Product Description
26DC30160DS is a standard universal three-row cylindrical roller backing bearing belonging to the DC series, with precise overall dimensions of inner diameter 130mm, outer diameter 300mm, width 160mm and a net weight of 64.8kg. It supports JTEKT original interchange standards and is a core supporting component specially developed for ZR22 multi-roll cold rolling mills and 20-high Sendzimir precision rolling mills.
This heavy-duty backing bearing has a dynamic load rating (Cr) of 1660kN and a static load rating (Cor) of 2340kN, with a fatigue limit load of 297kN. It adopts high-quality bearing steel and precision machined brass cage, equipped with extra-thick reinforced outer ring structure to greatly enhance bearing rigidity and impact resistance. The standard configuration of CN normal clearance (optional C2 small clearance) and open unsealed design ensures low friction operation and high rolling accuracy.
The bearing supports multiple precision grades including P0, P6, P5 and P4, with a working temperature range of -30℃ to 120℃, featuring stable performance, low vibration and long service life. It is widely used in precision thin strip rolling, stainless steel processing, sheet straightening and other heavy-duty metallurgical equipment, suitable for long-term continuous heavy-load and high-precision rolling production scenarios.
