2201 Bearing Product Overview & Core Advantages
The 2201 double row angular contact ball bearing is a precision bearing engineered for applications requiring high rigidity and reliable performance under combined loads. Its compact double row design enables it to simultaneously support significant radial loads and bidirectional axial loads, making it an ideal, space-saving solution for high-precision machinery. Pre-lubricated and sealed, this bearing offers long-term, maintenance-free operation, ensuring high reliability in demanding environments.
2201 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning | Benefit |
|---|---|---|
| - | Basic Designation (2201) | Defines the standard bearing dimensions: 12mm bore, 32mm OD, 14mm width. |
| Sealed | Bearing is furnished with integral contact seals on both sides. | Provides excellent protection against contaminants and retains lubricant, enabling maintenance-free operation. |
| Lubricated | Bearing is pre-filled with high-quality grease. | Ensures immediate readiness for use and long-term lubrication, contributing to a long service life. |
2201 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide superior stiffness, allowing the bearing to effectively handle combined loads (radial and axial forces from both directions) without sacrificing performance.
- Optimized for Performance: The Nylon cage contributes to smooth operation, low noise, and reduced friction, which is beneficial for high-speed applications. The standard CN radial internal clearance is suitable for a wide range of operating conditions.
- Maintenance-Free & Long-Lasting: The integral seals and factory-applied grease create a closed, lubricated system. This design eliminates the need for re-lubrication, reduces downtime, and ensures consistent performance across its specified temperature range of -30°C to 110°C.
- Precision Manufacturing: Manufactured from Chrome Steel for both rings and balls, the bearing offers high durability and wear resistance, supporting its dynamic and static load ratings.
2201 Bearing Typical Application Areas
The 2201 sealed double row angular contact ball bearing is ideally suited for a variety of compact and precision-driven applications, including:
- Small Electric Motors and Gearboxes
- Precision Spindles in Medical and Dental Equipment
- Office Automation Equipment (e.g., printers, scanners)
- Pumps and Compressors
- Precision Instruments and Measurement Devices
