Frequently Asked Questions
Q: What are the dimensions and specifications of the 6205Z bearing?
A: The 6205Z is a standard single-row deep groove ball bearing with a single metal shield (Z designation), dimensions of 25 mm bore, 52 mm outside diameter, and 15 mm width. It is rated for radial loads up to 15.5 kN dynamic and 7.85 kN static load capacity.
Q: What are the cross-reference part numbers for the 6205Z?
A: Cross-reference part numbers include BB-6205Z (JET), 6205-Z (SKF, NTN-SNR), M0901-6205Z-Z (Toyota), 6205, and 6205-2RS (sealed variants). Verify bore, outside diameter, and width dimensions before cross-referencing, as slight manufacturing variations may affect fit.
Q: What is the difference between 6205Z and sealed variants like 6205-2RS?
A: The 6205Z features a single metal shield on one side, providing some protection from debris while allowing easier access for lubrication and lower friction. Sealed variants like 6205-2RS provide dual rubber seals on both sides, offering better contamination protection but higher friction and reduced speeds.
Q: Is the 6205Z suitable for wet or outdoor storage environments?
A: The single metal shield on the 6205Z provides limited protection against water and moisture. For applications in wet floors or outdoor material handling environments, sealed variants with rubber seals (6205-2RS, 6205RS, or 6205LLB) are better suited to prevent corrosion and extend bearing lifespan.
Q: What load capacity does the 6205Z support in manual pallet jack applications?
A: The 6205Z supports radial loads up to 15.5 kN dynamic and 7.85 kN static load capacity. These ratings are typical for manual pallet jack wheel and pump assemblies. Ensure that your equipment load does not exceed these specifications during operation.
Q: What maintenance does the 6205Z require compared to sealed bearings?
A: The 6205Z is open on one side (Z shield provides partial protection only), requiring more frequent inspection and lubrication than sealed variants. Monitor for contamination ingress and grease degradation. In dusty or wet environments, sealed bearings require less maintenance and provide longer service life.
