Bearing (1 metal shield)
Frequently Asked Questions
Q: What is the Z designation and how does it differ from other 6204 variants?
A: The Z designation indicates a single metal shield on one side of the bearing. This provides light contamination protection while maintaining lower friction compared to dual-shielded bearings. The open side allows grease migration, making it suitable for general industrial and material handling equipment.
Q: What are the dimensions and load rating of the BS 6204 Z?
A: The BS 6204 Z has a 20 mm bore, 47 mm outside diameter, and 14 mm width. It is rated for dynamic radial loads up to 2220 lbs and is suitable for pallet jacks, load wheels, and other material handling equipment requiring moderate radial load capacity.
Q: Is the BS 6204 Z pre-lubricated and what is its service temperature range?
A: Yes, the BS 6204 Z is factory pre-greased and ready for installation. Standard steel variants operate from -10 degrees Celsius to 120 degrees Celsius. For cold storage applications, specify low-temperature grease to prevent grease hardening and bearing starvation.
Q: Can the BS 6204 Z be used interchangeably with ZZ (double-shielded) bearings?
A: Physically, yes, both have identical outer dimensions. However, the single metal shield on the Z variant provides less contamination protection than the ZZ double-shield design. Choose Z for general factory environments and ZZ for wet, dusty, or washdown areas.
Q: What cross-reference part numbers are equivalent to the BS 6204 Z?
A: The BS 6204 Z is equivalent to standard industry 6204-Z bearings. Cross-references include SKF 6204-Z, KOYO 6204-Z, FAG 6204-Z, and NSK 6204-Z. Verify exact part specifications before ordering to ensure compatibility with your equipment.
