Frequently Asked Questions
Q: What are the exact dimensions of the BS 6305 ZZ bearing?
A: The BS 6305 ZZ has an outer diameter of 2.441 inches (62 mm), an inner diameter of 0.984 inches (25 mm), and a width of 0.669 inches (17 mm). Verify these dimensions match your equipment bore and housing before ordering, as bearing fit tolerance is critical for proper operation.
Q: What does the ZZ designation mean for this bearing?
A: The ZZ designation indicates the bearing has double steel shields on both sides. These shields are sealed bearing components that retain grease and exclude contamination without contact with the rolling elements. This configuration is suitable for general industrial material handling equipment operating in relatively dry conditions.
Q: What equipment types use the BS 6305 ZZ bearing?
A: The BS 6305 ZZ is a deep groove ball bearing compatible with various manual and electric pallet jacks, load wheels, and casters from brands including Crown, Toyota, Raymond, Yale, and Hyster. Confirm compatibility with your specific equipment model and serial number before ordering.
Q: What is the typical lifespan of this bearing?
A: Bearing lifespan depends on load, speed, lubrication, and operating conditions. For material handling equipment in typical warehouse environments, a well-maintained BS 6305 ZZ usually performs reliably for 1 to 3 years. Factors like wet floors, cold storage, or continuous heavy use can reduce this timeframe.
Q: Is the BS 6305 ZZ equivalent to other bearing part numbers?
A: The BS 6305 ZZ is equivalent to standard deep groove ball bearings from manufacturers such as NSK, SKF, Koyo, FAG, NTN, and SNR using the designation 6305ZZ. Always verify the complete part number, seal configuration, and precision grade before substituting, as variations exist across suppliers.
