Decoding TIMKEN 6308
- 63Series
- Deep groove ball bearings, 63 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
6308 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
TIMKEN 6308 measures 40 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (40 x 90 x 23 mm).

A deep groove ball bearing handles radial and axial loads in both directions thanks to its single row of balls running between two rings. Friction stays low and speeds can be high, which is why this design shows up in motors, pumps, fans and many other rotating machines. MR Industrial Accessories LLC supplies Timken deep groove ball bearings to customers in the United States and several Latin American countries.
Reading the code is the first step in picking the right bearing. Three-digit numbers such as 603, 604 and 605 belong to the 600 series and grow in size as the number rises. The 6000 series uses four digits, for example 6000 and 6001. Thin-section or application-specific versions appear under series like 16000 and 61000. Letters added at the end tell you about features: 2RS means seals on both sides, ZZ means shields, and C3 points to internal clearance above normal.
These bearings are common in electric motors, centrifugal pumps, compressors, fans, conveyors and machine tools, as well as in agricultural, food-processing and textile equipment. Their ability to run at high speed while taking combined loads makes them a flexible choice across many plants.
When selecting a bearing, look at the radial and axial load, the rotating speed and the conditions around the machine. Seals keep contaminants out and lubricant in. Shielded versions suit clean areas, while sealed ones handle dirtier settings. Internal clearance should match the operating temperature and the fit. Good alignment and proper lubrication help the bearing reach a long service life, and clean mounting with the right tools avoids damage during installation.
Deep groove ball bearings with the same standard dimensions can be swapped between manufacturers. For a replacement, check the full code including any suffixes so the fit and function stay the same. SKF, NSK, FAG and Timken each list equivalent products under their own naming systems. Our team can help you confirm the correct reference and suggest alternatives when needed, which keeps maintenance simple and cuts downtime.

Frequently asked questions
- TIMKEN 6308 bearing: what are its dimensions?
- TIMKEN 6308 measures 40 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (40 x 90 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6308.
- What do the suffixes in Timken bearing codes mean?
- Suffixes describe specific features: 2RS for rubber seals on both sides, ZZ for metal shields, C3 for internal clearance greater than normal, and others. Include them when you request a replacement so the bearing performs as intended.
- How do I choose between a sealed and a shielded bearing?
- Sealed (2RS) gives more protection against dust and moisture, which suits contaminated environments. Shielded (ZZ) runs with lower friction and works well at high speed in clean areas. The decision depends on operating conditions and maintenance needs.
- Can I replace a bearing from another brand with a Timken one?
- Yes, if the dimensions and tolerances follow the same standard. Deep groove ball bearings are interchangeable between manufacturers. Check the complete code and send it to us on WhatsApp to confirm the exact equivalence.
