507518 Four-row cylindrical roller bearings are the one of the main bearings for rolling mills.They mount for interference fit on the roll neck.
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.
