Deep Groove Ball Bearings SKF 6202 /C3

The open SKF deep groove ball bearing 6202 /C3 with a 15 mm bore offers increased radial clearance and enhanced P6/P5 precision for demanding speeds.

The SKF 6202/C3 deep groove ball bearing is a single-row radial ball bearing made from standard 100Cr6 rolling bearing steel. As an open rolling bearing without sealing washers, it is suitable for operation in clean environments or oil-lubricated housings. The version in the Explorer performance class combines dimensional accuracy to tolerance class P6 with finer running accuracy to class P5. As a result, the shaft runs with low vibration at high speeds. A robust sheet-steel cage guides the rolling elements across the entire temperature range from -20 to +150 degrees.

What is the 6202/C3 deep groove ball bearing suitable for in practice?

Design engineers prefer to select the 6202 /C3 deep groove ball bearing for applications involving high speeds and thermal influences. Typical applications include high-speed shaft mountings subject to combined loads. Thanks to its open design, lubricating oil or grease reaches the raceways directly, keeping frictional resistance low. As the bearing accommodates radial forces and moderate axial forces on both sides, it functions as a smooth-running fixed or floating bearing in many shaft mountings. A protected housing is required for dusty environments.

What are the advantages of increased bearing clearance (C3) and P5 running accuracy?

The designation C3 indicates a radial bearing clearance that is slightly greater than the standard clearance. This additional radial clearance compensates for thermal expansion caused by heat build-up during operation, as well as dimensional changes resulting from tight fits on the shaft and housing. This helps to prevent the rolling elements from seizing. Together with the increased P5 running accuracy and P6 dimensional accuracy, the bearing ensures precise concentricity with the main dimensions of a 15 mm bore, 35 mm outer diameter and 11 mm width.
