10 PCS 3D Printer Flange Ball Bearing

Description:
Ball bearings help to reduce friction in 3D printer. It usually used in combination with timing belts.
Flange mounted bearings are used when the shaft axis is perpendicular to the bearing mounting surface. 
These ball bearings are suitable for both radial and axial movements at high speeds. They incorporate a sealed bearing that is preassembled into a flanged housing. The housing contains a precision ground surface perpendicular to the bearing axis and two, three or four mounting holes, depending on the style. Some typical applications for these bearings: Hold the (Z-axis) screws in place, supporting and guiding the movements of timing belt systems and reduce turning friction (eg in cold ends).

Flange bearing types are various, according to their size and edges.
