6218-2RS1/C3 Bearing Product Overview & Core Advantages
The 6218-2RS1/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. As a metric sealed bearing, it excels in handling significant radial loads while offering protection against contamination. Its key advantages include a generous C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. The combination of chrome steel construction and high-quality sealing ensures long service life and reliable operation across a wide temperature range.
6218-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6218 | Basic bearing designation: 60 series deep groove ball bearing with 90mm bore and 160mm OD. |
| 2RS1 | Contact seals on both sides, providing superior protection against contaminants and retaining lubricant. |
| C3 | Radial internal clearance greater than Normal (C0) group. Ideal for applications with shaft interference fits or elevated operating temperatures. |
6218-2RS1/C3 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from high-grade chrome steel for both rings, balls, and cage, this bearing delivers high strength and durability under radial dynamic load ratings of 21,604 lbf.
Enhanced Sealing: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, significantly extending bearing life in harsh environments.
Optimized Internal Clearance: The C3 clearance accommodates thermal expansion and press fits, preventing premature failure due to excessive preload and ensuring stable operation.
Precision & Speed: Built to ABEC 1 | ISO P0 tolerance standards, it offers reliable performance at a limiting speed of 4,000 rpm, suitable for a wide range of industrial speeds.
