Frequently Asked Questions
Q: What is the difference between the 6000, 6001, 6002, 6003, 6004, and 6005 bearing series?
A: Each model number in the 6000 series refers to a specific set of dimensions — primarily differing in inner bore diameter and outer diameter. The 6000 series (10×26×8mm) is one of the smallest, while the 6005 is progressively larger. All share the same deep groove design and are suitable for both radial and axial loads at high speeds.
Q: What does "DDU" mean on these deep groove ball bearings?
A: "DDU" indicates that the bearing is sealed on both sides with a rubber contact seal. This design effectively keeps internal grease lubrication in place while blocking dust, dirt, and moisture from entering, making the bearing ideal for environments where contamination is a concern.
Q: What does the C3 clearance rating mean?
A: C3 clearance refers to a greater-than-normal internal radial clearance between the balls and races. This is recommended for applications involving higher operating temperatures or higher rotational speeds, as it allows for thermal expansion without causing excessive preload or bearing seizure.
Q: Are these bearings pre-lubricated?
A: Yes. As double-sealed (DDU) bearings, they come pre-packed with grease and are maintenance-free under normal operating conditions. The rubber seals keep the lubricant securely inside throughout the bearing's service life.
Q: Can these bearings be used in high-speed applications?
A: Absolutely. The JARBLUE 6000–6005 DDU C3 bearings are specifically designed for high-speed operation. The precision bearing steel construction, optimized ball geometry, and C3 clearance all contribute to smooth, efficient performance at elevated rotational speeds.
