629-2Z/C3GJN Bearing Product Overview & Core Advantages
The 629-2Z/C3GJN is a metric single row deep groove ball bearing engineered for reliable performance in demanding applications. This shielded bearing excels in handling radial loads with high efficiency, featuring a generous C3 radial internal clearance suitable for applications with thermal expansion or shaft misalignment. Its compact design, combined with ABEC 1 precision and chrome steel construction, makes it an ideal choice for applications requiring robust performance and consistent operation.
629-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 629 | Basic series designation for a single row deep groove ball bearing. |
| 2Z | Indicates non-contact shields on both sides, providing effective protection against contaminants while minimizing friction. |
| C3 | Specifies a greater than normal radial internal clearance, ideal for applications with thermal gradients or where fits result in clearance reduction. |
| GJN | Indicates the bearing is supplied without lubrication (grease), allowing for application-specific lubricant selection. |
629-2Z/C3GJN Bearing Structural Features & Performance Benefits
Optimized for Radial Load Capacity: The single row deep groove raceway geometry is precision-engineered to carry significant radial dynamic loads (873 lbf) efficiently, ensuring long service life.
Enhanced Operational Reliability: The non-contact ZZ shields effectively exclude large particulate contaminants while maintaining low running torque, contributing to a limiting speed of 28,000 rpm. The C3 clearance provides operational stability in environments prone to thermal expansion.
Robust Material Construction: Manufactured from high-grade chrome steel for rings, balls, and cage, this bearing offers excellent durability, wear resistance, and consistent performance across a temperature range of -30°C to 120°C.
Precision and Compliance: Built to ABEC 1 (ISO P0) tolerance standards, it ensures reliable fit and function. The bearing is also ROHS and REACH compliant, meeting stringent environmental regulations.
