What are the dimensions of this SKF deep groove ball bearing?

This ball bearing has an inside diameter of 50 mm, an outside diameter of 110 mm, and a width of 27 mm.

What does the 2Z designation mean?

The 2Z suffix means the bearing is equipped with non-contact metal shields on both sides to keep contaminants out.

What does the C3 internal clearance indicate?

C3 indicates a radial internal clearance greater than normal, ideal for high operating speeds and thermal expansion.

What types of loads can this bearing accommodate?

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

Does this bearing require lubrication before installation?

No, the bearing comes pre-lubricated from the factory and is virtually maintenance-free due to its protective shields.

Smooth rotation under demanding conditions

Practical benefits

Effective protection against debris: The dual metal shields help you keep contaminants out while retaining lubricant inside the bearing assembly.
Greater C3 internal clearance: An expanded C3 radial clearance ensures you avoid binding during thermal expansion and high-speed operation.
Reliable combined load capacity: With the 6310-2Z/C3 deep groove ball bearing, you easily support both radial and axial loads in both directions.

In a nutshell

The right choise for

With the Skf 6310-2Z/C3 single-row deep groove ball bearing, you keep electric motors, pumps, and industrial drives running smoothly. Dual metal shields effectively keep out dust and debris while retaining factory lubrication for virtually maintenance-free operation. Thanks to the expanded C3 radial internal clearance, you prevent binding caused by high rotational speeds and thermal expansion of the shaft or housing. Measuring 50X110X27 mm, this robust steel bearing reliably accommodates combined radial and axial loads in both directions.

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
