The primary function is to apply a controlled axial force to eliminate internal clearance in bearing assemblies, thereby increasing stiffness, reducing vibration, and improving positional accuracy in linear motion systems.
Common methods include spring compression, adjustable spacers, tapered wedges, and hydraulic or pneumatic systems. Each method offers different advantages in terms of adjustability, force consistency, and space requirements.
Selection depends on the application's stiffness requirements, load conditions, and desired performance. The preload force range (50–5000 N) is a reference; consult the manufacturer to determine the optimal setting for your specific system.
Regularly check preload force and adjustment accuracy, especially after heavy use or temperature changes. Verify that locking torque is maintained and that no permanent deformation has occurred. Always follow the manufacturer's guidelines for inspection and recalibration.
