61900-2RS1 Bearing Product Overview & Core Advantages
The 61900-2RS1 is a miniature deep groove ball bearing designed for applications requiring compact dimensions and reliable performance. As a metric single row sealed bearing, it excels in handling radial loads efficiently within a confined space. Its primary advantages include a robust sealed design for contamination protection, high precision P6 tolerance for smooth operation, and pre-lubrication for immediate use, making it ideal for high-reliability and low-maintenance scenarios.
61900-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 61900 | Series designation for a miniature deep groove ball bearing with a 10mm bore. |
| 2RS1 | Indicates the bearing is fitted with two contact seals (RS1 type) on both sides, providing excellent protection against contaminants and retaining lubricant. |
61900-2RS1 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 10mm x 22mm x 6mm and a weight of only 0.0096 kg, this bearing is engineered for space-constrained applications without sacrificing performance.
- Superior Sealing & Lubrication: The 2RS1 contact seals effectively shield the internal components from dust and moisture, while the pre-applied grease lubrication ensures smooth operation from the start and offers a long service life, reducing maintenance needs.
- High Precision & Load Capacity: Manufactured to P6 tolerance class and featuring a CN radial internal clearance, it provides high running accuracy. The chrome steel rings and balls, combined with a stainless steel cage, deliver a dynamic load rating of 607 lbf and a static load rating of 286 lbf for reliable performance under radial loads.
- Wide Operating Range: The bearing operates effectively within a temperature range of -30°C to 120°C, making it suitable for various environmental conditions.
