Spherical Roller Bearings SKF 22324 CCK/C3W33
The SKF 22324 CCK/C3W33 self-aligning roller bearing, with a 120 mm bore and an outer diameter of 260 mm, can accommodate high radial loads as well as misalignment.
The 22324 CCK/C3W33 self-aligning roller bearing is a double-row rolling bearing designed for demanding applications involving combined loads. Thanks to the hollow-spherical outer ring raceway, the bearing automatically compensates for shaft misalignment. Manufactured from standard 100Cr6 rolling bearing steel and featuring a sheet steel cage, it is designed for operating temperatures ranging from -30 to +200 degrees. With a width of 86 mm, the 223 series provides a robust foundation for industrial machinery and plant engineering.
What loads can the 22324 CCK/C3W33 self-aligning roller bearing accommodate?
The bearing is designed primarily for heavy radial loads and simultaneously accommodates axial forces in both directions. Wherever shaft deflection occurs or there are manufacturing-related misalignments between the bearing positions, the self-aligning function counteracts impermissible edge stresses. Design engineers use this design primarily in heavy-duty industrial drives, industrial gearboxes and conveyor systems to compensate for misalignments during operation.
How do the tapered bore and C3 clearance work in the 22324 self-aligning roller bearing?
The tapered bore with a taper ratio of 1:12 allows for mounting directly onto tapered shaft seats or onto cylindrical shafts using shrink sleeves and extraction sleeves. The tight fit can be checked by reducing the radial clearance whilst mounting the bearing. The increased radial clearance (C3) ensures that, following radial press-fitting and due to operational heating, sufficient radial operating clearance remains within the rolling element set. Lubricant is fed directly between the rows of rollers via the W33 circumferential groove with lubrication holes in the outer ring.
What are the key features of the 22324 CCK/C3W33 self-aligning roller bearing?
This double-row roller bearing has a tapered bore of 120 mm, an outer diameter of 260 mm and a width of 86 mm. The bearing automatically compensates for misalignment and has a lubrication groove with lubrication holes in the outer ring for direct lubricant supply.
What does the CCK marking on this bearing mean?
The suffix denotes a design featuring window-type sheet steel cages, an inner ring without a guide ring, and a tapered inner bore with a taper ratio of 1:12. This design facilitates mounting on clamping or withdrawal sleeves and allows for precise clearance adjustment during press-fitting.
Why has bearing clearance class C3 been selected for this version?
Class C3 denotes an increased radial bearing clearance prior to installation, compared with standard conditions. When fitted onto a tapered seat, the bore narrows as the bearing is pushed onto it. The increased initial clearance compensates for this effect as well as for temperature-induced expansion during operation.
What is the function of feature W33 in the outer ring?
The designation W33 denotes a circumferential groove on the outside of the outer ring with several radial through-holes. This allows grease or lubricating oil to flow directly from the outside into the interior of the roller sets. This ensures an even supply of lubricant to both rows of rolling elements without the need for lateral lubrication tubes.
What are the bearing’s tolerance classes?
The dimensional accuracy complies with the standard PN tolerance class, whilst the running accuracy is manufactured to the tighter P5 tolerance class. This combination ensures smooth running of the rollers even under demanding operating conditions, whilst the external dimensions correspond to standard housing seats.
What is the permissible temperature range for the bearing?
The permissible operating temperature range is from -30 to +200 degrees. As this is an open bearing made of 100Cr6 roller bearing steel with a sheet steel cage, it is primarily the chosen lubricant that determines the practical limits during operation. At higher temperatures, lubrication intervals must be adjusted accordingly.
