What are the dimensions of this ball bearing?

This bearing has an inside diameter of 90 mm, an outside diameter of 190 mm, and a width of 43 mm.

What does the 2Z designation mean?

The 2Z suffix means the bearing is fitted with non-contact metal dust shields on both sides.

What does the C3 radial clearance mean?

C3 indicates a greater internal radial clearance than normal, suitable for high speeds or thermal expansion.

What loads can this deep groove ball bearing handle?

It accommodates radial loads and axial loads in both directions.

What type of bore does this SKF bearing have?

This bearing has a cylindrical bore designed for a standard 90 mm shaft.

Reliable rotation with Skf bearing

Practical benefits

Protection from contaminants: Double metal shields keep lubricant inside while blocking dust and dirt, extending your bearing service life.
Increased C3 clearance: You prevent friction build-up when components expand due to thermal growth with built-in C3 radial clearance.
Combined load capacity: This unit supports radial and axial loads in both directions to keep your machinery running smoothly.

In a nutshell

The right choise for

With the Skf 6318-2Z/C3 deep groove ball bearing, you keep industrial electric motors, pumps, and drive shafts running smoothly and reliably. This single-row steel bearing with a 90 mm cylindrical bore easily accommodates combined radial and axial loads in both directions. Thanks to the increased C3 internal radial clearance, you prevent bearing seizure caused by thermal expansion and elevated operating temperatures. The double metal shields keep factory lubricant securely inside while blocking dust and debris, ensuring an extended service life without frequent maintenance requirements.

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
