6021-RS1/C3 Bearing Product Overview & Core Advantages
The 6021-RS1/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This sealed bearing features a robust construction that provides reliable radial load capacity and moderate axial loads in both directions. Its key advantages include a generous C3 radial internal clearance for applications involving thermal expansion, and integrated sealing for contaminant protection. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a dependable balance of precision, durability, and value for high-reliability machinery.
6021-RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 6021: Basic designation indicating a single row deep groove ball bearing with a 105mm bore and 160mm outside diameter.
- RS1: Denotes the seal type. This bearing features a contact rubber seal on one side, providing effective protection against contaminants and retention of lubricant.
- C3: Specifies the radial internal clearance group. A C3 clearance is greater than the standard CN group, making it suitable for applications where thermal expansion of the shaft or housing is expected, or where high operating temperatures are present.
6021-RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built with chrome steel rings, balls, and cage, this bearing delivers a high radial dynamic load rating of 16,254 lbf and a static load rating of 14,792 lbf, ensuring long service life under significant loads.
- Integrated Sealing for Enhanced Reliability: The RS1 seal effectively shields the internal components from dust, moisture, and other contaminants, while also retaining lubricant. This contributes to extended service intervals and consistent performance in harsh environments.
- Optimized for Thermal Applications: The C3 radial internal clearance accommodates dimensional changes due to thermal expansion during operation, preventing premature failure from excessive preload and ensuring stable performance across its temperature range of -30°C to 120°C.
- Precision & Speed Performance: Manufactured to ABEC 1 precision, it ensures smooth operation and reliable performance at its limiting speed of 4,000 rpm.
