156FC107780A Four-Row Cylindrical Roller Bearings
Overview
It with superior resistance to radial load and very suitable for use at a high-speed.
Because the inner ring raceway surface and the roll can be finished simultaneously after the inner ring is mounted on the roll neck (the inner ring raceway surface is grounded by a roll grinding machine, and then, the roll barrel is finished based on the grounded surface),So the rolling accuracy is improved.
Bore diameter-780 mm; Outside diameter-1070 mm;Width-780 mm; Mass-2140 kg;Cr=24400 kN;C0r=65100 kN
