Cylindrical roller bearing NNCF series

radialaxialdouble-row

SBI full complement cylindrical roller bearings (Full Complement Bearings) are designed to carry heavy load. Comparing with traditional bearings with cage, full complement cylindrical bearings have much higher loading capacity. The radial cross section of the type of bearings is very small. So it can be very space – saving. However the limiting speed of the bearings is relatively lower. All the multi – row cylindrical roller bearings are with a lubrication groove and one nipple on the outer ring. A minimal load is required (C/P <25) for the bearings to run well in succession. Otherwise wear may happen when lubrication is running out or rotating speed is high. NCF•••V type full complement cylindrical roller bearings are with a single rib on one side of the outer ring. A snap ring is on the other side which makes the shaft be stationary in single direction. The axial gap “s” inside the bearings ensures the axial displacement of shaft to the bearing housing case. For this “s” value, please consult SBI technical service. NJ•••V type full complement cylindrical roller bearings is applied under very high loads and slow rotating speed conditions. The rollers are self – locked and will not fall apart even if the inner ring is removed. Therefore, the mounting and dismantling of the type of bearings are convenient. The bearings can carry axial load in one direction.
