NTN ASFB204 Flange Bearing Unit

The NTN ASFB204 Flange Bearing Unit is a light rhombus flange bearing unit designed for reliable shaft support in industrial machinery and equipment. It features a cast housing, two-bolt flange and set screw locking for secure shaft mounting.

The ASFB204 is designed for a 20 mm shaft diameter and uses an M8 mounting bolt. It has a 90 mm overall length, 71.5 mm mounting dimension and 61 mm flange length. The compact rhombus flange design provides secure mounting while requiring less space than larger flange arrangements. The set screw locking system helps secure the bearing to the shaft.

The ASFB204 is a maintenance-free type, as it does not have the D1 relubrication suffix. It is suitable for industrial machinery, conveyors and other equipment requiring compact and reliable shaft support.
