Miniature Flanged Bearings-Flanged Bearings-Ktaiballbearing

Miniature Flanged Bearings include metric flanged bearings, inch flanged bearings and extended inner flanged bearings.

Metric miniature flanged bearings have bore size as small as 1mm.
Inch miniature flanged bearings and Extended inner miniature flanged bearings have bore size as small as 0.0469″.

The construction of miniature flanged bearings can carry moderate radial and thrust loads at low operating torque and provide high performance, and they are sometimes referred to as instrument bearings or micro bearings.
