FAQ:

Question 1:  What is the difference between ZZ and 2RS seals?
Answer: ZZ bearings have metal shields on both sides, offering low friction and good protection against larger contaminants. 2RS bearings have rubber seals on both sides, providing better dust and moisture protection but with slightly higher friction.

Question 2: Does the 6308-ZZC3 bearing need lubrication?
Answer: Our 6308-ZZC3 bearings are already pre-lubricated with high-quality grease before delivery, so customers do not need to lubricate the bearings again before installation or use. The metal shields will help retain the grease inside the bearing and protect it from dust and contaminants during operation.

Question 3: When should I select C3 internal clearance instead of standard C0 clearance?
Answer:  You should select C3 internal clearance instead of standard C0/normal clearance when the bearing will operate under conditions that reduce internal clearance during use — especially higher temperature, high speed, tight fits, or heavier loads.

Question 4: Can this bearing handle axial loads?
Answer: Yes. Like other deep groove ball bearings, 6308-ZZC3 bearings can support radial loads and moderate axial loads in both directions.
