Tapered Roller Bearings FAG 32208
The 32208 tapered roller bearing from FAG Wälzlager, with main dimensions of 40 × 80 × 24.75 mm, is designed to withstand high radial and single-direction axial loads in mechanical engineering applications.
The 32208 tapered roller bearing is a complete, single-row roller bearing in a standard design. This component from FAG Wälzlager is characterised by tapered rollers and raceways, the imaginary tips of which meet at the axis of rotation. This geometry ensures low-friction operation under mixed loads. The bearing has a 40 mm bore, an 80 mm outer diameter and a width of 24.75 mm.
What is the 32208 tapered roller bearing suitable for in operation?
This single-row roller bearing is designed for bearing arrangements where high radial forces and unidirectional axial forces act simultaneously. As a single tapered roller bearing can only accommodate axial forces in one direction, in practice it is usually mounted in a mirror-image configuration opposite a second bearing. The inner ring, including the roller cage, and the outer ring can be fitted separately, which simplifies installation in machine housings.
What is important to consider regarding installation and the P0/PN tolerance class?
The bearing is manufactured to the standard tolerance P0/PN, which is also designated as ABEC 1 and is designed for standard industrial applications. When fitting, please note that the operating clearance is only adjusted during installation by aligning the bearing axially against the mating bearing. The integrated sheet steel cage guides the tapered rollers in an orderly manner. The component is suitable for a temperature range of -30 to +120 degrees, making it compatible with suitable lubricating oils or rolling bearing greases.
What are the main dimensions of the 32208 tapered roller bearing?
This roller bearing has an inner diameter of 40 mm, an outer diameter of 80 mm and a total width of 24.75 mm. As a complete tapered roller bearing, the scope of supply includes both the inner ring with its set of rollers and the corresponding outer ring, meaning the components are supplied ready for immediate installation.
What load directions can the single-row roller bearing accommodate?
A single-row tapered roller bearing can accommodate high radial and axial forces from a single direction simultaneously. To accommodate axial forces from both directions, a second bearing is usually fitted in an O or X arrangement, mirroring the first bearing on the same shaft, so that the forces are supported in opposite directions.
What is the temperature range for which the bearing is specified?
The permissible temperature range is between -30 and +120 degrees. Within these limits, the rings and the sheet steel cage retain their dimensional stability. For operation, a lubricant must be selected whose operating range corresponds to the thermal conditions of the application.
What does the designation ‘tolerance class P0/PN’ or ‘ABEC 1’ mean?
P0 and PN denote the standard tolerance for dimensional and running accuracy, which corresponds to the ABEC 1 classification. This tolerance class meets the requirements of conventional mechanical engineering applications without the need for special fits or tighter tolerance classes.
How is the clearance adjusted in the 32208 tapered roller bearing?
The bearing clearance for this type of bearing is not specified by the manufacturer. You determine the axial clearance during assembly by positioning the bearing against a second rolling bearing, for example using shaft nuts, spacer rings or shims on the housing cover.
What are the features of the integrated sheet steel cage?
The sheet steel cage guides the individual tapered rollers, prevents them from coming into contact with one another and helps to ensure an even load distribution. It is characterised by its low weight and is designed for the entire permissible temperature range of -30 to +120 degrees.
