Product Structure

The SG10 RS bearing is a miniature deep groove ball bearing with an inner diameter of 4 mm, outer diameter of 13 mm, and width of 6 mm. It features a single-sided contact rubber seal (RS design) that effectively prevents grease leakage and blocks external contaminants. The bearing is made of high-carbon chromium steel, precision-ground and heat-treated, with a cage typically constructed from stamped steel or engineering plastic to ensure smooth rolling element operation. Its compact and reliably sealed structure makes it suitable for light to medium load applications.


Key Performance Features of U693 ZZ

The SG10 RS bearing offers excellent dust and leakage protection, with its rubber seal effectively blocking dust, moisture, and other particles to extend service life. It operates smoothly with low noise, making it suitable for high-speed rotation. Made from high-quality steel and precision manufacturing processes, it provides strong wear resistance and fatigue strength. The pre-lubricated design reduces maintenance needs, and its easy installation and cost-effectiveness make it an ideal choice for various small-scale machinery applications.


Main Application Scenarios

The SG10 RS bearing is widely used in small motors, household appliances (such as fans and washing machines), office equipment (like printers and scanners), power tools, medical devices, and automated instruments. It is also common in light industrial machinery, conveyor systems, automotive components (e.g., wiper motors), and fitness equipment. Its sealing and reliability make it perform exceptionally in environments requiring dust protection or low to medium-speed rotation, suitable for OEM replacement or maintenance projects.
