The 628-2RS is a compact, single-row deep groove ball bearing engineered for space-constrained applications requiring reliable performance under light to moderate loads. Featuring dual RS-type rubber seals, this bearing provides effective protection against dust, moisture, and other contaminants while retaining lubrication for extended service life. With an 8 mm bore and 8 mm width, it is the preferred choice for small electric motors, power tools, and automation equipment where sealing and low friction are critical.
