61860 Bearing Product Overview & Core Advantages
The 61860 metric ball bearing is a precision-engineered single row deep groove ball bearing designed for demanding industrial applications. Engineered from high-grade chrome steel, this bearing excels in handling radial loads with exceptional reliability. Its open design and P6 tolerance class ensure high running accuracy, making it ideal for applications requiring precise rotational performance. The bearing's optimized internal geometry contributes to its high radial dynamic load rating of 38,667 lbf and smooth operation across a wide temperature range from -30° to 120 °C.
61860 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Significance |
|---|---|
| 61860 | Basic bearing designation indicating a metric single row deep groove ball bearing with 300mm bore, 380mm OD, and 38mm width |
| Open | No seals or shields, allowing for optimal lubrication access and heat dissipation |
| P6 | Higher precision tolerance class than standard, ensuring reduced runout and vibration |
| CN | Normal radial internal clearance suitable for most operating conditions |
61860 Bearing Structural Features & Performance Benefits
The 61860 bearing features a robust single row construction with precision-ground chrome steel rings and balls, delivering exceptional durability and wear resistance. The stainless steel cage provides superior guidance for the balls, maintaining optimal alignment and contributing to the bearing's high limiting speed of 2,000 rpm. The deep groove raceway design enables efficient radial load distribution while accommodating moderate axial loads in both directions. With a radial static load rating of 55,078 lbf, this bearing offers exceptional stability and longevity in heavy-duty applications. The precise dimensional tolerances ensure consistent performance and easy installation in precision machinery.
