E2.629-2Z/C3 Bearing Product Overview & Core Advantages
The E2.629-2Z/C3 is a metric single row deep groove ball bearing engineered for high reliability in demanding applications. Its core advantages stem from its shielded design (2Z), which provides effective protection against contaminant ingress, and its specified C3 radial internal clearance, making it suitable for applications with elevated operational temperatures or where interference fits are used. This bearing is designed to primarily handle radial loads and offers a high limiting speed, ensuring stable performance. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent quality and is compliant with RoHS and REACH directives.
Model Code Breakdown
| Suffix / Prefix | Technical Meaning |
|---|---|
| E2.629 | Basic bearing designation, indicating a specific size series and dimensions (9mm bore, 26mm OD, 8mm width). |
| 2Z | Signifies that the bearing is shielded on both sides. This provides superior protection against dust and other particulates, helping to maintain performance and extend service life without contact, minimizing friction. |
| /C3 | Indicates that the bearing has a greater than normal radial internal clearance (Group C3). This is advantageous in applications involving thermal expansion, heavy loads, or where shaft and housing fits result in a reduction of internal clearance. |
E2.629-2Z/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built entirely from chrome steel for the rings, balls, and cage, this bearing offers excellent durability and a high radial dynamic load rating of 1068 lbf, ensuring reliable operation under significant stress.
- Optimized for Speed: The design and materials contribute to a high limiting speed of 30,000 rpm, making it suitable for high-speed applications such as small motors and spindles.
- Shielded & Pre-Lubricated for Protection: The non-contact 2Z shields effectively seal the bearing from contaminants while minimizing friction. The bearing is supplied without lubrication ("None"), allowing for application-specific greasing or use in environments where standard lubricants are not suitable.
- Wide Operating Temperature Range: With a specified temperature range from -30°C to 120°C, this bearing is versatile for use in various environmental conditions.
E2.629-2Z/C3 Bearing Typical Application Areas
The E2.629-2Z/C3 is ideally suited for a wide range of compact and high-speed machinery, including:
- Small Electric Motors and Generators
- Precision Instruments and Medical Devices
- Office Automation Equipment (e.g., printers, scanners)
- Cooling Fans and Blowers
- Light-duty Gearboxes and Power Transmission Systems
