Deep Groove sealed Ball Bearing 61903-2Z
Deep groove ball bearing feature :
1. The most representative of the rolling bearings, widely used
2. Outer ring with a ring or flange bearing, that is easy to axial positioning, and easy to install the shell;
3. The maximum load bearing size is the same as the standard bearing, but the inner and outer rings have a trough, which increases the number of balls and improves the rated load.
Single Row Deep Groove Ball Bearing main purpose:
Deep groove ball bearings can be used for transmission, instrumentation, motors, household appliances, internal combustion engines, transport vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo
Single Row Deep Groove Ball Bearing Features:
1:Can withstand radial load and bidirectional axial load
2:Suitable for high-speed rotation and require low noise, low vibration of the occasion
3:With a steel plate dust cover or rubber seal seal bearing in advance filled with the right amount of grease;
