61805-2RZ Bearing Product Overview & Core Advantages
The 61805-2RZ 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 while offering protection against contamination. Manufactured to a P6 tolerance class, it ensures high running accuracy, making it suitable for precision mechanisms where space is limited and operational reliability is critical.
61805-2RZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61805 | Basic series code for a metric, single row deep groove ball bearing with a 25mm bore and 37mm outside diameter. |
| 2RZ | Designates non-contact rubber seals on both sides of the bearing. The "2" indicates two seals, and "RZ" specifies low-friction, non-contact type seals, offering effective protection against dust and moisture with minimal impact on limiting speed. |
61805-2RZ Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: The single row deep groove raceway and high-grade chrome steel construction provide a high radial dynamic load rating of 980 lbf, enabling reliable performance under substantial loads.
- Sealed & Pre-Lubricated for Long Life: Fitted with 2RZ non-contact seals on both sides and pre-lubricated with grease, this bearing is effectively shielded from contaminants and is maintenance-free for the majority of its service life, enhancing operational reliability.
- Precision & High-Speed Capability: Manufactured to P6 tolerance and featuring a low-friction stainless steel cage, the bearing supports smooth operation and a high limiting speed of 19,000 rpm, making it suitable for demanding high-speed applications.
- Compact & Lightweight Design: With a cross-section of just 7mm in width and a weight of only 0.022 kg, it is an ideal solution for applications with severe space and weight constraints.
