1210KJC3 Bearing Product Overview & Core Advantages
The 1210KJC3 is a double row angular contact ball bearing designed for applications requiring superior rigidity and the ability to handle combined loads. Featuring a metric design with a tapered bore (1:12), this precision bearing offers high radial and axial load capacity in a compact cross-section. Its open construction and optimized internal geometry make it suitable for demanding, high-reliability industrial environments where precise shaft location is critical.
1210KJC3 Bearing Model Code Explained, Specifications & Naming Convention
- 1210: Standard bore diameter code (50 mm) and series designation.
- K: Indicates a tapered bore with a 1:12 ratio, facilitating precise mounting and dismounting on adapter sleeves or withdrawal sleeves.
- J: Denotes an optimized internal design and steel cage construction.
- C3: Specifies a greater than normal radial internal clearance, making it suitable for applications with higher operational temperatures or where interference fits are used.
1210KJC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball construction provides significantly higher rigidity compared to single row bearings, enabling stable support for shafts under substantial combined radial and axial loads.
Precision Tapered Bore: The K-designation tapered bore ensures a secure, interference-free fit when mounted with appropriate sleeves, enhancing running accuracy and simplifying maintenance.
Optimized for Demanding Conditions: The C3 radial internal clearance accommodates thermal expansion and interference fits, preventing pre-loading and ensuring smooth operation. The robust steel cage provides high strength and durability for stable performance.
Material Integrity: Manufactured from high-grade chrome steel for both rings and balls, the bearing ensures excellent wear resistance and a long operational lifespan under demanding conditions.
