Frequently Asked Questions
Q: What are the dimensions of the 6305 bearing?
A: The 6305 single row deep groove ball bearing has a 25 mm bore diameter, 62 mm outer diameter, and 17 mm width. These dimensions are standardized across all 6305 variants and fit manual pallet jack models specified for this bearing size.
Q: What design options are available for the 6305 bearing?
A: The 6305 is available in three configurations: open design with no shields or seals, shielded design with metal shields (Z), and sealed design with double nitrile rubber seals (2RS). Select open or shielded for applications requiring frequent re-greasing. Select sealed (2RS) for maintenance-reduced service in wet or contaminated environments.
Q: What are the equivalent part numbers for the 6305 bearing?
A: The 6305 bearing is produced by multiple manufacturers under equivalent part numbers: SKF 6305, FAG 6305, and NTN 6305. Cross-reference variants include 6305-2RS, 6305-Z, and 6305-ZZ. All meet the ISO 6305 metric bearing standard and are interchangeable.
Q: What bearing grade and precision class is the 6305?
A: The 6305 meets ABEC 1 bearing grade, which is equivalent to ISO 492 Class P0 (Normal precision). This precision class is appropriate for manual pallet jack applications where exact concentricity is not critical. Higher precision variants (ABEC 3 or ABEC 5) are available but unnecessary for this application.
Q: How does the 6305 bearing size compare to the 6304?
A: The 6305 is larger than the 6304. The 6305 has a 25 mm bore and 62 mm outer diameter versus the 6304 which has a 20 mm bore and 47-52 mm outer diameter. Do not substitute these bearings; verify that your equipment is specified for the 6305 before ordering.
