Tapered Roller Bearings SKF 32222
The SKF 32222 tapered roller bearing (110x200x56 mm) is suitable for high radial and single-direction axial loads in industrial applications.
The SKF 32222 tapered roller bearing is a single-row roller bearing in a standard design. Thanks to the tapered arrangement of the rolling elements, this bearing can simultaneously accommodate heavy radial and axial forces in one direction. The complete tapered roller bearing assembly comprises an inner ring with a set of rollers and the corresponding outer ring. The integrated sheet steel cage guides the tapered rollers evenly along the raceway and withstands vibrations during day-to-day operation.
What is the single-row tapered roller bearing 32222 suitable for?
Shaft bearings subjected to simultaneous radial and axial forces represent the primary field of application. Such applications involve combined loads that exceed the capacity of conventional radial bearings. Because single-row tapered roller bearings can only accommodate axial forces in one direction, designers frequently install the 32222 tapered roller bearing in a mirror-image configuration with a second bearing as a supported arrangement. This enables the bearing assembly to effectively absorb tilting moments and guide shafts with precision in mechanical engineering.
What are the key features of the 32222’s design and tolerance class?
This model complies with the standard tolerance P0/PN or ABEC 1. It therefore meets common precision requirements in general mechanical engineering. SKF’s Explorer design is based on optimised contact geometries between the roller ends and the raceway flanges, which reduces frictional resistance. The permissible temperature range is from –30 to +120 degrees Celsius. Before installation, the dimensions of 110 mm bore, 200 mm outer diameter and 56 mm width must be checked to ensure they match the respective bearing seat.
What are the dimensions of the 32222 tapered roller bearing?
With an internal diameter of 110 mm, an external diameter of 200 mm and a total width of 56 mm, this bearing complies with the standardised 32222 series. These dimensions are crucial for the fit on the shaft and in the housing seat. Before fitting, it is advisable to check these dimensions against the design drawings.
What loads can the 32222 tapered roller bearing withstand?
The truncated cone-shaped rolling elements simultaneously absorb high radial forces and unidirectional axial forces. To accommodate axial forces from varying directions, users usually fit a second tapered roller bearing in a face-to-face arrangement. This paired arrangement creates a rigid bearing assembly that guides the shaft precisely and minimises guidance play during operation.
What does the SKF Explorer designation mean for this bearing?
SKF manufactures Explorer-class bearings with improved surface finish on the raceways and modified contact profiles at the roller ends. This design reduces internal friction and minimises stress peaks at the edges. The formation of a uniform lubricating film contributes to smooth running and stable operation during use.
What is the permissible temperature range for bearing 32222?
The bearing is designed for operating temperatures ranging from -30 to +120 degrees Celsius. The integrated sheet steel cage and the metal bearing rings retain their dimensional stability within this temperature range. To ensure safe operation, the selected lubricant must also be suited to the specific operating temperature in order to prevent the lubricating felt from tearing.
Why can a tapered roller bearing be dismantled?
In tapered roller bearings, the inner ring, together with the roller cage, forms a single unit, whilst the outer ring is flangeless and can be removed separately. This design facilitates the step-by-step installation of the shaft and housing. Furthermore, the ability to dismantle the bearing allows for the precise adjustment of the axial clearance during the final assembly of the unit.
What features does the built-in sheet steel cage offer?
The sheet steel cage guides the rollers with minimal play and withstands mechanical vibrations during operation. It is characterised by its low weight and takes up little space inside the bearing. This promotes the even distribution of lubricant between the rolling elements and the raceways.
