627-2RZTN9/C3GMG Bearing Product Overview & Core Advantages
The 627-2RZTN9/C3GMG is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric precision bearing features integrated seals and is optimized to handle significant radial loads while offering smooth operation. Its compact design, with a 7mm bore and 22mm outside diameter, makes it ideal for applications where space is limited but performance cannot be compromised. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent quality and is pre-lubricated for immediate use, providing a robust solution for high-speed machinery up to 30,000 rpm.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 627 | Basic bearing series, indicating a single row deep groove design with specific dimensions (7mm bore, 22mm OD, 7mm width). |
| -2RZ | Sealing type: Features non-contact seals on both sides. The "RZ" suffix denotes low-friction rubber seals with steel reinforcements, offering effective protection against contaminants with minimal impact on speed capability. |
| TN9 | Cage type: Constructed from glass fiber reinforced polyamide (Nylon). This lightweight cage contributes to lower inertia, reduced friction, and is suitable for high-speed operation and acceleration. |
| /C3 | Internal clearance: Specifies a greater than normal radial internal clearance (Group C3). This is beneficial for applications with expected thermal expansion, such as in electric motors, or where interference fits are used. |
| GMG | Lubrication: Indicates the bearing is pre-greased with a specific, high-quality lithium soap complex grease. This grease provides excellent performance across the specified temperature range (-30°C to +120°C). |
627-2RZTN9/C3GMG Bearing Structural Features & Performance Benefits
- Optimized Deep Groove Raceway: The deep, continuous raceways on both rings are precision-ground to facilitate smooth rolling motion and efficient radial load support.
- Sealed for Protection and Long Life: The non-contact 2RZ seals effectively shield the internal components from dust, moisture, and other contaminants while maintaining low running torque, which is critical for achieving the high limiting speed of 30,000 rpm.
- High-Speed Nylon Cage (TN9): The glass fiber reinforced polyamide cage ensures quiet operation and excellent guidance of the balls. Its lightweight nature reduces centrifugal forces, making it ideal for high-speed applications.
- Precision Manufacturing & C3 Clearance: Built to ABEC 1 precision with a C3 radial internal clearance, this bearing accommodates thermal expansion and interference fits, ensuring stable performance under varying operational conditions.
- Pre-Lubricated for Immediate Use: Filled with a high-performance grease, the bearing is ready for installation and offers long-term, maintenance-free operation within its designated temperature range.
627-2RZTN9/C3GMG Bearing Typical Application Areas
This versatile and robust bearing is well-suited for a wide range of industrial and commercial equipment, including:
- Small Electric Motors: Ideal for spindle drives in power tools, appliance motors, and small industrial fans.
- Precision Instruments and Office Automation: Used in printers, scanners, copiers, and other devices requiring reliable, quiet operation.
- Pumps and Gearboxes: Suitable for light-duty pumps and transmission systems where radial loads are predominant.
- Material Handling Equipment: Applied in conveyor rollers and other automated handling systems.
- Automotive Auxiliary Units: Found in components like alternators, idler pulleys, and blower motors.
