The SKF 6205-2Z deep groove ball bearing, with dimensions of 25x52x15 mm and non-contacting end shields, offers low-friction operation for demanding industrial applications.
The 6205-2Z deep groove ball bearing is a single-row radial rolling bearing in the SKF Explorer performance class. With a bore of 25 mm, an outside diameter of 52 mm and a width of 15 mm, this component primarily accommodates radial loads and moderate axial loads. The outer ring has no flange or groove. Manufactured from standard 100Cr6 rolling-bearing steel and fitted with a sheet steel cage, this bearing is designed for operating temperatures ranging from -20 to +120 degrees.
It is primarily used in rotating shaft assemblies where low friction torque and protection against coarse dirt particles are required. Typical applications include high-speed rotating shafts subject to moderate radial loads. Thanks to the non-contact gap seal, the lubricant remains within the bearing chamber without generating additional frictional heat. For maintenance engineers and original equipment manufacturers, this component offers a suitable solution for continuously rotating shafts at high speeds with minimal maintenance requirements.
The sheet metal end caps on both sides (designation -2Z) protect the bearing interior from solid contaminants and keep the grease inside, whilst the standard radial bearing clearance ensures stable operation under standard installation conditions. A key feature lies in the manufacturing process: dimensional accuracy complies with Class P6, whilst running accuracy in accordance with Class P5 specifies even tighter concentricity tolerances. This reduces vibrations during operation, which plays a particularly important role in drives with high concentricity requirements.
With an internal diameter of 25 mm, an external diameter of 52 mm and a width of 15 mm, the component complies with standardised dimensions. These dimensions allow for direct replacement in existing housings and on shafts of the same dimensions, without the need for any modifications to the surrounding structure.
The designation -2Z indicates cover discs made of profiled sheet steel fitted on both sides. Unlike ablative rubber seals, these cover plates do not come into contact with the inner ring. This means that no additional frictional resistance is generated, which facilitates high rotational speeds whilst effectively preventing the ingress of dust and dirt particles.
The tolerance classes P6 for dimensional accuracy and P5 for running accuracy exceed the standard level of normally tolerated bearings. P6 defines tighter dimensional tolerances for the bore and outer diameter, whilst P5 ensures more precise radial and axial concentricity. This reduces the tendency for vibration and contributes to smooth shaft guidance.
This SKF rolling bearing is specified for an operating temperature range of -20 to +120 degrees. This range covers typical industrial operating conditions in enclosed spaces and in standard units. In applications operating close to the limit values, thermal expansion of the surrounding components should always be taken into account.
The standard radial bearing clearance refers to the factory-set internal radial clearance between the rolling elements and the raceways under reference conditions. It is suitable for standard fits and standard operating temperatures, where there are no extreme temperature differences between the inner and outer rings, nor are unusually tight press fits selected.
The inner and outer rings, as well as the rolling elements, are manufactured from standard roller bearing steel (100Cr6), which offers high compressive strength and dimensional stability. A sheet steel cage serves as the guide for the balls, keeping the rolling elements at a uniform distance apart.
