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.
They usually clearance fit with roll necks to being mounted and dismounted conveniently.
Steel pressed cages are usually used in four-row tapered roller bearings,and pin-type cages are for large-size ones.
Four-row cylindrical roller bearings are the one of the main bearings for rolling mills.
They have compact structures and high stiffness,and can carry high radial loads but not axial loads.
Because of inner rings with no ribs, inner and outer ring subassembly (with full set of rollers and cage) can be mounted respectively. Cleaning, inspecting and dismounting are very convenient.
Four row cylindrical roller bearings are especially applied to rolling mills required high speed and precision, for example,wire mills,bar and shape mills,cold or hot sheet mills and cogging mills.
Brass solid cages or pin-type cages are mainly used in four-row cylindrical roller bearings.
