Tolerance Compensation Systems, Stepless

Bollhoff Fastenings Pvt Ltd offers Flexitol®, stepless Tolerance Compensation Systems for highly automated assembly industries like automotive. The supplier industry mainly provides assemblies and the automobile manufacturing plant then only has to carry out the final assembly. In the so-called modular construction, standardised parts are assembled to complete systems (modular design principle). As part of the corresponding development process, appropriate tolerances have to be defined so as to be able to implement series production. High demands on the producer and customer sides regarding reliable functioning and first class quality such as small gap widths require economic assembly solutions with tolerance compensation. Flexitol automatic tolerance compensation system provides a technically and economically optimised solution. A tolerance compensation element consists of at least two components – an adjustment element and a fastening element. First of all, the tolerance compensation element is installed in the receiving part. There are different installation methods. The assembly to be installed is brought into the desired assembly position. Upon screwing, compensation distance between receiving part and mounting part is steplessly and automatically compensated. The friction element serves-to move the adjustment element. The adjustment element is connected to the fastening element via a left-hand thread. By screwing in the screw clockwise, the adjustment element drives out until touching the mounting part. Afterwards, the screw is further screwed in until the entire assembly is secured by screw preload force. Currently, there are three Flexitol types: Flexitol metal; Flexitol hybrid; Flexitol plastic. Different areas of application mean different demands and therefore require application optimised tolerance compensation systems.
