61905 Bearing Product Overview & Core Advantages
The 61905 is a single row deep groove ball bearing designed for exceptional performance in precision applications. Characterized by its compact cross-section with a 9 mm width, this bearing excels at handling primarily radial loads and offers high operational reliability. Manufactured to a P6 tolerance class, it ensures superior running accuracy, making it an ideal component for systems demanding high rotational precision and smooth operation.
61905 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61905 | Indicates a metric, single row deep groove ball bearing series (619) with a 25 mm bore diameter (05). |
| (Implied Open) | The bearing features an open design without seals or shields, allowing for higher limiting speeds and facilitating direct lubrication access. |
| (Implied P6) | Denotes a tolerance class superior to standard (ABEC 1), providing tighter dimensional control for enhanced precision. |
61905 Bearing Structural Features & Performance Benefits
High-Precision Construction: The single row design with a stainless steel cage ensures stable operation and minimal vibration, which is critical for high-speed applications up to 22,000 rpm.
Robust Load Capacity: With a dynamic load rating of 1578 lbf and a static load rating of 967 lbf, this bearing offers reliable performance under significant radial loads.
Superior Material Integrity: Both rings and balls are made from chrome steel, providing high hardness, wear resistance, and a long operational lifespan.
Optimized for Custom Lubrication: The open seal type allows for the use of specialized lubricants tailored to specific operational environments and temperature ranges (-30°C to 120°C).
