629-2ZJEM Bearing Product Overview & Core Advantages
The 629-2Z JEM is a single row deep groove ball bearing designed for reliable performance in various industrial applications. This metric bearing features shielded protection on both sides, effectively preventing contamination from entering while retaining lubrication. Engineered with chrome steel components and manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent operation and extended service life. Its compact design with an 8 mm width makes it ideal for space-constrained assemblies requiring radial load capacity and moderate speed operation.
629-2ZJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 629 | Basic bearing series designation for single row deep groove ball bearings |
| 2Z | Non-contact shields on both sides for contamination protection |
| JEM | Manufacturer-specific suffix indicating special processing or quality standards |
629-2ZJEM Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The deep groove raceway design enables efficient handling of radial loads while accommodating moderate axial loads in both directions. With a dynamic load rating of 873 lbf and static load rating of 357 lbf, this bearing provides reliable performance under various operating conditions.
Controlled Operation Environment: The double-shielded (2Z) construction creates a protected internal environment, significantly reducing the risk of contamination-induced failure. This feature is particularly valuable in applications where maintenance access is limited.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with CN radial internal clearance, this bearing ensures smooth operation and consistent performance. The all-chrome steel construction (rings, balls, and cage) provides uniform thermal expansion characteristics and excellent durability.
Speed Capability: With a limiting speed of 28,000 rpm, this bearing is suitable for moderate to high-speed applications. The optimized cage design and precision components contribute to stable operation across the speed range.
629-2ZJEM Bearing Typical Application Areas
- Electric Motors - Small to medium-sized motors requiring reliable radial bearing support
- Power Tools - Compact designs where space constraints and contamination protection are critical
- Office Equipment - Printers, scanners, and copiers needing quiet, maintenance-free operation
- Medical Devices - Small instruments and equipment requiring precision motion components
- Automotive Components - Auxiliary systems, pumps, and small electric actuators
- Material Handling Equipment - Conveyor systems and small gearboxes
