Frequently Asked Questions
Q: What is the BS 6307 ZZ bearing and what are its key specifications?
A: The BS 6307 ZZ is a deep groove ball bearing with a 35 mm bore diameter, 80 mm outside diameter, and 21 mm width. It features double steel shields (ZZ configuration), high-carbon chromium steel rolling elements, and Class 0 ISO/JIS precision grade. Radial load capacity is 41.7 kN with a maximum rotation speed of 8,500 RPM.
Q: What are the cross-reference and equivalent part numbers?
A: The BS 6307 ZZ is equivalent to NSK 6307ZZ, Koyo 6307ZZ, SNR 6307ZZ, FAG 6307ZZ, and NTN 6307ZZ. Additional references include 6307-ZZ and 6307ZZC3. Always confirm precision grade, material, and load rating match your original bearing before substituting with an equivalent.
Q: Is the BS 6307 ZZ suitable for manual pallet jack wheel assemblies?
A: Yes, the BS 6307 ZZ is specifically designed for use in manual pallet jack wheel assemblies and electric pallet jack caster units. It is compatible with equipment from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and Linde. Verify bore size and housing fit for your specific equipment model.
Q: What material and precision grade is this bearing manufactured to?
A: The BS 6307 ZZ is manufactured from high-carbon chromium steel with rolling elements meeting Class 0 (ISO/JIS) precision specifications. This material provides the durability and load-bearing capability required for material handling equipment, ensuring smooth operation and minimal vibration.
Q: What are the operating conditions and environmental limits?
A: The BS 6307 ZZ with double steel shields performs reliably in dry to moderately moist warehouse environments at room temperature. Maximum speed is 8,500 RPM with 41.7 kN radial load capacity. For wet floor or cold storage environments, consider the 2RS seal version for superior moisture protection.
Q: How do I verify this bearing is compatible with my pallet jack model?
A: Verify compatibility by checking your equipment's parts manual or parts diagram for bearing specifications including bore diameter (35 mm) and width (21 mm). Confirm the housing type and any load requirements match the bearing's 41.7 kN capacity. Contact your equipment manufacturer or parts distributor if specifications are unclear.
