What are the dimensions of this ball bearing?

The bore diameter is 25 mm, the outer diameter is 62 mm, and the width is 17 mm.

What does the 2Z designation mean?

The 2Z suffix indicates that the bearing has non-contact metal shields on both sides.

What is the purpose of the C3 radial internal clearance?

The C3 clearance is greater than standard, accommodating thermal expansion at high speeds or operating temperatures.

What type of bore does the SKF 6305-2Z/C3 have?

It features a standard cylindrical bore of 25 mm for direct mounting on a straight shaft.

Does this bearing require lubrication before use?

No, this double-shielded bearing is factory pre-lubricated with grease for maintenance-free operation.

Smooth performance by Skf

Practical benefits

Dual metal shields: You keep contaminants out and retain internal lubrication efficiently with non-contact steel shields on both sides.
Extended C3 clearance: You accommodate thermal expansion reliably during high-speed operation and demanding rotational workloads.
Versatile load capacity: You handle radial and axial forces effectively in both directions while maintaining low friction and minimal vibration.

In a nutshell

The right choise for

With the Skf 6305-2Z/C3 deep groove ball bearing, you keep your rotating machinery running smoothly and reliably. Featuring a 25 mm cylindrical bore, 62 mm outer diameter, and 17 mm width, this single-row steel bearing accommodates both radial and axial loads with minimal friction. Its increased C3 internal clearance reliably compensates for thermal expansion during high-speed operation in electric motors, pumps, and gearboxes. Dual metal shields keep the factory-applied lubricant securely inside while effectively locking out dust and dirt.

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
