Deep Groove Ball Bearings SKF 6203 -2Z

The SKF 6203-2Z deep groove ball bearing, with a 17 mm bore, sheet metal end shields on both sides and P6/P5 tolerances, ensures smooth running for compact shaft mountings.

The 6203-2Z deep groove ball bearing is a single-row radial ball bearing made from standard roller bearing steel by SKF, in the Explorer performance class. With a bore of 17 mm, an outside diameter of 40 mm and a width of 12 mm, this rolling bearing primarily accommodates radial forces as well as moderate axial forces. The cover plates on both sides protect the interior from dirt particles, whilst the integrated sheet steel cage guides the rolling elements evenly. Thanks to its standard radial clearance, the component is suitable for operating temperatures ranging from -20 to +120 degrees Celsius.

What is the 6203-2Z deep-groove ball bearing suitable for?

This deep-groove ball bearing is suitable for designs with limited installation space that are subject to predominantly radial loads and medium to high speeds. As the non-contacting sheet metal end shields do not cause any additional friction at the sealing lips, heat build-up during operation remains low. The design functions as a fixed or floating bearing in clean to moderately dusty installation environments without direct exposure to liquids.

What are the advantages of cover plates and tolerance class P6/P5?

The sheet metal covers on both sides keep out solid foreign matter and retain the lubricant inside the bearing. As these are non-contact gap seals, temperature rise during operation remains low. This model combines dimensional accuracy to P6 with finer running accuracy to P5. This reduces radial runout compared with conventional standard bearings. Design engineers and maintenance personnel choose this specification when assemblies need to rotate with low vibration and precise concentricity on the 17 mm shaft is required.
