A spindle journal is the cylindrical end section of a threaded spindle, which is inserted into bearings or mounting bores to precisely guide the spindle and accommodate rotational movements. It facilitates power transmission between the spindle and the bearing or housing, ensuring correct axial positioning.
The spindle journal therefore ensures:
- Securing spindle alignment in bearings
- Accommodation of radial and axial forces
- Enables precise rotational movements and reduces wear
Technical Application
- Used in fixed and floating bearings
- Connection of the spindle to housings or motors
- Part of the mechanical guidance and stabilization of long spindles
