Split Roller Bearings

Split bearing unit is designed for continuous casters. The centre bearing of the drive roller in continuous casting machines can be equipped with split bearing unit from our product. Split cylindrical roller bearings run inside a water-cooled housing. Compared with the normal version, the split inner race of the bearing is slightly broader so that the race halves can be preloaded.With the design adapted to the actual load, the working load that affects only the lower section of the housing is absorbed by a hardened outer ring half. This solution has the added advantage that the space thus gained can be used for cooling in the bearing cover. The inlet and outlet for the cooling water are at the foot of the housing. Practice has shown that this ensure adequate cooling so that the bearings do not overheat and they can be lubriated with normal roller bearing grease.Since this application involves considerable quantities of splashing water, steam and scale, careful sealing of the bearing and its surroundings is crucial. Effective sealing can be achieved by using lamellar rings close to the roller bearings and installing labyrinths between the seal support and the drive roller. We produce bearing units for wide range of diameters according to client demand.
