💡 What is a deep groove ball bearing used for in micro motors and linear slide unit applications? Deep groove ball bearings are handy for supporting radial and axial loads in tight rotating assemblies. - Ideal for micro motors, small rotary motors, office equipment and linear slide units where low friction and high speed matter. - Shielded and sealed ball bearing options protect against contamination; sealed types offer more liquid resistance while shielded bearings allow higher limit speeds. - Pre-lubricated ABEC-1 bearings reduce maintenance and fit pillow block and miniature housings for smooth motion control.
