Spherical roller bearing is simple in structure and easy to use. It is a kind of bearing with the largest batch production and the widest range of application. It is mainly used to bear radial load, but also to bear certain axial load. When the radial clearance of the bearing increases, it has the function of angular contact ball bearing, and can bear the axial load of the teaching. Compared with other bearings with the same size, the friction coefficient of this kind of bearing is small and the limit speed is high. When the speed is higher, it is not suitable to use thrust ball bearings, and the bearings can be used to bear axial load.
Specific classification and model control:
1, open spherical roller bearing (type 6000)
Note: it is mainly used to bear radial load, but also to withstand small axial load. Axial displacement of the shaft is limited within the axial clearance, and the inner ring is inclined to.1 - */1 relative to the outer ring
2. Spherical roller bearing (6000 N) with stop grooves in outer ring
Note: the same base type spherical roller bearing is equipped with a stop ring, which can simplify the axial positioning of the bearing in the bore of the bearing seat
3. Spherical roller bearing (6000-ZN) with a dustproof cover on one side and a stop groove on the other side
4. Spherical roller bearing (6000-2ZN type) with both sides dustproof cover and outer ring with stopping groove
5. A spherical roller bearing (6000-Z) with a dust cover
6, spherical roller bearing (6000-2Z) with both sides dust-proof cover
Note: there is a gap between the same base type spherical roller bearing dust cover and inner ring retaining edge, the limit speed is the same as the open spherical roller bearing, the seal is better, the bearing is filled with proper lubricant during assembly, and the cleaning and adding of lubricant are not needed when installing and using.
7, spherical roller bearing (6000-RS, 6000-RZ) with a sealing ring
Note: the seal with the radical spherical roller bearing ring and the inner ring contact flange (post code (% /, /) and non contact (.#, (.#) contact, good sealing effect, but the friction resistance, low speed limit.
8, spherical roller bearing (6000-2RS type, 6000-2RZ type) with sealing ring on both sides
Note: the non-contact sealing speed limit is the same as that of open spherical roller bearing. When the assembly is used, the proper amount of lubricant should be filled into the assembly.
9, flange outer ring spherical roller bearing (F6000 type)
10. A flange outer ring spherical roller bearing (F6000-Z type) with dustproof cover
11. Flange outer ring spherical bearing (F6000-2Z) with both sides dust-proof cover. Roller

Spherical roller bearing is the most widely used and most representative rolling bearing. The raceway of the inner and outer raceway of this kind of bearing is arc shaped deep groove, which can bear radial, axial and composite load. The structure is simple, easy to obtain high precision, suitable for high speed rotation.
Spherical roller bearing usually adopts the steel plate stamping cage, but the size is large, it is not easy to stamping forming or is used for high speed rotation, the turning forming cage is used. Such bearings usually have a dust cap, a sealing ring, a non contact rubber cover, contact rubber cover or stop ring bearing.
