Four-row tapered roller bearings are the one kind of roll neck bearings,their radial and axial loading capacity are high,can carry heavy axial loads in two directions,and their radial loading capacity is 3 times heavier than singe-row tapered roller bearings, but limiting speed is lower.They can be used as axial locating bearings in two directions because they are able to limit axial displacement in two directions within axial clearance. The radial and axial clearance also can be adjusted by changing the width of spacer between inner and outer rings.
Four-row tapered roller bearings are mainly used in the working roll necks of hot or cold rolling mills, and roll neck of cogging mills.
The application:
Such as :Continuous Casting, Converter Gear Box,Mill roller,
Flying shear, Pinch Pass MIll, Shears, Hoisting Machine,etc.
Case:Bearing for 650 850 950 1100 hot strip rolling mills, Bearings for 1450,1500,1550,1580 ,
1700, 1750,1780 rolling mills,Bearings for 1780 Stainless Steel Hot Rolling mills and Cold rolling mills,
Bearings for Channel Type steel Rolling Mills, Bearings for Continous Casting,
Bearings for Flying Shear of Hot Rolling Mills,Bearings for Tilting Equipment for Converters,Bearing for
Converter Trunnion and so on.
