The WITOL® operating principle
Precise tolerance compensation, simplified assembly
The WITOLs’ design allows for a precise and tension-free tolerance compensation between two components. A WITOL consists of four elements:
- Basic element
- Fastening element
- Compensating element
- Spring element
The operating principle
Through rotating the driven screw, tolerances are automatically and simultaneously compensated with the WITOL directly in the screwing process. Thus, a tension-free and reproducible screw connection is produced in a reliable process.
Explained step by step: the WITOL operating principle
The WITOL is pre-assembled on one of the components to be joined. The type of fastening has no influence on the primary function and is derived from the corresponding application.
In the subsequent assembly, the two modules to be screwed together are aligned with each other and brought into their target position. The screw is fed and inserted into the WITOL.
Activate tolerance compensation
The WITOL is activated by rotating the screw and automatically compensates the distances between the components.
WITOL tolerance compensation
As soon as the WITOL reaches the counter position, the compensation process is completed.
The screw is fixed with the desired tightening torque and the preload force is introduced into the system. The result is a pre-tensioned and at the same time tension-free screw connection.
