Deep Groove Ball Bearings SKF 6204 -2Z

The SKF 6204-2Z deep groove ball bearing, measuring 20 × 47 × 14 mm, features non-contact sheet metal shields on both sides and is designed for rotary applications requiring high running accuracy.

The SKF 6204-2Z deep groove ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with a bore of 20 mm, an outer diameter of 47 mm and a width of 14 mm. As part of the SKF Explorer range, this bearing is characterised by a combination of dimensional accuracy to tolerance class P6 and running accuracy to P5. Design engineers and maintenance personnel primarily use this type of bearing in drives and shaft mountings where radial forces predominate and axial guidance loads occur.

What is the 6204-2Z deep groove ball bearing suitable for in practice?

The bearing is primarily used in applications that require low-friction operation at higher speeds. The design primarily accommodates radial loads, but thanks to the deep raceways, it also supports moderate axial forces in both directions. The sheet steel cage ensures that the spacing between the rolling elements remains evenly maintained during alternating rotational movements.

What are the characteristics of the 2Z end plates and tolerances?

The end plates on both sides (designation -2Z) are made of profiled sheet steel. They act as a non-contact gap seal, which means that, unlike with sliding seals, no additional frictional torque is generated. This design protects the bearing interior from coarse particles and dust. The tighter tolerance class – P6 for dimensions and P5 for concentricity – reduces vibrations and ensures low-vibration operation. The bearing is suitable for use in temperatures ranging from –20 to +120 degrees Celsius.
