self-aligning roller bearings 71514172216

Self-aligning Roller Bearings model system is mainly based on series classification, internal structure design, adaptive solutions and special performance to distinguish, the following specific model classification and representative specifications:

First, the core series classification
1. 222 series: covering the inner diameter of 90-400mm, such as 22215CC/W33 (inner diameter of 75mm/outer diameter of 130mm/thickness of 31mm), 22230 (inner diameter of 150mm/outer diameter of 270mm/thickness of 73mm). 73mm).
2. 223 series: ID 90-400mm, typical examples are 22330 (ID 150mm/OD 320mm/thickness 108mm).
3. 230/231 series:
230 series ID 100-1200mm (e.g. 23020CA/W33)
231 series ID 100-750mm (e.g. 23126CE4: ID 130mm/OD 210mm/thickness 64mm). 210mm/Thickness 64mm).
4. 232/239/240/241 series:
232 series ID 90-850mm
239 series ID 170-1200mm
240 series ID 100 -1080mm
241 series ID 100-850mm.
Second, Internal structure code
1.CC type: symmetric roller + stamped steel cage, high load bearing and high speed (such as 22216CA/W33).
2.CA type: symmetrical roller + brass cage, impact resistance (such as 22205 spherical roller bearings).
3.MB type: brass cage optimised version (such as 23020MB/W33).
4.CE type: enhanced load bearing design (such as 23126CE4).
Thirdly. Adaptation programme code
1.K type: conical bore (taper 1:12 or 1:30), need to be fitted with tightening sleeve installation (such as 20000CCK type).
2.K+H type: with tightening sleeve set (such as 20000CCK+H type).
Special Performance Suffix
1./W33: outer ring with oil groove oil holes to optimise lubrication (such as 22214CC/W33).
2./C3: radial clearance greater than the standard group, to adapt to temperature rise deformation.
3./S2: High temperature resistant material, adapt to metallurgy and other high temperature scenes.
Selection Tips
Priority Scenarios: CA/MB for heavy load (mine/mill); CC for high speed and high precision; /W33+S2 combination for high temperature environment.
Alternative: some working conditions can be used spherical ball bearings (such as 1315 type), but the bearing capacity is limited.

Note: Domestic head brand (such as human C&U, Wanxiang Qianchao) has achieved a full range of coverage, technical parameters against international standards.
