Deep Groove Ball Bearings SKF 6204 -2Z/C3

The SKF 6204 -2Z/C3 deep groove ball bearing, with dimensions of 20x47x14 mm, sheet metal end shields on both sides and a C3 clearance, offers a robust solution for rotating shafts.

The SKF 6204 -2Z/C3 single-row deep groove ball bearing primarily absorbs radial forces whilst also supporting axial loads in both directions. With a 20 mm bore, an outer diameter of 47 mm and a width of 14 mm, this rolling bearing complies with established dimensions in mechanical engineering. The outer ring, inner ring and rolling elements are made of standard roller bearing steel (100Cr6). A sheet steel cage guides the balls evenly into the deep raceways.

What operating conditions does the 6204-2Z/C3 deep-groove ball bearing require?

The design is particularly suitable for rotating applications with moderate to high speeds where protection against dirt particles is required. The integrated gap seals help to keep solid particles out of the raceway area. As the roller bearing is designed for a temperature range of -20 to +120 degrees, it can be used in thermally demanding operating environments.

What is the purpose of the C3 clearance and cover plates in this bearing?

The -2Z/C3 design combines non-contacting metal cover plates with increased radial bearing clearance. The Z-plates on both sides keep out coarse dust without generating additional friction or frictional heat at the sealing lips. This ensures that the bearing continues to run smoothly. The designation C3 indicates a larger radial clearance. This clearance serves to compensate for thermal expansion when the bearing heats up or for tight fits.
