Tapered Roller Bearing Numbering System Chart | Complete Guide for Industrial Buyers
At [Your Brand Name], we empower industrial buyers across North America and Southeast Asia with precision-engineered tapered roller bearings supported by our regional warehousing network. When a manufacturing plant in Vietnam urgently needed to replace failed bearings last monsoon season, our localized inventory and numbering system expertise kept their assembly line running.
Critical Pain Points in Bearing Identification
Procurement teams frequently encounter these challenges with tapered roller bearing numbering systems:
- Inconsistent standards between ISO, ABMA, and manufacturer-specific codes
- Metric/imperial confusion causing 23% of wrong orders (Bearing Industry Survey 2023)
- Obsolete part numbers in aging machinery documentation
Technical Parameters Comparison
Prefix/Suffix | Meaning | Example |

HH | Heavy duty | HH224334 |
J | Tapered bore | 32208J |
Quality Assurance Protocol
Our bearings undergo:
- 100% dimensional verification per ISO 492:2014
- Raceway hardness testing (60-64 HRC)
- Vibration analysis with SKF Microlog AX
Regional Case Studies
Thai Automotive Tier-1 Supplier: Reduced bearing failures by 68% after implementing our numbering system cross-reference tool for their Kawasaki production line.
Procurement Decision Q&A
Q: How do I identify interchangeable bearings across brands?
A: Match the last 3-4 digits indicating bore size and series, then verify load ratings.
Q: What does 'K' suffix mean in Timken numbering?
A: Indicates tapered bore (1:12 ratio) per ANSI/ABMA Std 19.1
