Higher Operational Reliability Through Innovative Solutions

Increasingly complex bearing requirements make it necessary to blaze new trails. Through continuous product support and development, Schaeffler Group Industrial is able to meet new challenges by offering functionally reliable and efficient solutions. Hybrid Deep groove ball bearings Hybrid ball bearings with steel rings and ceramic balls have proven effective for spreader rolls with high speeds. To reduce the amount of rotating masses (ball and cage assembly), only half the number of balls are installed. The risk of slip decreases as a result of the higher load on each ceramic ball. Compared to the conventional steel-steel design, the operating life is two to three times longer.

Self-aligning cylindrical Roller bearings When drying cylinders are heated, the long cylinders expand lengthwise significantly. In addition, misalignment occurs between the two bearing positions. The solution: Self-aligning Cylindrical roller bearings. They are most often used in the dry end and frequently replace the previous solution that involved rocker block housings. These housings can still be used, while length changes are easily compensated in the bearing. The spherical sliding surface of a self-aligning plain bearing ring compensates potential deflections or alignment inaccuracies of the cylinder journals.
