Its key advantage lies in its ability to handle significant radial loads while offering protection against contamination. Manufactured to a P6 tolerance class, it provides high running accuracy, making it an ideal precision bearing for demanding industrial environments.
61813-2RZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61813 | Basic model number for a single row deep groove ball bearing with a 65mm bore and 85mm outside diameter. |
| -2RZ | Specifies non-contact rubber seals on both sides of the bearing. The "2" indicates two seals, and "RZ" denotes low-friction, non-contact type seals that provide effective protection against contaminants with minimal impact on limiting speed. |
61813-2RZ Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built with chrome steel rings and balls and a stainless steel cage, this bearing offers a high radial dynamic load rating of 2788 lbf and a radial static load rating of 2855 lbf, ensuring durability and long service life under demanding conditions.
- Sealed & Pre-Lubricated for Longevity: The non-contact 2RZ seals effectively shield the internal components from dust and moisture while retaining the factory-applied grease lubrication. This combination creates a maintenance-free solution, reducing downtime and operational costs.
- Precision & High-Speed Capability: Manufactured to a P6 tolerance class with a standard CN radial internal clearance, it ensures high running accuracy and smooth operation. The optimized design and seals allow for a limiting speed of 8,000 rpm, making it suitable for high-speed applications.
- Compact & Lightweight Design: With cross-sectional dimensions of 65mm x 85mm x 10mm and a weight of only 0.13 kg, it is an excellent choice for applications where space and weight are critical constraints.
