Deep Groove Ball Bearings SKF 6204

The SKF 6204 single-row deep-groove ball bearing, measuring 20 × 47 × 14 mm, offers enhanced precision in P6 and P5 tolerance classes for demanding rotational movements.

The SKF 6204 deep groove ball bearing is a versatile rolling bearing designed primarily for radial loads, whilst also accommodating moderate axial forces in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel, this bearing corresponds to the Explorer design. With a 20 mm bore, 47 mm outer diameter and 14 mm width, the component fits precisely into cylindrical housings. The sheet steel cage guides the rolling elements over an operating temperature range of –20 to +120 degrees Celsius.

What are the industrial applications for the 6204 deep groove ball bearing?

This open bearing is particularly useful where housing designs already enclose the lubrication point and seal it off externally against contamination. Typical applications include enclosed units with oil circulation lubrication or external sealing systems. As lubricant can circulate unhindered, the open design is suitable for oil or relubrication systems. At constant speeds, the standard radial bearing clearance promotes smooth running without excessive heat build-up during normal operation.

What advantages do tolerance classes P6 and P5 offer in the 6204 model?

With this bearing, the manufacturer combines dimensional accuracy to P6 with enhanced running accuracy to P5. These tighter tolerances limit runout errors when the shaft is rotating. This makes the component particularly suitable for designs with high demands on smooth running and low vibration. Before installation, it must be checked whether the fits between the shaft and the housing bore are matched to these accuracy grades in order to make effective use of the Explorer-class’s properties.
