Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61821 | Basic series designation for a metric, single row deep groove ball bearing with a specific bore diameter of 105 mm. |
| 2RS1 | Indicates the bearing is fitted with two contact seals, one on each side. The "RS1" suffix denotes synthetic rubber seals that provide superior protection against contaminants and moisture retention. |
61821-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealing & Lubrication: The 2RS1 contact seals effectively shield the internal components from dust, dirt, and moisture, while the pre-filled grease ensures consistent lubrication. This combination delivers a maintenance-free operational life and enhances reliability in challenging environments.
- High Load Capacity & Precision: Constructed from chrome steel rings and balls, the bearing offers a high dynamic load rating of 4676 lbf and a static load rating of 4406 lbf. The P6 tolerance class guarantees tight dimensional control and precise running performance, contributing to reduced vibration and noise.
- Optimized Cage & Speed Performance: The stainless steel cage provides excellent strength and corrosion resistance, contributing to stable operation and a high limiting speed of 2,800 rpm.
- Wide Operating Range: With a specified operating temperature range of -30°C to 120°C and standard CN radial internal clearance, the bearing is versatile for use in various industrial climates and applications.
