temperature (-20 ~ 90 degrees Celsius)..
It is usually used in the machine interior, where there is enough oil, and the shielding on both sides of the bearing can prevent the entry of grease and pollutants. (You can use 2RS bearing to clean the internal grease, which is equivalent to opening the bearing).
Deep groove ball bearings have deep, uninterrupted raceway grooves. These raceway grooves and the ball form a tight expansion, so that the bearing can withstand bidirectional radial load and axial load. Deep groove ball bearings can be opened or covered, and the ball is protected from dust by a shield (with a seal or shield)..
