635-2Z/C3GJN Bearing Product Overview & Core Advantages
The 635-2Z/C3GJN is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable operation under radial loads. Featuring shielded construction (2Z) and a C3 radial internal clearance, this bearing offers robust protection against contamination while accommodating thermal expansion in demanding environments. Manufactured to ABEC 1 | ISO P0 tolerance standards with all-chrome steel components, it delivers consistent precision and durability. The combination of compact dimensions (5mm bore, 19mm OD, 6mm width) and high limiting speed (32,000 rpm) makes it ideal for space-constrained, high-speed applications.
635-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 635 | Standard deep groove ball bearing series | Proven design for radial load capacity |
| 2Z | Double-sided steel shields | Superior contamination protection without contact friction |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-speed applications |
| GJN | Grease type designation | Optimized lubrication for specified temperature range |
635-2Z/C3GJN Bearing Structural Features & Performance Benefits
Shielded Design Excellence: The double-sided steel shields (2Z) provide effective protection against dust and particulate contamination while maintaining low friction operation, enabling high rotational speeds up to 32,000 rpm.
Optimized Internal Clearance: The C3 radial clearance ensures reliable performance under thermal expansion conditions, making this bearing suitable for applications with varying operational temperatures (-30° to 120°C).
Premium Material Construction: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing delivers exceptional hardness, wear resistance, and dimensional stability under dynamic load ratings of 447 lbf.
Precision Engineering: Built to ABEC 1 | ISO P0 tolerance class, the bearing maintains consistent running accuracy with tight dimensional control on bore, outside diameter, and width.
