1305 C/3 Bearing Product Overview & Core Advantages
The 1305 C/3 is a metric double row angular contact ball bearing engineered for high-performance applications. This precision bearing is designed to accommodate significant combined loads, simultaneously handling radial forces and axial loads in both directions. Its compact bearing dimensions (25mm bore, 62mm OD, 17mm width) and robust double-row construction provide exceptional high rigidity and operational stability, making it an ideal choice for machinery demanding high reliability and precision.
1305 C/3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 1305 C/3 provides key technical specifications:
- 1305: Basic bearing series, indicating a 25mm bore and 62mm outside diameter.
- C: Denotes a specific internal design with a 15° contact angle, optimized for handling axial loads.
- 3: Indicates a C3 radial internal clearance, which is greater than standard (CN) clearance, suitable for applications with thermal expansion or where interference fits are used.
1305 C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and 15° contact angle create a rigid structure capable of supporting substantial combined radial and axial loads from both directions.
- Optimized for Performance: The Nylon cage ensures smooth operation at high speeds with reduced friction and is suitable for the specified limiting speed. The open seal type allows for optimal lubrication flow and heat dissipation.
- Precision & Reliability: Manufactured from Chrome Steel for both rings and balls, this bearing offers high durability and wear resistance. It comes pre-lubricated and is ready for installation, operating effectively within a temperature range of -30°C to 110°C.
1305 C/3 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- General machinery requiring robust support for combined loads.
