your equipment hub matches the 30 mm bore and 72 mm outer diameter specification before installation.
Q: Does the HV6306ZZ come pre-lubricated?
A: The HV6306ZZ is typically supplied with factory lubrication. Check the product packaging or specification sheet to confirm lubrication status. Do not assume relubrication is necessary without inspection of the bearing condition.
