6213-2Z 65x120x23mm Double Metal Shield Single Row Deep Groove Ball Bearing

1. Product Overview

6213-2Z is standard metric single row deep groove ball bearing with overall dimension 65×120×23mm. 2Z stands for double-sided non-contact stamped metal dust shields, which lock internal grease inside and block dry dust, powder and fine solid impurities without increasing rotation torque. Deep raceway structure bears radial load and bidirectional light & medium axial load simultaneously, matched super-finished raceway and high-precision steel balls deliver stable high-speed operation, low vibration and quiet performance. Pre-filled long-life industrial grease realizes maintenance-free running, widely applied to industrial driving motors, large cooling fans, medium-duty gearboxes, agricultural water pumps, light construction auxiliary equipment and general automation transmission assemblies.
