Maintenance-free bearings in confined installation space in rolling machine for lorry mudguards

This rolling machine processes aluminium profiles for the automotive industry. The end product is used as mudguards for trailer and lorry wheels. Plain bearings are used in the pressure roller lifting system. The system used to use steel bearings, but they required a great deal of maintenance. They had to be lubricated regularly and were not precise enough. The linear bearings in the machine for raising and lowering the roller were also to be replaced. Special challenges were the limited installation space available in the system for the components and large amounts of dust. In the old system, dust settled on the lubricants, making regular maintenance necessary.

By combining drylin W single rails as linear bearings and flanged iglidur Z plain bearings, the company found a solution to all questions and concerns.
The main problem of the previous application was the steel linear technology. The linear plain bearings from the drylin range (WSQ-10, WWC-10-40-10) operate without lubricants and require no maintenance. They are therefore not only insensitive to the large amounts of dust in the system, but also work with greater precision. As damage to the products is avoided, product quality is improved. The plain bearings from the iglidur range (ZFI-2831-32) also work without maintenance and eliminate the clearance of the previous steel bearings.
