(spherical roller bearing number)
Modern spherical roller bearing number
s follow standardized identification systems that encode critical technical parameters. The ISO 15:2017 standard specifies that a complete bearing designation typically contains:
For example, 22324 CCJA/W33 breaks down as:
22 = Extra width series
3 = Medium diameter series
24 = 120mm bore
CC = Two window steel cage
JA = Machined brass cage
W33 = Lubrication groove
Bearing Type | Dynamic Load (kN) | Speed Limit (rpm) | Temperature Range |
---|---|---|---|
Spherical 22216 | 325 | 3400 | -30°C~200°C |
Cylindrical NU206 | 265 | 9500 | -40°C~150°C |
Tapered 30206 | 198 | 6000 | -30°C~120°C |
Leading manufacturers demonstrate distinct technical profiles:
Vendor | Production Capacity | Lead Time | Certifications |
---|---|---|---|
SKF | 2M units/month | 6-8 weeks | ISO 9001:2015 |
NTN | 1.5M units/month | 8-10 weeks | AS9100D |
Timken | 1.2M units/month | 10-12 weeks | IATF 16949 |
Specialized bearing modifications address specific operational requirements:
Recent project specifications required spherical roller bearings with 320°C operational capability through special heat stabilization processes (M50 steel, modified quenching).
Heavy-duty applications demand precise bearing selection:
Industry | Bearing Type | Failure Rate Reduction |
---|---|---|
Mining | 223 Series | 62% |
Wind Power | 240/500 CA | 78% |
Steel Mills | 231/710 MB | 55% |

(spherical roller bearing number)
A: Spherical roller bearing numbers follow ISO standards like 222/500 CAK/C3. The numbering indicates dimensions, clearance, and cage type. Check manufacturer size charts in PDFs for exact measurements.
A: No – cylindrical (e.g., NU1008) and tapered (e.g., 30206) bearings use distinct numbering systems. Always verify codes against separate size charts in PDF documentation.
A: Major manufacturers like SKF, Timken, or NSK provide free PDF catalogs online. Search "[Brand] cylindrical roller bearing number and size chart PDF" for precise bore/diameter data.
A: Yes – codes like 32956X/J2QA denote contact angles through suffixes. Cross-reference numbers with PDF charts to confirm angle, width, and load ratings.
A: Suffixes indicate features: CCJA = two-piece brass cage, W33 = grease groove. Consult the "designation key" section in manufacturer PDF charts for full code explanations.
