Selection guide: 2RS double gasket, suitable for harsh outdoor environment and medium temperature (-20~90 degrees Celsius) occasions. It is usually used inside the machine with sufficient oil, and the protective covers on both sides of the bearing can prevent grease and impurities from entering. (You can use the 2RS bearing to clean the internal grease, which corresponds to the opening of the bearing).
Deep groove ball bearings have deep and continuous running grooves. These raceway grooves and balls form a tight expansion so that the bearing can withstand bi-directional radial load and axial load. Deep groove ball bearings can be opened or covered, and a protective cover (with seal or protective cover) protects the ball from dust.
