Deep Groove Ball Bearings FAG 6003 -2RSR-C3

The 6003 -2RSR-C3 deep groove ball bearing from FAG Wälzlager, with dimensions of 17x35x10 mm, C3 clearance and a ground seal on both sides, offers reliable protection against dirt.

This single-row deep-groove ball bearing 6003 -2RSR-C3 from FAG Wälzlager primarily accommodates radial forces as well as axial loads in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel with a sheet steel cage, this compact unit – with a bore of 17 mm, an outside diameter of 35 mm and a width of 10 mm – covers a wide range of applications. The sliding seals on both sides protect the interior of the bearing from contamination and help retain the lubricant within the operating temperature range of -20 to +100 degrees.

What loads can the 6003-2RSR-C3 deep-groove ball bearing accommodate?

The design is suitable for bearing locations requiring radial guidance and capable of withstanding moderate axial loads in both directions. Thanks to the RSR contact seals on both sides, this version is designed for environments subject to dust or splashing water. Depending on the installation concept, the bearing can be used as a fixed or floating bearing. The integrated sheet steel cage guides the rolling elements with low vibration whilst ensuring even load distribution across the entire raceway.

What is the function of the C3 bearing clearance and the 2RSR seal in the 6003?

The C3 designation indicates a slightly increased radial bearing clearance compared with the standard version. This increased clearance compensates for operational thermal expansion of the shaft and housing, as well as fit allowances during installation, without the bearing becoming stressed. The sliding 2RSR seal lips rest against the inner ring, which helps to prevent the ingress of foreign particles. When designing the system, bear in mind that the friction caused by sliding seals is slightly higher than that of non-contact cover plates.
