Spherical Roller Bearings SKF 24034 CC/C3W33

The SKF 24034 CC/C3W33 self-aligning roller bearing, with a 170 mm bore and an outer diameter of 260 mm, accommodates heavy radial loads and misalignment.

The SKF 24034 CC/C3W33 self-aligning roller bearing is a rolling bearing designed for demanding industrial applications involving high radial loads. Thanks to the spherical outer ring raceway, the bearing adjusts its angular position, thereby compensating for misalignment and shaft deflection during operation. Manufactured from standard rolling-element bearing steel 100Cr6, this open bearing operates within a temperature range of -30 to +200 degrees.

What is the 24034 CC/C3W33 self-aligning roller bearing suitable for?

Design engineers and maintenance personnel use this design primarily in heavy-duty industrial bearing arrangements and in general mechanical engineering. Wherever elastic deformations of the shaft or housing inaccuracies occur, the angular-compensating geometry counteracts impermissible edge stresses. The dimensions – with a 170 mm bore, 260 mm outer diameter and 90 mm width – offer high load capacity whilst maintaining a compact axial width. The bearing runs smoothly even under varying operating conditions.

What do the designations CC, C3 and W33 mean in terms of operation?

The suffix CC denotes the version with a sheet steel cage, which guides the rollers and keeps friction to a minimum during operation. The designation W33 refers to a circumferential lubrication groove with lubrication holes in the outer ring, through which lubricant reaches the rolling elements directly. The increased radial clearance C3 compensates for thermal expansion at high operating temperatures. During assembly, dimensional accuracy in accordance with standard tolerance (PN) and the increased running accuracy of class P5 must be taken into account.
