Frequently Asked Questions
Q: What are the exact dimensions and load ratings for the 6205ZZ bearing?
A: The 6205ZZ has a 25 mm bore, 52 mm outside diameter, and 15 mm width. Dynamic radial load capacity is 14,000 N (3,148 lbf). Static load capacity is 7,850 N (1,764 lbf). Maximum rotational speed under grease lubrication is 13,000 RPM. Precision grade is ISO Class 0.
Q: Which manual pallet jack brands and models use the 6205ZZ bearing?
A: The 6205ZZ fits manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other standard material handling equipment manufacturers. This bearing is commonly used in load wheel assemblies and general industrial machinery. Verify your equipment bore diameter matches 25 mm before ordering.
Q: Is the 6205ZZ interchangeable with NTN and JET bearing numbers?
A: Yes. The 6205ZZ is OEM interchangeable with NTN 6205ZZ and JET JT9-BB-6205ZZ. Cross-reference the part number on your equipment documentation to confirm compatibility before installation.
Q: What material and shielding does the 6205ZZ use?
A: The 6205ZZ is fabricated from high carbon chrome steel with a pressed steel cage. The bearing features double steel shields (ZZ) that protect against contamination. This design provides durability in industrial and cold storage environments common to material handling equipment.
Q: How long will the 6205ZZ bearing last in normal operation?
A: Bearing lifespan depends on load, speed, lubrication, and environment. Pre-lubricated sealed bearings are maintenance-free during normal use. Monitor for noise or resistance increases, which indicate wear. Replace if performance degrades. High carbon chrome steel construction ensures long life under rated dynamic load conditions.
