The 48290DW.220.220D or 509680 four row tapered roller bearing details as follows:
|
Component |
Two double cones, two single cups and a double cup with a cone spacer and two cup spacers. Spacers have slots or holes for lubrication. Cone are hardened to reduce face wear.spacers Numbered serially to assure correct installation sequence. |
|
Details |
TQO bearings are directly mounted and comprised of two double inner races, two single and one double outer race, with an inner race spacer and two outer race spacers. Slots in the inner race spacer permit lubricant to flow from the bearing chamber to the roll neck. The inner race spacers are hardened to minimize face wear. |
|
Application |
heavy plate mills _ hot strip mills _ cold rolling mills _ skin pass mills _ roughing mills _ universal beam mills _ rod, bar and wire mills |

Four row tapered roller bearing are the one kind of roll neck bearing,their radial and axial loading capacity are high,can carry heavy axial loads in two direction,and their radial loading capacity is 3 times heavier than signle row tapered roller bearing, but limiting speed is lower.They can be used as axial loacating bearing in two direction because they are able to limit axial displacement in two direction within axial clearance.The radial and axial clearance also can be adjusted by changing the width of sapcer betwwen inner and outer rings.
