⚙️Type and Structure:
SB208-50ZZ CS is a type of SB insert ball bearing. Its feature is that there is an extension part on one side of the inner ring, usually with two locking devices at 120° angles, used to fix the bearing on the shaft. "ZZ" indicates that metal sealing covers are installed on both sides of the bearing, which can prevent dust, impurities, etc. from entering the interior of the bearing.
SB208-50ZZ CS made of chrome steel GCR15, it has high hardness and wear resistance, and can withstand certain radial loads. The metal sealing covers on both sides can effectively protect the rolling elements and lubricating grease inside the bearing, thereby extending the service life of the bearing.
