635-2Z Bearing Product Overview & Core Advantages
The 635-2Z is a metric single row deep groove ball bearing designed for exceptional performance in compact, high-precision applications. Engineered with shielded protection (2Z) and pre-lubricated with grease, this bearing offers reliable operation and is maintenance-free for its service life. Its P6 tolerance class and CN radial internal clearance ensure high running accuracy and consistent performance, making it an ideal solution for applications demanding high rotational speeds and robust radial load capacity.
635-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 635 | Standard series designation for a deep groove ball bearing with a 5mm bore and 19mm OD. | Defines the core bearing dimensions for compatibility and interchangeability. |
| -2Z | Bearing is equipped with non-contact shields on both sides. | Provides effective protection against contamination while allowing for high-speed operation. |
635-2Z Bearing Structural Features & Performance Benefits
- Optimized Single Row Design: The deep groove raceway and high-precision construction enable the bearing to handle significant radial loads and moderate axial loads in both directions.
- Shielded Protection (2Z): The non-contact steel shields retain the factory-applied grease and effectively exclude contaminants like dust and debris, significantly enhancing bearing life and reliability without the friction associated with contact seals.
- High-Speed Capability: The combination of a stainless steel cage, optimized internal geometry, and effective grease lubrication allows for a high limiting speed of 40,000 rpm.
- Precision & Rigidity: Manufactured to a P6 tolerance class, this bearing ensures minimal runout and high positional accuracy. The CN clearance provides an optimal balance for most high-speed applications.
- Maintenance-Free Operation: Pre-lubricated with high-quality grease, the bearing is ready for immediate installation and delivers long-term, maintenance-free performance within its specified temperature range.
635-2Z Bearing Typical Application Areas
This precision bearing is ideally suited for a wide range of compact and high-speed machinery, including:
- Small Electric Motors and Spindles
- Precision Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Computer Cooling Fans
- Instrumentation and Control Devices
- Robotic Drives and Small Gearboxes
