Motor – Low-Noise Bearing

Features: Deep-groove ball bearings are the most widely used type of rolling bearing in electric motors, primarily due to their quiet operation and additional advantages such as high speed capability and low friction. These bearings can accommodate radial loads as well as axial loads in both directions, making them suitable for use as locating bearings. In typical motor designs, one end is fixed while the other is floating to compensate for shaft expansion and contraction during operation; alternatively, a wave‑shaped washer can be fitted to the outer ring of the floating‑end bearing to apply preload and further reduce noise. Our company’s motor bearings offer a rated dynamic load capacity (Cr) comparable to standard models, with axial load‑carrying capacity improved by more than 20%. Bearing vibration levels are significantly reduced, resulting in a noise reduction of 1–2 grades. They are well suited for high‑speed applications, with a maximum permissible speed increased by over 150%, and under high‑speed conditions, temperature rise can be lowered by up to 20°C. Additionally, they exhibit enhanced wear resistance and impact resistance. With broad applicability, these bearings are also suitable for 80% of other applications that typically employ deep‑groove ball bearings.
