Frequently Asked Questions
Q: What is the BS 6006 Z bearing and what are its key specifications?
A: The BS 6006 Z is a single-row deep groove ball bearing with a metal shield on one side. It is part of the 6006 bearing family with a 30 mm bore and 55 mm outside diameter. This bearing is commonly used in manual pallet jack wheel assemblies and other light industrial material handling equipment.
Q: How does the BS 6006 Z differ from the BS 6006 ZZ model?
A: The BS 6006 Z has a single metal shield on one side, while the BS 6006 ZZ has metal shields on both sides. The single-shield Z variant provides less dust protection but may be lighter and less restrictive on RPM limits. Choose the Z if your equipment calls for single-side protection, or upgrade to ZZ for enclosed environments or dirty conditions.
Q: What materials are used in the BS 6006 Z bearing construction?
A: The BS 6006 Z uses chrome steel (SAE 52100 equivalent) for the bearing races and balls, providing hardness and durability for repeated loading. The single metal shield is typically made from low-carbon steel. The pressed steel cage maintains ball spacing and allows free rolling.
Q: What is the difference between open bearing (BS 6006) and shielded bearing (BS 6006 Z)?
A: An open bearing (no designation) has no seals or shields, allowing access for re-lubrication but offering no dust protection. The BS 6006 Z adds a single metal shield that reduces contamination and provides partial protection while still allowing relatively high RPM operation. For sealed or shielded models with maximum protection, consider BS 6006 ZZ or BS 6006 2RS.
Q: Is the BS 6006 Z compatible with standard equipment that uses 30 mm bore bearings?
A: The BS 6006 Z with its 30 mm bore and 55 mm outside diameter is compatible with pallet jack models and industrial equipment designed for standard 6006-size bearings. Verify dimensions match your specific equipment before ordering. This bearing works with Crown, Toyota, Raymond, and other OEM brands using 6006-size specifications.
