Spherical Roller Bearings SKF 23034 CCK/C4W33
The SKF 23034 CCK/C4W33 self-aligning roller bearing (170x260x67 mm), with a tapered bore and increased C4 radial clearance, offers high operational reliability under thermal and mechanical loads.
The SKF 23034 CCK/C4W33 self-aligning roller bearing is a double-row roller bearing designed for industrial applications involving combined loads. This open bearing, made from standard 100Cr6 rolling-element bearing steel, has a bore diameter of 170 mm, an outer diameter of 260 mm and a width of 67 mm. A sturdy sheet steel cage guides the rollers in both raceways. The integrated lubrication groove with lubrication holes in the outer ring allows lubricant to be fed directly into the bearing interior. This design is suitable for operating temperatures ranging from –30 to +200 degrees Celsius.
What is the 23034 CCK/C4W33 self-aligning roller bearing suitable for?
This self-aligning roller bearing accommodates high radial forces as well as axial loads in both directions whilst compensating for unavoidable shaft deflection. The spherical raceway in the outer ring automatically compensates for misalignment between the inner and outer rings, thereby preventing edge loading. Typical applications include industrial bearing arrangements subject to combined loads and demanding operating conditions.
Design engineers and maintenance personnel rely on this design when high loads are applied to flexible shafts. The running accuracy to Class P5 ensures low-vibration concentricity during continuous operation.
What are the advantages of a tapered bore and C4 clearance?
The tapered bore with a 1:12 taper enables precise mounting on tapered shaft seats or using clamping and withdrawal sleeves. Users can adjust the desired fit via the axial displacement. The increased C4 radial bearing clearance helps to ensure that the bearing does not become stressed, even when heated or in a tight fit.
As the bearing has an open design, the assembly requires a suitable housing seal to prevent the ingress of contaminants. The lubricant is fed directly between the roller sets via the W33 system, which simplifies maintenance work in demanding industrial environments.
What are the key features of the 23034 CCK/C4W33 self-aligning roller bearing?
This double-row roller bearing from SKF features a tapered bore with a 1:12 taper, a lubrication groove with lubrication holes in the outer ring, and a significantly increased C4 radial clearance. Measuring 170 × 260 × 67 mm, it compensates for misalignment whilst simultaneously accommodating high radial and axial loads.
What are the dimensions of bearing 23034 CCK/C4W33?
The bearing has a bore of 170 mm, an outer diameter of 260 mm and a width of 67 mm. These key dimensions comply with the standard for self-aligning roller bearings and allow for a precise fit when installed in machine housings and gearbox units designed for this purpose.
What does the suffix C4 mean for this bearing?
The designation C4 indicates a significantly increased radial bearing clearance, which is greater than the standard value and exceeds Class C3. This increased operating clearance compensates for thermal expansion at elevated operating temperatures, as well as for the reduction in bearing clearance caused by the inner ring being pressed onto the shaft.
What is the function of feature W33 on the outer ring?
The designation W33 indicates a circumferential lubrication groove with lubrication holes on the outer ring of the bearing. This allows fresh lubricant to flow directly between the two rows of rollers. This feature simplifies relubrication whilst the bearing is fitted and helps to ensure an even distribution of the lubricant.
Why is the bore tapered?
A 1:12 taper is used for mounting on tapered shaft seats or for flexible mounting on cylindrical shafts using clamping or withdrawal sleeves. By axially adjusting the inner ring, fitters can set the remaining radial play very precisely before commissioning.
What is the permissible temperature range for the bearing?
The bearing, made from standard 100Cr6 rolling bearing steel, is designed for an operating temperature range of -30 to +200 degrees Celsius. The integrated sheet steel cage retains its dimensional stability throughout this entire temperature range, making the bearing suitable for thermally demanding operating environments in industrial manufacturing.
