6205-RS1Z/C3 Bearing Product Overview & Core Advantages
The 6205-RS1Z/C3 is a single row deep groove ball bearing designed for reliable performance in demanding applications. Its key advantage lies in its versatile sealing solution, featuring one side shielded and one side sealed, offering a balance between contaminant exclusion and low friction. Manufactured to ABEC 1 | ISO P0 tolerance class, it ensures consistent operation and is pre-set with a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. This bearing is engineered to handle significant radial loads and is an excellent choice for general industrial use where robustness and cost-effectiveness are paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6205 | Standard bearing series designation indicating a metric, single row deep groove ball bearing with a 25 mm bore, 52 mm OD, and 15 mm width. |
| RS1 | Indicates a contact seal (typically NBR rubber) on one side, providing superior protection against contaminants and moisture. |
| Z | Indicates a steel shield on the opposite side, offering basic protection with minimal friction. |
| /C3 | Specifies a radial internal clearance greater than normal (C0), suitable for applications with shaft interference fits or where operational heat generation is expected. |
6205-RS1Z/C3 Bearing Structural Features & Performance Benefits
- Hybrid Sealing Configuration: The combination of a contact seal (RS1) on one side and a non-contact shield (Z) on the other provides an optimal balance. The sealed side offers excellent exclusion of dirt and moisture, while the shielded side minimizes friction and heat generation, contributing to a higher limiting speed of 13,000 rpm.
- Robust Load Capacity: Constructed entirely from chrome steel (rings, balls, and cage), this bearing delivers a high radial dynamic load rating of 3147 lbf and a radial static load rating of 1765 lbf, ensuring durability under significant loads.
- Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion, preventing premature failure due to excessive preload and ensuring smooth running.
- Precision Engineering: Manufactured to ABEC 1 precision standards, it guarantees consistent bearing dimensions and running accuracy, reducing vibration and noise for reliable performance.
6205-RS1Z/C3 Bearing Typical Application Areas
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
