How to Read a Timken Bearing Number
Timken uses two designation systems. Metric bearings follow the ISO standard — multiply the last two digits by 5 for bore diameter (special codes: 00=10mm, 01=12mm, 02=15mm, 03=17mm). Inch tapered roller bearings use Timken's own system with a duty-class prefix, angularity digit, and separate part numbers for the cone (inner ring + rollers + cage) and cup (outer ring). Suffixes are separated by spaces or dots.
