6304-2Z/C2LGJN Bearing Product Overview & Core Advantages
The 6304-2Z/C2LGJN is a metric single row deep groove ball bearing engineered for high reliability and performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while its shielded design ensures long-term operational integrity. This bearing is characterized by its compact design, making it an ideal choice for applications requiring a balance of performance and space constraints. Manufactured with precision tolerances (ABEC 1 | ISO P0) and a specified C2 radial internal clearance, it is suited for scenarios demanding consistent and predictable running accuracy.
6304-2Z/C2LGJN Bearing Model Code Explained, Specifications & Naming Convention
- 6304: Basic model number denoting a metric single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width.
- 2Z: Signifies that the bearing is shielded on both sides. These non-contact shields protect the internal components from contamination by solid particles, enhancing bearing life without significantly increasing friction.
- C2: Indicates a radial internal clearance that is smaller than the Normal (CN) group. This is selected for applications where tight fits, precise shaft alignment, or minimal runout are critical.
- LGJN: This suffix combination refers to the specific cage material and design. In this context, it denotes a cage made from Chrome Steel, offering high strength and durability suitable for a wide range of operating conditions.
6304-2Z/C2LGJN Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Built entirely from Chrome Steel (rings, balls, and cage), this bearing delivers high strength and wear resistance. Its single row deep groove geometry is optimally designed to support significant radial dynamic load ratings (3574 lbf) and radial static load ratings (1765 lbf).
Enhanced Contamination Resistance: The inclusion of 2Z shields on both sides is a key structural feature. It effectively seals the bearing against dust and debris, preserving the integrity of the internal components and the lubricant, which contributes to a maintenance-free and long service life.
Precision and Stability: Manufactured to ABEC 1 (ISO P0) tolerance class and featuring a C2 radial internal clearance, this bearing ensures smooth, low-vibration operation and precise rotational accuracy, which is vital for the consistent performance of the overall assembly.
High-Speed Capability: With a limiting speed of 14,000 rpm, the bearing is capable of operating in high-speed applications. The robust steel cage maintains ball alignment and stability even at elevated rotational speeds.
6304-2Z/C2LGJN Bearing Typical Application Areas
The 6304-2Z/C2LGJN is a versatile component found in a wide array of industrial machinery and equipment. Its combination of load capacity, speed capability, and contamination protection makes it suitable for:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Auxiliary Units (e.g., alternators, idlers)
