How do I identify my Timken bearings?
To identify: WIDE INNER RING BALL BEARINGS As a general rule, the complete TIMKEN bearing number is either marked on the outside diameter or on the inner ring face (e.g., SM1203K). This number, plus the appropriate suffix letter if applicable, constitutes the full bearing number (e.g., SM 1203KB).
How do you read a bearing part number?
What is a Bearing Number?
- The first number i.e. ‘6’ represents the “type of bearing”.
- The second number i.e. ‘2’ represents the “ bearing series”
- The third and fourth number i.e. “03” represents “bore size”
- And the last two letters i.e. “RS” represents the “Sealing/ Seal”
What do bearing part numbers mean?
The first digit indicates the width or height series (dimensions B, T or H). The second digit identifies the diameter series (dimension D). The last two digits of the basic designation identify the size code of the bearing bore. The size code multiplied by 5 gives the bore diameter (d) in mm.
How are tapered bearings measured?
Taper roller bearings are still measured in the same way, Inside diameter x Outside diameter x Width and are also identified again buy a set of numbers and sometimes letters depending on the manufacturer.
Where are Timken bearings made?
Timken wheel bearings are made in the USA, Mexico, and a number of other countries. The bearings are all made to the same high worldwide standard which Timken is well known for.
Are there fake Timken bearings?
Counterfeit bearings can cost two to three times less than genuine Timken, but the long-term costs far outweigh any short-term savings. Upon receiving the bearing for review, Timken service engineers quickly noticed signs of counterfeiting on both the bearing and packaging.
Are Timken bearings made in China?

What is the meaning of ZZ in bearing?
2 Z / ZZ – Bearing with a metal seal on both sides. Z – Bearing with a metal seal on one side, one side open.
What are bearing numbers?
A bearing number is composed of a basic number and a supplementary code, denoting bearing specifications including bearing type, boundary dimensions, running accuracy, and internal clearance.
How much play should a Timken bearing have?
The key then is to hit the sweet spot between too much end play and not enough. For Timken bearings, this means achieving an end play between . 001 inches and . 005 inches.
Which is part numbering system does Timken use?
Timken tapered roller bearing nomenclature The part-numbering systems for single-row radial tapered roller bearings (type TS) are internationally recognized. Several part-numbering systems have been developed that can be classified according to metric or inch systems.
Is the Timken bearing part number die stamped?
Most Timken symbols are die stamped as part of the bearing number, however there are many cases where our automotive and industrial applications require special considerations in bearing designs and tolerances.

When do you use the term bearing series?
In all the part-numbering systems, the term bearing series is used to describe bearings having the same basic internal geometry (e.g. roller size, inner-ring and outer-ring angles). Any inner ring (including roller set) can be matched with any outer ring within the same series providing that the same type of bearing is being used.
