basic information
<Sleeve Bearing> Advantages: - High impact resistance - The most affordable bearing type Disadvantages: - Slow start due to friction, requiring more drive energy - Uneven wear may occur depending on the installation angle, so it cannot be installed at arbitrary angles - Gases generated by friction may remain in the bearing, solidify, and clog the bearing - Short lifespan <Ball Bearing> Advantages: - Quick start and low drive energy due to less friction - Springs between bearings suppress rotor tilt, allowing use at arbitrary angles - Long lifespan Disadvantages: - Inferior impact resistance - Relatively high noise level - Higher cost <omniCOOL System Bearing> Advantages: - Less friction and accumulation of lubricant - Reduced noise level - Priced similarly to sleeve bearings - Improved lifespan compared to sleeve bearings *For details on the main lineup, please check the "Related Links" above.*
