61810 Bearing Product Overview & Core Advantages
The 61810 is a single row deep groove ball bearing designed for compact applications requiring high precision and reliability. As a metric bearing, it excels in handling radial loads efficiently. Its key advantages include a P6 tolerance class for superior dimensional accuracy and a CN radial internal clearance suitable for a wide range of operating conditions. The open design, combined with high-grade components, makes it an ideal choice for applications demanding smooth operation and long service life.
61810 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 618 | Series designation for extra thin-section, deep groove ball bearings. |
| 10 | Indicates a bore diameter of 50 mm (bore = 10 x 5 mm). |
| Open | No seals or shields, allowing for higher speeds and custom lubrication. |
| P6 | Tolerance class indicating higher running accuracy than standard (P0) bearings. |
| CN | Standard (Normal) group radial internal clearance. |
61810 Bearing Structural Features & Performance Benefits
Optimized for Compact Design & High Precision: The single row deep groove geometry and a cross-section of just 7 mm in width make this bearing exceptionally space-saving. The stainless steel cage ensures low friction and reliable guidance of the balls, contributing to smooth operation.
Superior Load Capacity & Rigidity: Manufactured from chrome steel for both rings and balls, the bearing offers a high radial dynamic load rating of 1520 lbf and a radial static load rating of 1529 lbf, providing robust performance under demanding conditions.
High-Speed Capability: The open design and precision P6 tolerance enable a high limiting speed of 13,000 rpm, making it suitable for high-speed applications.
Versatile Application Range: With an operating temperature range of -30°C to 120°C and no pre-applied lubrication, it offers flexibility for various environmental conditions and allows for the use of specialized lubricants.
