Frequently Asked Questions
Q: What is the difference between 6305-ZZ and 6305-Z?
A: The 6305-ZZ features double metal shields on both sides, providing superior protection against contamination compared to the 6305-Z which has a single shield. Both share identical dimensions: 25 mm bore, 62 mm outer diameter, and 17 mm width.
Q: What are the full specifications of the 6305-ZZ bearing?
A: The 6305-ZZ is a double-row deep groove ball bearing with a 25 mm bore, 62 mm outer diameter, 17 mm width, manufactured from bearing-grade chrome steel. It meets ABEC 3 precision standards and conforms to ISO 6300 series specifications.
Q: What materials are used in the 6305-ZZ bearing assembly?
A: The bearing is constructed from chrome steel (SAE 52100 equivalent) with a pressed-steel cage and metal shields on both sides. The double-shield design provides enhanced protection against moisture and debris in damp or outdoor environments.
Q: Which manual pallet jack brands use the 6305-ZZ bearing?
A: The 6305-ZZ is used in manual pallet jacks and industrial machinery from Crown, Toyota, Raymond, Yale, and similar manufacturers. Always verify equipment compatibility by checking your pallet jack manual or existing bearing part numbers.
Q: What cross-references are available for 6305-ZZ?
A: The 6305-ZZ is equivalent to part numbers 6305Z, 6305 2Z, 6305ZZ, MZLZ-005-021, and 6305-2Z. These are direct equivalents and fully interchangeable for manual pallet jack load wheel applications.
Q: Is 6305-ZZ pre-lubricated and maintenance-ready?
A: Yes, the bearing arrives pre-lubricated with grease and requires no additional lubrication prior to use. The double metal shields retain the grease longer than open or single-shield designs, extending bearing lifespan in typical material handling applications.
