Tapered Roller Bearings SKF 32048 X

This is a single-row, separable roller bearing in a standard design. It consists of an inner ring with a guided set of rollers and a separate outer ring. This split design facilitates the fitting of the individual rings onto the shaft and housing. The integrated sheet steel cage keeps the tapered rolling elements at a uniform distance apart and guides them along the raceways.

The bearing accommodates high radial forces and, at the same time, axial forces from one direction. Due to the inclined contact angle of the tapered rollers, the axial force component is supported by the guide flange of the inner ring. To accommodate axial forces from both directions, combine the component with a second tapered roller bearing in a mirror-symmetrical arrangement on the shaft.

The design is intended for operation within a temperature range of -30 to +120 degrees Celsius. Both the sheet steel cage and the heat-treated bearing components retain their dimensional stability within this range. Select a lubricant for use whose viscosity and specification are suited to the prevailing operating temperatures of your system.

The bearing complies with tolerance class P0/PN, which is also known internationally as ABEC 1. This standard tolerance meets the usual accuracy requirements in general mechanical engineering and industrial gearboxes. It enables cost-effective manufacture of the connecting parts whilst ensuring a precise fit for standardised rolling bearing applications.

Single-row tapered roller bearings do not have a factory-set bearing clearance. The operating clearance is only created during installation through axial alignment against a second bearing fitted in a mirror-image configuration. You can adjust the required preload or bearing clearance using spacer rings, shaft nuts or housing covers, in accordance with the design specifications of your system.
