6018-2Z Bearing Product Overview & Core Advantages
The 6018-2Z is a metric single row deep groove ball bearing engineered for high-performance applications requiring reliable operation and long service life. This shielded bearing is designed to primarily handle radial loads while also accommodating moderate axial loads in both directions. Its construction from high-grade chrome steel and inclusion of stainless steel shields ensure excellent durability and resistance to contamination. Pre-lubricated with grease, it offers a ready-to-install solution, making it ideal for applications demanding low maintenance and consistent performance within a wide operating temperature range.
Model Code Breakdown
| 6018 | Basic series code indicating a metric single row deep groove ball bearing with a 90mm bore and 140mm outside diameter. |
| 2Z | Signifies that the bearing is equipped with non-contact shields on both sides. These shields protect the internal components from large particulate contaminants while minimizing friction and heat generation, contributing to the bearing's high limiting speed. |
6018-2Z Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from hardened chrome steel for both rings and balls, the 6018-2Z offers a high radial dynamic load rating of 13,601 lbf and a radial static load rating of 11,240 lbf, ensuring reliable performance under significant stress.
- Optimized for Speed & Low Maintenance: The stainless steel cage provides stability at high rotational speeds, supporting a limiting speed of 5,000 rpm. The combination of non-contact shields and factory-applied grease lubrication creates a sealed, maintenance-free environment for the bearing's service life.
- Precision & Reliability: Built to P6 tolerance class and standard CN radial internal clearance, this bearing ensures precise running accuracy and smooth operation, which is critical for applications requiring minimal vibration and noise.
6018-2Z Bearing Typical Application Areas
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
