Overview
The SKF 23034 CCK/C3W33 is a premium spherical roller bearing engineered for demanding industrial applications requiring high radial and axial load capacity. This double-row unit features a tapered bore (1:12 ratio), making it ideal for applications where misalignment and shaft deflection tolerance are critical. The open design with C3 internal clearance and W33 oil grooves/holes supports both grease and oil lubrication strategies.
Key Features
- Double-row spherical roller design for enhanced load-carrying capacity and stability
- Tapered bore (1:12) with steel cage for convenient mounting via conical sleeve
- C3 radial internal clearance—greater than normal for applications requiring higher running clearance
- W33 lubrication: annular groove and three lubrication holes in outer ring for optimal oil distribution
- Flangeless inner ring with guide ring for self-aligning accommodation of misalignment up to 2 degrees
- Stamped steel cages ensure robust, low-friction operation across demanding speed and load ranges
Technical Specifications
Bore diameter 170 mm, outside diameter 260 mm, width 67 mm. Maximum operating speed 2800 RPM when properly lubricated. Dynamic load rating 745 kN, static load rating 1060 kN. Fillet radius 2.00 mm. Operating temperature range −20 to +390 °F (−29 to +199 °C). Cage material: bearing steel (sheet metal). Precision rating ABEC 1. Bore type tapered 1:12. Closure open, no seals.
Typical Applications
- Heavy machinery and primary reduction gear drives
- Cement mills, crushers, and mining equipment
- Rolling mill pinion shafts and main drive shafts
- Industrial gearboxes handling continuous heavy radial and thrust loads
- Applications requiring self-alignment tolerance and low maintenance intervals
