Design Features
Self-aligning Capability
One of the most prominent features of the 222 series spherical roller bearings is its self-aligning function. The spherical outer ring raceway and two rows of barrel-shaped rollers enable the bearing to automatically compensate for shaft misalignment between the shaft and the housing. This feature ensures smooth operation even when there are angular errors, typically up to 1.5° – 2° under normal loads, reducing the risk of premature failure due to misalignment.
Robust Construction
These heavy duty bearings are constructed with high-quality bearing steel. The inner and outer rings are precisely machined to provide a smooth running surface for the rollers. The large-diameter rollers are designed to increase the contact area with the raceways, significantly enhancing the bearing’s load-carrying capacity. The cages, usually made of high-strength steel or brass, are engineered to maintain the correct separation and guidance of the rollers, ensuring stable operation at high speeds.
Performance Advantages
High Load Capacity
The Spherical Roller Bearing 222 Series excels in handling heavy radial loads and moderate axial loads in both directions. It can withstand substantial radial loads, making it an ideal choice for applications where the equipment is subjected to high-stress conditions. For example, in mining crushers, the 222 series bearings can support the massive weight of the rotating parts and the impact forces generated during the crushing process.
Excellent Vibration and Shock Resistance
Thanks to its robust design and high-quality materials, this series of bearings offers excellent resistance to vibration damping and shock. This makes it suitable for use in industries such as construction machinery, where equipment often operates in harsh and uneven environments. The bearings can effectively dampen vibrations, ensuring the stability of the machinery and reducing the wear and tear on other components.
Low Friction and High Efficiency
Advanced manufacturing techniques and precision-ground surfaces result in low friction within the bearing. This not only reduces energy consumption but also improves the overall efficiency of the machinery. In industrial motors, the use of 222 series bearings can lead to significant energy savings over time, contributing to a more sustainable operation.
