Frequently Asked Questions
Q: What does the 6307ZZ designation mean?
A: The 6307ZZ is a sealed deep groove ball bearing with double metal shields (ZZ). The sealed design protects internal components from contamination. The 6307 prefix indicates a metric bearing size with standard bore and load ratings used in material handling equipment.
Q: What equipment types is the 6307ZZ bearing designed for?
A: This bearing is used in electric and manual pallet jacks, forklifts, and material handling carts from manufacturers like Crown, Raymond, Toyota, Hyster, and Yale. Verify your equipment model number and bearing mounting location before ordering to confirm compatibility.
Q: How does the 6307ZZ compare to open bearing designs?
A: The double metal shields (ZZ) protect the bearing races and balls from moisture and debris, extending service life in wet or dusty warehouse environments. The sealed design reduces maintenance compared to open bearings but cannot be relubricated.
Q: Is there a different part number if I need a bearing without shields?
A: Yes, open bearing versions exist but are not recommended for material handling equipment. The sealed ZZ design is standard for pallet jacks and forklifts. Contact us if you need alternative bearing configurations for a specific application.
