The size of the roller bearing is constrained by the space of the rolling mill device (the inner diameter and outer diameter of the bearing depend on the diameter of the roll neck and the roll body); the cross section of the bearing is higher than that of the 粲诒 粲诒 谥岢 欢 欢 腔 匦氤惺 匦氤惺 匦氤惺 匦氤惺 匦氤惺 蟮 蟮蛟 蛟 桑 桑 虼 虼 虼 虼 虼 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢 岢. Most of them use hollow roller and strut cage; in order to improve the smooth condition of the bearing; the outer surface and end face of the bearing are separated from the oil groove and the oil hole; when it is matched with the roll neck; the inner ring of the inner ring of the bearing is spiral-shaped on the outer surface. Oil tank.
Roller bearing layout is based on different types of rolling mills; different working conditions and different layout equipment to determine. In general; four-row cylindrical roller bearings simply achieve higher machining accuracy; therefore, with high speed Rotating characteristics; and because of the convenience of disassembly of the device; and the inner ring raceway surface and the roll surface of the roll can be ground after the inner ring is pressed into the roll neck; it is beneficial to improve the rolling precision; and is used for the support of high-speed and high-precision rolling mills. Roller; four-row tapered roller bearing bearing capacity; can accept radial load and axial load together; suitable for low speed and medium speed rolling mill.
