6212-RS1Z/C3 GJN Bearing Product Overview & Core Advantages
The 6212-RS1Z/C3 GJN is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its primary advantage lies in its versatile sealing solution, featuring one side shielded and one side sealed, which provides robust protection against contamination while retaining lubrication. Manufactured to ABEC 1 | ISO P0 tolerance standards and featuring a C3 radial internal clearance, this bearing is optimized for applications with thermal expansion or where a slightly looser fit is required, ensuring stable performance under a wide temperature range of -30° to 120 °C. It is designed to handle significant radial loads efficiently.
6212-RS1Z/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6212 | Basic model number denoting a single row deep groove ball bearing with a 60mm bore and 110mm outside diameter. |
| -RS1Z | Specifies the sealing configuration: RS1 indicates a contact seal on one side, and Z indicates a non-contact shield on the other side. |
| /C3 | Denotes a greater than normal radial internal clearance, suitable for applications with higher operational temperatures or interference fits. |
| GJN | Indicates the cage design and material. GJN typically refers to a glass fiber reinforced polyamide 66 cage, offering quiet operation and suitability for high speeds. |
6212-RS1Z/C3 GJN Bearing Structural Features & Performance Benefits
- Optimized Sealing for Versatility: The combination of a contact seal (RS1) on one side and a non-contact shield (Z) on the other offers an excellent balance. The seal effectively retains grease and excludes contaminants, while the shield minimizes friction, making the bearing suitable for a wide range of environments and contributing to its limiting speed of 5,600 rpm.
- High Load Capacity: Built from chrome steel for both rings and balls, the bearing provides a high radial dynamic load rating of 1178 lbf and a radial static load rating of 8138 lbf, ensuring durability and long service life under substantial radial loads.
- Stable Performance with C3 Clearance: The C3 radial internal clearance accommodates thermal expansion in the shaft or housing, preventing preload and potential seizure, which is critical for maintaining performance in applications with variable operating temperatures.
- Lightweight & High-Speed Cage: The GJN polyamide cage is lightweight, which reduces centrifugal forces, and offers good sliding properties, contributing to lower operating temperatures and higher achievable speeds.
