1207KC3 Bearing Product Overview & Core Advantages
The 1207KC3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This metric bearing features a tapered bore (1:12) for secure mounting on adapter sleeves or withdrawal sleeves, ensuring excellent concentricity. Its double row design enables it to accommodate significant combined loads—both radial and axial forces—simultaneously, making it ideal for demanding industrial environments. Manufactured from high-grade chrome steel and featuring a nylon cage, the 1207KC3 delivers reliable performance, extended service life, and is pre-lubricated for immediate installation and operation.
1207KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Basic bearing designation indicating a metric double row angular contact ball bearing with a 35mm bore diameter, 72mm outside diameter, and 17mm width. |
| K | Denotes a tapered bore with a 1:12 taper ratio, designed for mounting on adapter sleeves. |
| C3 | Indicates a greater radial internal clearance than normal (C0), suitable for applications with thermal expansion or where interference fits are used. |
1207KC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing construction provides superior rigidity and stability under heavy combined loads. This design effectively handles both radial loads and substantial axial loads in both directions, making it suitable for applications with complex force patterns.
Optimized Cage Design: The nylon cage contributes to smooth operation at the specified limiting speed of 13,000 rpm. This material offers excellent strength-to-weight ratio and operates quietly with minimal friction.
Tapered Bore Advantage: The 1:12 tapered bore ensures precise and secure mounting on shafts using adapter sleeves, providing superior running accuracy and simplified installation and disassembly procedures.
Pre-Lubricated & Ready-to-Use: The bearing comes pre-lubricated, facilitating immediate installation and initial operation without additional lubrication requirements, reducing maintenance downtime.
