623-2Z/C3 Bearing Product Overview & Core Advantages
The 623-2Z/C3 is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. This shielded bearing features a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Its construction from chrome steel provides excellent durability and wear resistance. The integrated shields (2Z) protect against contamination while the ABEC 1 precision ensures consistent operation, making it an ideal choice for high-speed applications requiring dependable radial load capacity.
623-2Z/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 623 | Basic bearing series with 3mm bore diameter | Compact design for space-constrained applications |
| 2Z | Double shielded both sides | Effective contamination protection, extended service life |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, ideal for interference fits |
623-2Z/C3 Bearing Structural Features & Performance Benefits
Deep Groove Design: The optimized raceway geometry enables excellent radial load capacity while accommodating moderate axial loads in both directions, providing versatile performance in various applications.
Double Shield Protection: The 2Z shields effectively retain lubrication and exclude contaminants, significantly enhancing bearing reliability and reducing maintenance requirements in demanding environments.
C3 Internal Clearance: The greater radial clearance compensates for thermal expansion differences between shaft and housing, preventing premature failure in applications with temperature variations or interference fits.
High-Speed Capability: With a limiting speed of 50,000 rpm and precision ABEC 1 manufacturing, this bearing delivers smooth operation at high rotational speeds while maintaining dimensional stability.
