Rollon linear guides
Induction hardening for heavy-duty applications
Linear guides in industrial automation and heavy-duty applications are often exposed to high mechanical loads and must meet high requirements in terms of robustness, durability, dynamics and performance.
A high degree of hardness is of crucial importance, as the less hardened the surface of the raceways is, the more susceptible it is to damage. Excessively low hardness depths also have a negative effect on load capacity. For example, rails with thin hardened edge layers tend to crack quickly under load. Induction hardening enables large hardening depths and penetrates into the areas of maximum stresses. The result is a particularly hard and wear-resistant surface. Induction-hardened guide systems can therefore achieve high running performance without damage or deformation of the raceways.
Rollon specializes in the induction hardening of raceways. In induction hardening, the area of the steel to be hardened is first heated inductively, i.e. by means of an electromagnetic field, and then quenched. This causes the structure to undergo a martensitic transformation and, as a result, a considerable increase in hardness. To achieve maximum degrees of hardness, Rollon only uses high-quality steels with a high carbon content. Immediately after induction hardening, the surface can be machined and the surface quality and thus the friction properties can be improved by grinding or honing. The Rollon rails achieve Rockwell hardnesses between 58 and 62 HRC and hardening depths of around 1.2 mm. The induction-hardened and ground raceways are highly resilient, low-maintenance and durable, enabling significant performance improvements in industrial and heavy-duty applications.
