The SKF 33205 tapered roller bearing, with its main dimensions of 25 × 52 × 22 mm, can simultaneously withstand high radial and axial forces in one direction.
The 33205 tapered roller bearing is a single-row roller bearing in metric design in the standard version. The manufacturer, SKF, produces this complete tapered roller bearing in the high-performance Explorer version. The tapered rollers transmit radial and axial forces from a single direction with high rigidity. Thanks to the separate design comprising an inner ring with a set of rollers and a flangeless outer ring, you can mount both bearing components independently of one another on the shaft and in the housing.
This bearing is primarily used in applications where combined radial and axial loads occur. As a single tapered roller bearing, by design, can only accommodate axial forces in one direction, it is usually fitted in pairs in an O or X arrangement. The second bearing supports the opposite axial direction. The permissible temperature range extends from -30 to +120 degrees, making the component suitable for varying thermal environmental conditions.
The component features a guided sheet steel cage, which maintains an even spacing between the tapered rollers and withstands vibrations during operation. With a tolerance class of P0/PN or ABEC 1, the bearing complies with the standard tolerances for general mechanical engineering. When installing the bearing, ensure that the axial clearance or preload relative to the mating bearing is set precisely, as this setting has a significant influence on subsequent load distribution and service life.
The bearing has an inner diameter of 25 mm, an outer diameter of 52 mm and a total width of 22 mm. It is a complete tapered roller bearing, comprising the inner ring with a guided set of rollers and the corresponding outer ring.
The Explorer class comprises advanced roller bearings from SKF featuring optimised surface finish on the contact surfaces and refined roller geometry. These design modifications improve run-in behaviour, facilitate the formation of a lubricating film between the roller end face and the raceway, and reduce internal friction during operation.
Due to the angular contact of the tapered rollers, any radial load generates an internal axial force component. A single tapered roller bearing can only accommodate axial forces in one direction. It is only when a pair of bearings is arranged opposite a mirror-image-mounted mating bearing that a rigid bearing arrangement is created, which supports loads in both directions.
The permissible temperature range is between -30 and +120 degrees. The dimensional stability of the rings and the integrated sheet steel cage cover this temperature range. When designing the lubrication system, care must be taken to ensure that the selected lubricant is suitable for the same temperature range.
This designation refers to the standard tolerance class for rolling bearings in the industrial and automotive sectors. It specifies the permissible dimensional, geometric and running accuracies for inner and outer rings. Components in this class meet the standard precision requirements for general mechanical engineering without any specific high-precision specifications.
Yes, the bearing is supplied as an open unit without integrated contact seals. Before commissioning, apply a suitable grease or lubricating oil, depending on the design and operating requirements. Furthermore, the open design requires effective seals in the surrounding housing structure to protect against dirt and moisture.
