61818-2RZ Bearing Product Overview & Core Advantages
The 61818-2RZ is a single row deep groove ball bearing designed for high-performance applications requiring reliable operation and compact design. This metric sealed bearing excels in handling primarily radial loads and is characterized by its high precision P6 tolerance class. Its key advantages include a robust sealed construction for contaminant exclusion, pre-lubrication for maintenance-free operation, and a high limiting speed of 5,600 rpm, making it an ideal choice for applications demanding high reliability and long service life.
61818-2RZ Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning & Advantage |
|---|---|---|
| Basic Designation | 61818 | Denotes a single row deep groove ball bearing series with a 90mm bore, 115mm OD, and 13mm width. |
| Seal Type | 2RZ | Specifies non-contact seals on both sides. The "RZ" suffix indicates low-friction seals effective at excluding contaminants while maintaining high-speed capability. |
61818-2RZ Bearing Structural Features & Performance Benefits
The performance of the 61818-2RZ is derived from its carefully engineered components and construction:
- High-Grade Materials: Manufactured from chrome steel rings and balls with a stainless steel cage, ensuring high strength, durability, and corrosion resistance.
- Sealed & Pre-Lubricated Design: The 2RZ non-contact seals protect the bearing interior from dust and moisture. Combined with factory-applied grease lubrication, this creates a maintenance-free system ideal for sealed-for-life applications.
- High-Speed Capability: The optimized internal geometry and low-friction seal design contribute to a high limiting speed of 5,600 rpm.
- Precision Performance: Built to a P6 tolerance class with a standard CN radial internal clearance, ensuring precise running accuracy and consistent performance in demanding applications.
