7、er 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 beari
8、ngs 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/P25) for the bearings to run well in succession. Otherwise wear may happen when lubrication is running out or rotating speed is high. N
9、CFV 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 cas
10、e. For this “s” value, please consult SBI technical service. NJV 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 di
11、smantling of the type of bearings are convenient. The bearings can carry axial load in one direction. NNF2LSNVY type double-row full complement cylindrical roller bearings are with two inseparable inner rings joined by a holding ring. There is a rib in middle of the outer ring. The bearings can carr
12、y axial load in both directions and be used as stationary bearings. As the distance between the two rows of rollers is big, the bearings can also take some overturning moment. On the outer ring there are two snap grooves for axial orientation. This type of bearings is with contact seals on both side
13、s and with lithium based grease. The operating temperature limit for the bearings is from 40 to 80 . The kind of bearings is generally free of maintenance under some certain conditions,. But in case that there is vapor or dust, and the bearings are running in medium or high speed, supplement lubrica
14、nt is absolutely necessary. If using rare oil as lubricant, the seals should be removed and all the grease within the bearings be washed out. In that case, the limit rotating speed can be increased 30%. The dimension tolerance and geometry deviation of the type of bearings are in accordance with Gra
15、de P0 of GB 307.1-1994(ISO 492-1994). And the normal radial clearance is with group C0. Bearings with normal radial clearance of Group C2 or C4 are also available. In that case some suffix should be added to the bearing code. For example, bearings with group C3 are generally selected for the plastic
16、 extruders. If you have requirement for higher grade bearings, please contact SBI service. For mounting tolerance, you can refer to the selection principle of housing tolerance and shaft tolerance limits. Some certain axial loads are allowed for the type of bearings. In that case, sufficient lubrica
17、tion is a premise. In the single direction stationary bearings and stationary bearings, the rib that carrying axial load must be fully supported. Attention: when mounting and dismantling the cylindrical roller bearings, the force should not be transmitted directly through the cylindrical rollers and
