SKF 6205 C3 Deep Groove Ball Bearing 25x52x15 mm

AI Overview

The SKF 6205 C3 is a premium single-row deep groove ball bearing designed for high reliability, low friction and long service life. With dimensions of 25x52x15 mm, it is one of the world's most widely used bearing sizes for electric motors, pumps, gearboxes, fans, conveyors and industrial machinery.

The C3 internal clearance provides greater radial clearance than standard bearings, making it ideal for applications operating at elevated temperatures or high rotational speeds where thermal expansion occurs. The SKF Explorer design delivers outstanding durability, reduced friction and increased bearing life.

FAQ

What does C3 mean?

C3 indicates greater-than-normal internal radial clearance, allowing the bearing to compensate for thermal expansion and operate reliably at higher temperatures and rotational speeds.

What type of bearing is SKF 6205 C3?

It is a single-row deep groove ball bearing capable of supporting both radial and axial loads.

Is this an open bearing?

Yes. The standard SKF 6205 C3 is an open bearing without seals or shields and requires external lubrication.

Where is SKF 6205 C3 commonly used?

It is widely used in electric motors, pumps, compressors, gearboxes, fans, conveyors and many industrial machines.

Why choose SKF Explorer bearings?

SKF Explorer bearings offer lower friction, improved load capacity, longer service life and higher reliability compared with conventional bearings.
