Cylindrical Roller Bearing 527247 For High speed Cable Wire Stranding Machine

precision cylindrical roller bearing 527247 for cable wire stranding machine

Single row cylindrical roller bearing 527247  with cage are units comprising solid inner and outer rings and cylindrical roller and cage assemblies. They will need to lathe process, heat treatment process and grinding process to finish them.All the process will be self check and monitoring. The outer rings have rigid ribs on both sides or no ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling.The heat treatment will be need HRC58-62.

cylindrical roller bearing 527247  the data as following:

Single-row cylindrical roller bearings are separable bearings,the rollers are guided by the two ribs of bearing rings.The cage,rollers and guide ring are assembled to a unit, and can be separated from the other ring. These bearings are easy to be mounted and dismounted,especially inner and outer rings interference fit with shafts and housings.
The structures of cylindrical roller bearings are distinguished by ribs.Type N has inner ring with two ribs and outer ring without rib;type NU has outer ring with two ribs and inner ring without rib; type NJ has inner ring with rib and outer ring with two ribs, and can carry certain axial loads in one direction;type NF has inner ring with two ribs and outer ring with rib.
The machining accuracy of shafts and housings which is fitted with single-row cylindrical bearings is high, the obliquity is forbidden between inner and outer ring axises. If the inner and outer ring axises were oblique,the contact between rollers and rings will be asymmetric, and the stress will be intensive, then it will have serious effects on bearing loading capacity and life.The edge effect between rollers and raceways will be down,and bearing life will be prolonged if there was some convexity on inner and outer raceways or roller generatrix.
The axial displacement of shafts or housings can’t be limited by cylindrical roller bearings. If it was needed, they are often used with other bearings,such as deep groove ball bearings.

This type of bearings generally carry radial loads,but bearings with ribs on inner and outer rings can carry certain axial loads.
It is not permitted that the obliquity between shafts and housings,but 2′angular misalignment between inner and outer ring axises is permitted under lower loads.If the loads were higher, the more angular misalignment will be permitted, but the upper limit is 4′.
When D≤400mm, steel pressed cages are commonly used,and steel or brass solid cages are adopted for D>400mm.

We/JinHang precision bearing orrer radial cylindrical roller bearings can offer higher radial load capacity than other bearing designs. The offers a wide range of full complement, one -, two -, and four-row designs to meet various application requirements.
cylindrical roller bearings consist of an inner and outer ring, a roller-retaining cage, and a complement of controlled- contour cylindrical rollers. Depending on the type of bearing, either the inner or the outer ring has two roller-guiding ribs. The other ring is separable from the assembly and has one rib or none. The ring with two ribs axially locates the position of the roller assembly. The ground diameters of these ribs may be used to support the roller cage. One of the ribs may be used to carry light thrust loads when an opposing rib is provided. The decision as to which ring should be double ribbed is normally determined by considering assembly and mounting procedures in the application.
