What are the dimensions of this SKF ball bearing?

This ball bearing has a 40 mm bore diameter, a 90 mm outer diameter, and a width of 23 mm.

What does the C4 clearance rating mean?

C4 denotes a radial internal clearance greater than standard (and greater than C3), ideal for high thermal expansion or tight fits.

Is this SKF 6308/C4 bearing sealed?

No, this is an open bearing without seals, designed for external lubrication in a clean housing or system.

What bore type does this deep groove ball bearing have?

It features a cylindrical bore, fitting directly onto a standard 40 mm straight shaft.

What loads can this single row deep groove ball bearing accommodate?

It accommodates radial loads as well as axial loads in both directions.

Smooth rotation with Skf 6308/C4

Practical benefits

Increased internal radial clearance: The C4 clearance accommodates thermal expansion, allowing you to run machinery at elevated operating speeds without risking premature seizure.
Combined dual load support: You handle both radial and axial forces in either direction thanks to the deep groove track geometry.
Low friction for durability: The open steel construction minimizes rotational resistance and heat generation, helping you maximize service life and overall efficiency.
