1202K Bearing Product Overview & Core Advantages
The 1202K is a metric double row angular contact ball bearing engineered for applications demanding high rigidity and reliable performance under combined loads. Its unique tapered bore (1:12) design facilitates precise mounting and secure shaft fixation. This bearing excels in handling significant radial loads while its double-row construction contributes to its compact dimensions and robust performance in high-precision environments requiring dependable operation.
1202K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1202 | Basic bearing designation, indicating a double row angular contact ball bearing with a 15mm bore and 35mm outside diameter. |
| K | Denotes a tapered bore with a 1:12 ratio, allowing for interference fit on adapter sleeves or withdrawal sleeves for precise axial positioning. |
| Open (Seal Type) | The bearing is supplied without seals or shields, optimized for applications where external sealing is provided or for re-lubrication access. |
| CN (Radial Clearance) | Specifies the standard radial internal clearance group, suitable for most common operating conditions. |
1202K Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing design provides superior stiffness, effectively supporting combined loads (radial and axial). This makes it ideal for applications where shaft deflection must be minimized.
Precision Tapered Bore: The K-suffix tapered bore (1:12) ensures a secure, interference fit on a tapered shaft or adapter sleeve. This design enhances running accuracy, simplifies mounting/dismounting, and is critical for applications requiring high positional precision.
Optimized for Performance: Featuring a lightweight nylon cage, the bearing is capable of achieving a limiting speed of 28,000 rpm. The open design, when used with appropriate lubrication, supports efficient high-speed operation.
Material & Compliance: Constructed from high-grade chrome steel for both rings and balls, the bearing ensures durability and a long service life. It is pre-lubricated and compliant with ROHS and REACH environmental standards.
