1310JC3 Bearing Product Overview & Core Advantages
The 1310JC3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high load capacity and robust performance. This precision bearing features an open design with a C3 radial internal clearance, making it ideally suited for applications where thermal expansion is a factor. Its double row construction provides superior rigidity and enables it to accommodate combined loads—significant radial forces along with axial loads in both directions. Manufactured from high-grade chrome steel, it offers excellent durability and reliable operation within a wide temperature range.
1310JC3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 1310JC3 provides specific technical information:
- 1310: Basic designation indicating a metric double row angular contact ball bearing with a 50mm bore diameter.
- J: Denotes a steel cage design, providing high strength and suitability for a wide range of operating conditions.
- C3: Specifies a greater than normal radial internal clearance. This is critical for applications involving high operational temperatures or where fits cause a reduction in clearance, ensuring optimal performance and longevity.
1310JC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design significantly increases rigidity compared to single row bearings. This structure enables it to support substantial radial dynamic load ratings (9810 lbf) and static load ratings (3150 lbf), effectively handling combined loads.
- Optimized for Thermal Expansion: The specified C3 clearance allows for thermal expansion of the shaft and housing during operation, preventing premature failure due to excessive preload, which is essential for maintaining performance in variable temperature environments.
- Robust Construction: Components made from chrome steel (rings, balls) and a steel cage ensure high mechanical strength, wear resistance, and a long service life under demanding conditions.
- Broad Operating Range: With a limiting speed of 8000 rpm and a temperature range from -30°C to 110°C, this bearing is versatile for numerous high-speed and general industrial applications.
1310JC3 Bearing Typical Application Areas
This bearing is engineered for applications that demand high load capacity and reliability. Common uses include:
- Industrial Gearboxes
- Electric Motors
- Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
