Multi-row cylindrical roller bearing SUP BEARING

SUP BEARING multi row have low cross section, high load carrying capacity, stiffness and are used for metal rolling equipment in mills.

They are of separable design that considerably simplifies mounting, maintenance and inspection.

They can tolerate moderate to high shaft speeds. The rollers and outer races are carefully matched to ensure the best load distribution.
Inner rings (designation L) are interchangeable with other assemblies (designation R).
They have cylindrical bore and some sizes are also available with tapered bore. Bearings with tapered bore can be adjusted during mounting to give a certain radial internal clearance or a defined preload

The use of them in metal rolling mills exposes them to very heavy stresses.The rings and rollers can be manufactured with very high quality case hardened carburizing alloy steels. Deep case depth and special heat treatment ensure superior size stability, fracture toughness and reliability.

Where the bearings are mounted with a loose fit on the roll neck, SUP BEARING multi row cylindrical roller bearings have C2 internal radial clearance and are supplied with a helical groove in the bore and/or lubrication grooves in the side faces of the bearing rings for the efficient lubrication (e.g. suffix AC).

SUP BEARING produces the multi row cylindrical roller bearings in several construction.
The various designs differ basically in the number of inner and outer rings, in the number of loose or integral flanges on the outer ring, in the cage type, in the number of rollers in the cage pocket.
Furthermore, on order SUP BEARING can produce the bearings sealed at both sides by radial rubbing seals or with wider inner ring.

They are produced with the normal precision grade for roll neck bearings, conform to class P6 for dimensional and running accuracy to ISO 492.
