61817 Bearing Product Overview & Core Advantages
The 61817 metric ball bearing is a single row deep groove ball bearing designed for exceptional performance in applications demanding high precision and reliability. Its primary function is to support radial loads efficiently. Engineered with a P6 tolerance class and CN radial internal clearance, this bearing offers superior running accuracy, making it ideal for high-speed operations up to 7,500 rpm. Its compact design, with a 13 mm width, allows for space-saving integration into various mechanical assemblies.
61817 Bearing Model Code Explained, Specifications & Naming Convention
The model number 61817 follows a standard metric designation. The key specifications defining its performance are not encoded in a complex suffix but are inherent in its standard construction and the detailed specifications provided.
- Seal Type: Open - Allows for versatile lubrication options but requires a clean operating environment or external sealing.
- Tolerance Class: P6 - Denotes a higher precision grade than standard, ensuring tighter dimensional control and reduced runout for smoother operation.
- Radial Internal Clearance: CN - Indicates a "normal" clearance range, suitable for a wide array of general applications and operating conditions.
- Lubrication: None - The bearing is supplied without grease, providing flexibility for the user to apply a lubricant optimized for their specific speed and temperature requirements.
61817 Bearing Structural Features & Performance Benefits
The performance of the 61817 bearing is a direct result of its robust construction and material selection.
- High-Speed Capability: The combination of a stainless steel cage, chrome steel rings and balls, and P6 precision enables stable operation at high rotational speeds, with a limiting speed of 7,500 rpm.
- High Load Capacity: With a dynamic load rating of 4384 lbf and a static load rating of 3732 lbf, this bearing is capable of handling significant radial loads, ensuring long service life and reliability.
- Precision & Rigidity: The single row deep groove design, manufactured to a P6 tolerance, provides high running accuracy and consistent performance, which is critical for applications requiring minimal vibration and precise shaft positioning.
- Material Integrity: Constructed from high-grade chrome steel for the rings and balls, and a stainless steel cage, the bearing offers excellent durability and resistance to wear. It is also compliant with ROHS and REACH environmental standards.
