Spherical Roller Bearings SKF 22332 CCK/C3W33
The SKF 22332 CCK/C3W33 self-aligning roller bearing, measuring 160 × 340 × 114 mm, compensates for misalignment and accommodates heavy radial and combined loads.
The SKF 22332 CCK/C3W33 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. With a bore of 160 mm, an outer diameter of 340 mm and a width of 114 mm, this bearing accommodates high radial forces as well as axial forces on both sides. Thanks to the hollow-spherical outer ring raceway, the bearing can adjust to shaft deflection with angular misalignment. The material, made from standard roller bearing steel 100Cr6, and the sheet steel cage support an operating temperature range of -30 to +200 degrees Celsius.
In which applications is the 22332 CCK/C3W33 self-aligning roller bearing used?
This self-aligning roller bearing is primarily suitable for heavy machinery with shaft deflection or misalignment between the shaft and housing. Typical applications include heavy-duty industrial applications involving high radial loads and shock loads. As this is an open bearing, it can be flexibly integrated into the customer’s lubrication systems. The integrated circumferential groove with lubrication holes in the outer ring allows for direct relubrication whilst the bearing is in operation. This ensures that the roller set remains evenly lubricated even under continuous load.
What is the function of the tapered bore and the C3 clearance?
The suffixes provide information about specific design features for your installation situation. The designation ‘K’ stands for a tapered bore with a taper ratio of 1:12. This design facilitates mounting on tapered shaft seats or using mounting and withdrawal sleeves. At the same time, the bearing has a C3 clearance class. This slightly increased radial bearing clearance compensates for the expansion of the inner ring during press-fitting as well as thermal expansion. Furthermore, the increased running accuracy to tolerance class P5 ensures high concentricity.
What are the dimensions of the 22332 CCK/C3W33 self-aligning roller bearing?
This roller bearing has a bore of 160 mm, an outer diameter of 340 mm and a width of 114 mm. These dimensions place it amongst the heavy-duty series used in mechanical and plant engineering. Please check the available installation space and the correct mounting dimensions in the bearing housing before fitting.
What does the tapered bore on this bearing mean?
A tapered bore has a taper ratio of 1:12, meaning that the internal diameter tapers across its width. This design can either be fitted directly onto a tapered shaft journal or mounted on a cylindrical shaft using a clamping or withdrawal sleeve. This makes installation and removal considerably easier.
Why does the bearing have a clearance rating of C3?
C3 bearing clearance refers to a slightly increased radial bearing clearance compared with the standard version. When tightened onto a tapered bearing seat, the inner ring expands, thereby reducing the operating clearance. The C3 bearing clearance helps to ensure that, after press-fitting and following operational heating, sufficient clearance remains to allow for smooth running.
What is the purpose of the ‘W33’ marking on the outer ring?
The designation W33 refers to a lubrication groove and lubrication holes in the outer ring of the bearing. This design facilitates the supply of lubricant directly into the interior of the bearing. Via grease nipples on the housing, the lubricant is distributed evenly to both sets of rollers, which reduces friction and wear during operation.
Within what temperature range can the bearing be operated?
The spherical roller bearing is designed for operating temperatures ranging from -30 to +200 degrees Celsius. The dimensionally stable sheet steel cage and the 100Cr6 rolling bearing steel maintain their dimensional accuracy within this range. Ensure that you select a lubricant whose thermal suitability is matched to the system’s specific operating range.
How does tolerance class P5 differ from standard bearings?
This bearing combines dimensional accuracy in accordance with standard tolerance PN with the enhanced running accuracy P5. Whilst the mounting dimensions comply with the basic standard, the rotating inner ring has tighter concentricity tolerances. This feature promotes smooth, low-vibration operation and is recommended for machines with increased requirements for concentricity.
