1201S Bearing Product Overview & Core Advantages
The 1201S is a metric double row angular contact ball bearing designed for applications requiring high precision and reliability. This bearing excels at simultaneously handling combined radial and axial loads from both directions. Its compact design, featuring a 12 mm bore and 32 mm outside diameter, makes it ideal for space-constrained assemblies. Manufactured with chrome steel rings and balls, and a nylon cage, it offers excellent performance for high-speed operation up to 32,000 rpm, ensuring robust performance in demanding environments.
1201S Bearing Model Code Explained, Specifications & Naming Convention
The model number 1201S can be broken down to understand its technical specifications:
- 12: Indicates a 12 mm bore diameter.
- 01: Refers to the bearing series, defining its cross-sectional dimensions.
- S: Signifies that the bearing is supplied with a CN radial internal clearance group, which is the standard for general applications.
1201S Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to support significant combined loads (radial and bidirectional axial loads), with a dynamic load rating of 1404 lbf and a static load rating of 322 lbf.
- High-Speed Performance: The lightweight nylon cage is instrumental in achieving a high limiting speed of 32,000 rpm, reducing centrifugal forces and friction for smooth, efficient operation.
- Precision & Reliability: Manufactured from high-grade chrome steel with tight dimensional tolerances, this bearing ensures consistent performance and long service life. The standard CN radial internal clearance is suitable for a wide range of operating conditions.
- Immediate Operation: The bearing comes pre-lubricated, allowing for immediate installation and use without the need for initial greasing.
1201S Bearing Typical Application Areas
The 1201S double row angular contact ball bearing is ideally suited for:
- Electric Motors and Small Spindles requiring high-speed and precision.
- Precision Instruments and Optical Devices where compact size and reliability are critical.
- Office Automation Equipment such as printers and scanners.
- Medical Devices demanding quiet operation and high rotational accuracy.
- Various Industrial Machinery components where robust performance under combined loads is essential.
