HEGENSCHEIDT MFD: Longer lifetime for bearing rings due hard rolling

News from our sister HEGENSCHEIDT from Erkelenz

Rol­ler bea­rings guide shafts and axles, for exam­ple in vehic­les, indus­trial plants or medi­cal tech­no­logy appli­ca­ti­ons. Usually such bea­rings run per­ma­nently under high loads. Mate­rial fati­gue and lubri­ca­tion defect are the­r­e­fore the main cau­ses of com­po­nent fail­ure. High per­for­mance rol­ler bea­rings can be manu­fac­tu­red with cera­mic ele­ments com­bi­ned with bea­ring steel. For the pro­duc­tion of bea­ring rings, the Fraun­ho­fer Insti­tute for Pro­duc­tion Tech­no­logy IPT Aachen suc­cessfully tes­ted hard rol­ling as a resource-saving alter­na­tive to exten­ding the con­ven­tio­nal pro­cess chain tog­e­ther with three pro­ject part­ners, inclu­ding Hegen­scheidt-MFD GmbH in Erkelenz.

In the three-year rese­arch pro­ject, the Fraun­ho­fer IPT, tog­e­ther with the pro­ject part­ners Cero­bear GmbH, Hegen­scheidt-MFD GmbH and Schmitz-Metall­o­gra­phie GmbH, showed that the bea­ring rings achieve a signi­fi­cantly lon­ger life as a result of the pro­cess sequence of hard tur­ning and hard rol­ling with a newly deve­lo­ped hard rol­ling tool. Hard rol­ling thus offers a resource-saving alter­na­tive to the con­ven­tio­nal pro­cess chain for hard machi­ning, which is also more cost-effec­tive. The lon­ger bea­ring life­time con­tri­bu­tes to a fur­ther increase in effi­ci­ency and the­r­e­fore redu­ces costs not only for manu­fac­tu­rer but also for the operators.
