Sendimir Bearings: Precision-rolled heavy-duty support cores

Sendzimir bearings, also known as Sendzimir bearings, are specially customized for the back-up rolls of multi-roller cold rolling mills (such as twenty-high and eighteen-high rolling mills). With their unique structure and excellent performance, they have become a key component in the field of precision rolling of steel and non-ferrous metal sheets, and are the core support to ensure high-precision and high-quality production of plates.

From a structural point of view, Sendimir bearings are special cylindrical roller bearings, usually consisting of an outer ring, an inner ring, cylindrical rollers and a cage, with a common three-row or double-row roller layout. The core design highlights are the "thick-walled outer ring" and "high-precision fit": the wall thickness of the outer ring is 4-8 times that of the inner ring, and is directly used as the roller surface, eliminating the need for a roll shaft, simplifying the structure and enhancing load-bearing rigidity; the rollers and the inner and outer ring raceways are super-precision ground, and the matching accuracy is extremely high. The cross-section H values of the same group of bearings do not differ by more than 0.005mm, and the H values of adjacent bearings are controlled within 0.002mm to ensure smooth operation. The cage is mostly made of brass and is precision machined to effectively separate the rollers, reduce friction and collision, and ensure stable operation of the rollers under high speed and heavy load.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
