61814-2RZ Bearing Product Overview & Core Advantages
The 61814-2RZ is a metric single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. This sealed bearing excels in handling significant radial loads and moderate axial loads in one direction. Its key advantages include a high limiting speed of 7,500 rpm, consistent operation within a wide temperature range (-30°C to 120°C), and long service life due to its pre-lubricated and sealed construction, making it an ideal choice for applications demanding precision and durability in a confined space.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning |
|---|---|
| 61814 | Basic bearing series designation, indicating a metric, single row deep groove ball bearing with a 70mm bore, 90mm OD, and 10mm width. |
| 2RZ | Signifies non-contact seals on both sides of the bearing. The "2" indicates two seals, and "RZ" denotes low-friction, non-contact rubber seals, offering excellent protection against contaminants with minimal impact on rotational speed. |
61814-2RZ Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing provides high strength and corrosion resistance. It supports a radial dynamic load rating of 2788 lbf and a radial static load rating of 2967 lbf, ensuring reliable performance under demanding conditions.
- Optimized for High-Speed Operation: The combination of a low-friction stainless steel cage and the non-contact 2RZ seals enables a high limiting speed, making it suitable for applications requiring rapid rotation.
- Precision & Long-Term Reliability: Built to P6 tolerance class and standard CN radial internal clearance, it offers precise running accuracy. The factory-applied grease lubrication and effective sealing create a maintenance-free solution for the bearing's operational lifespan.
- Compact and Lightweight: With a cross-section of just 10mm and a weight of only 0.14 kg, it is an excellent solution for space-constrained and weight-sensitive designs.
