Decoding SKF 6408 N
- 64Series
- Deep groove ball bearings, 64 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- NSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6408 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 6408 N measures 40 mm across the bore and 110 mm across the outside diameter; its width is 27 mm (40 x 110 x 27 mm).

When a housing has no shoulder or cover to hold the outer ring, an SKF deep groove ball bearing with a machined groove on its outer ring can be secured axially with a snap ring. These single-row bearings simplify housing machining and speed up assembly. MR Industrial Accessories supplies this line and helps you match the right variant to your equipment.
The part number tells you the construction. In codes such as 6006 N, 6205 N or 6308 N, the first digits set the dimensional series: 60 is extra-light, 62 is medium section and 63 is the heaviest. The N suffix means the outer ring carries a groove for a snap ring. Other series and codes exist, so always read the full designation.
You will find these bearings in electric motors, centrifugal pumps, fans, gearboxes and conveyors. Common settings include packaging lines, refrigeration units, machine tools and food plant drives. The groove replaces a machined housing shoulder: a snap ring locks the outer ring and takes moderate axial loads.
Selection depends on internal clearance, sealing and lubrication. In dusty or damp areas, consider sealed or shielded versions. Shaft and housing alignment matters, because misalignment reduces bearing life. At assembly, check that the snap ring sits fully in the groove and that the outer ring can still expand.
Brand interchange works through the designation system: a series 62 bearing with groove from one maker can be replaced by an equivalent from another when dimensions, clearance and execution match. The series number alone is not enough; compare tolerances, cage type and lubricant. If in doubt, send the complete code and housing dimensions.
MR Industrial Accessories works with SKF bearings and other power transmission lines. To replace a grooved bearing, send the code engraved on the ring, the equipment brand and a photo of the assembly. With that, we quote the right variant via WhatsApp and advise on the compatible snap ring.

Frequently asked questions
- SKF 6408 N bearing: what are its dimensions?
- SKF 6408 N measures 40 mm across the bore and 110 mm across the outside diameter; its width is 27 mm (40 x 110 x 27 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6408.
- What does the N suffix mean on a deep groove ball bearing?
- It means the outer ring has a machined groove for a snap ring. That ring holds the bearing axially in the housing. Main dimensions and load capacity stay the same.
- How do I request a quote for an SKF bearing with groove?
- Send the full code from the ring, for example 6205 N, plus the equipment brand and model via WhatsApp. If you do not have the code, send shaft and housing dimensions.
- Can I use a bearing without groove in place of a grooved one?
- Only if the housing has another way to fix the outer ring axially. Without the groove, the snap ring cannot be mounted. Send us the housing details and we will review the options.
