Frequently Asked Questions
Q: What are the dimensions of the 6204Z bearing?
A: The 6204Z has a 20 mm bore diameter, 47 mm outer diameter, and 14 mm width. It is a single shielded deep groove ball bearing suitable for manual pallet jack wheel and undercarriage applications.
Q: Which manual pallet jack models are compatible with the 6204Z?
A: The 6204Z is compatible with WP3000 and WP3035-45 manual pallet jacks. Cross-reference the bearing designation on your equipment or consult the parts diagram to confirm compatibility before ordering.
Q: What cross-reference part numbers exist for the 6204Z?
A: The 6204Z has the following cross-references: SKF 6204-Z, NTN 6204Z, NSK 6204Z, FAG 6204Z, and Nachi 6204Z. All are equivalent single shield deep groove ball bearings with identical dimensions and are interchangeable.
Q: Does the 6204Z replace the double-shielded 6204ZZ?
A: The 6204Z (single shield) can replace the 6204ZZ (double shield) only if your equipment was originally designed for a single shield bearing. The 6204Z provides lower friction than double-shielded designs but offers less contamination protection. Verify your original bearing designation before substituting.
Q: What material is the 6204Z constructed from?
A: The 6204Z features high carbon chromium steel construction with a pressed steel cage. This combination provides the hardness and durability needed for manual pallet jack wheel assemblies and undercarriage support.
Q: What is the dynamic load rating for the 6204Z bearing?
A: The 6204Z is rated for industry-standard dynamic load capacity typical of single-shielded deep groove ball bearings in this size class. This capacity is adequate for manual pallet jack wheel support under standard material handling loads.
