Product Description
6306 DDU LLU 2RS ZZ C3 Deep groove Ball Bearing 6300 6301 6302 6304 6305 ball bearings

The 6306 DDU deep groove ball bearing (standard dimensions: 30mm ID × 72mm OD × 19mm Width) is a versatile general-purpose bearing designed for diverse industrial transmission scenarios. Equipped with double-sided contact rubber seals (DDU), it provides excellent dustproof and waterproof performance, effectively isolating external contaminants while retaining lubricating grease. Crafted from premium GCr15 bearing steel, it undergoes precision heat treatment and raceway superfinishing, delivering high radial load capacity, low friction, and stable long-term operation. Its deep groove structure enables it to bear moderate axial loads in both directions, making it suitable for a wide range of general mechanical equipment. Customizable lubrication types and seal structures are supported to meet personalized working condition requirements.

FAQ
  1. Q: What is the function of the DDU seal in 6306 DDU bearings? A: The DDU double-sided contact rubber seal isolates external dust, moisture, and contaminants, while preventing lubricating grease leakage, suitable for relatively harsh general industrial environments.
  2. Q: Can 6306 DDU bearings bear axial loads? A: Yes, its deep groove structure enables it to bear moderate bidirectional axial loads (in addition to main radial loads), adapting to most general transmission scenarios.
  3. Q: What is the recommended operating speed for 6306 DDU bearings? A: Under grease lubrication, the limit speed is about 6000 r/min; under oil lubrication, it can reach up to 8000 r/min (specific values depend on actual working conditions).
