The 31319 tapered roller bearing from SKF Wälzlager, with dimensions of 95 × 200 × 49.5 mm, accommodates high combined radial and axial loads.
The single-row tapered roller bearing 31319 supports shafts under simultaneous radial and axial loads in industrial drives. As a complete tapered roller bearing in the standard design, the unit consists of an inner ring with a set of rollers and the corresponding outer ring. The integrated sheet steel cage guides the tapered rolling elements with low friction. The bearing covers a temperature range of –30 to +120 degrees and complies with the standard tolerance class P0/PN or ABEC 1.
This size is primarily used in mechanical drives and bearing arrangements in mechanical engineering, where unidirectional axial forces act on the shaft alongside high radial loads. Thanks to the angled raceways, the design transfers axial loads directly via the flange. To accommodate alternating axial forces, the bearing is usually fitted in pairs, with one bearing positioned in a mirror image to the other.
As the inner and outer rings can be fitted separately, installation can be carried out in stages. During assembly, care must be taken to set the operating clearance precisely, as the axial bearing clearance is only established when the bearing is aligned against the mating bearing. The integrated sheet steel cage withstands mechanical stresses in the range from -30 to +120 degrees. Before commissioning, the open unit requires a suitable lubricant and an external seal for the housing environment.
The bearing has an inner diameter of 95 mm, an outer diameter of 200 mm and a total width of 49.5 mm. These dimensions determine the installation space required on the shaft and in the housing seat.
A sheet steel cage maintains a precise spacing between the tapered rollers and prevents direct contact between the rolling elements. The material is characterised by its dimensional stability within a temperature range of -30 to +120 degrees and can withstand the usual mechanical vibrations encountered during operation.
Owing to its conical design, the assembly absorbs both radial and axial forces from a single direction. Where loads act from both directions, the assembly requires a second tapered roller bearing, arranged in a mirror-image configuration, on the same shaft.
This classification describes the standard level of accuracy for dimensional and running errors in accordance with international standards. Bearings in this tolerance class are suitable for the vast majority of conventional mechanical engineering applications that do not have specific precision requirements.
The components are designed for an operating range of between -30 and +120 degrees. Within these limits, the raceways, rolling elements and sheet steel cage retain their dimensional stability provided they are properly lubricated.
No, this model is an open design without integrated contact seals. Designers therefore fit the bearing housing with external sealing elements, such as shaft seals, to prevent lubricant loss and the ingress of dirt.
