What are the dimensions of this SKF ball bearing?

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

What does the 2Z designation mean?

The 2Z suffix indicates non-contact metal shields on both sides to keep contaminants out.

Why choose a bearing with C3 radial clearance?

C3 internal clearance is greater than standard, accommodating thermal expansion at higher operating speeds.

Which load types does this bearing accommodate?

This single-row deep groove ball bearing supports both radial and axial loads in both directions.

Does this bearing require lubrication before installation?

No, it comes pre-greased from the factory and requires no regular relubrication.

Smooth operation with the 6308-2Z/C3

Practical benefits

Increased clearance under thermal expansion: The internal C3 clearance ensures you maintain seamless rotation even when operating temperatures cause components to expand.
Dual metal shields retain lubrication: Built-in metal shields protect the internal rolling elements from debris while keeping essential grease securely inside.
Robust support for heavy loads: You reliably handle combined radial and axial stresses across demanding machinery setups with this durable steel bearing.

In a nutshell

The right choise for

Keep your rotating machinery shafts running smoothly and reliably with the Skf 6308-2Z/C3 single-row deep groove ball bearing. Engineered from durable steel with a 40 mm cylindrical bore, it easily accommodates both radial and axial loads. The increased C3 internal radial clearance prevents binding during thermal expansion, making it ideal for electric motors, pumps, and industrial gearboxes. Featuring dual metal shields, this bearing keeps dust and debris out while sealing factory lubrication inside, ensuring low-maintenance operation and dependable performance.

Product description

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.

Integral sealing prolongs bearing service life
Simple, versatile and robust design
Low friction and high-speed capability
Accommodate radial and axial loads in both directions
Require little maintenance
