E2.607-2Z/C3 Bearing Product Overview & Core Advantages
The E2.607-2Z/C3 is a metric single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load capacity and operational stability. Its compact design, featuring a 7mm bore and 19mm outside diameter, makes it ideal for space-constrained assemblies. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent precision. A key advantage is its C3 radial internal clearance, which accommodates thermal expansion, making it suitable for applications with potential temperature fluctuations. The inclusion of integrated shields (2Z) provides robust contaminant protection, enhancing service life in challenging environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| E2.607 | Basic bearing designation indicating a specific single row deep groove ball bearing series with a 7mm bore and 19mm outside diameter. |
| 2Z | Signifies the bearing is equipped with non-contact shields on both sides. This provides effective protection against solid contaminants while maintaining a low torque signature and allowing for high speeds. |
| /C3 | Indicates a greater than normal radial internal clearance. This is advantageous in applications where thermal expansion of the shaft or housing is expected, preventing preload and potential bearing failure. |
E2.607-2Z/C3 Bearing Structural Features & Performance Benefits
- Robust Construction for High Load Capacity: Manufactured entirely from chrome steel for the rings, balls, and cage, this bearing offers high strength and durability, supporting a radial dynamic load rating of 526 lbf and a static load rating of 214 lbf.
- Optimized for High-Speed Operation: The deep groove raceway and precision-ground components contribute to smooth operation, enabling a limiting speed of 43,000 rpm. The steel cage ensures stability and integrity at these high rotational velocities.
- Effective Contamination Protection: The 2Z shields on both sides act as a physical barrier against dust and debris, significantly extending the bearing's operational life in unclean environments. This design also helps to retain any subsequently applied lubricant.
- Accommodates Thermal Expansion: The C3 clearance is a critical feature for applications with variable operational temperatures or where fit interferences could reduce internal clearance. It prevents excessive preload, reducing friction, heat generation, and the risk of seizure.
E2.607-2Z/C3 Bearing Typical Application Areas
The E2.607-2Z/C3 is versatile and finds use in a wide range of compact, high-speed machinery and devices. Common applications include:
- Small Electric Motors: Ideal for spindle and rotor support in fractional horsepower motors, fans, and blowers.
- Precision Instruments and Medical Devices: Used in scanners, pumps, and small gearboxes where reliable, low-noise operation is critical.
- Office Automation Equipment: Suitable for printers, copiers, and scanners.
- Power Tools and Automotive Auxiliary Drives: Provides durable performance in demanding, high-RPM environments.
