6309 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and single row design are optimized to handle significant radial loads (dynamic: 11915 lbf, static: 7194 lbf), ensuring durability and long service life.
- Precision Engineering: Built to ABEC-1 tolerance standards, this bearing provides reliable running accuracy, minimizing vibration and noise for smooth operation.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 6,700 rpm, making it suitable for applications requiring rapid rotation.
- Superior Material Construction: Components made from chrome steel (rings and balls) offer excellent hardness and wear resistance, while the stainless steel cage provides strength and corrosion resistance.
6309 Bearing Typical Application Areas
The 6309 bearing is a versatile component found in numerous sectors, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring a reliable, standard-duty ball bearing.
