SKF 23152 CACK/C3W33 STATIC SMOOTH DRUM ROLLER

Technical Description

The SKF 23152 CACK/C3W33 is a heavy-duty spherical roller bearing designed for applications requiring high radial and axial load capacity, and the ability to accommodate shaft misalignment. It features a **tapered bore (1:12 ratio) with a bore diameter of 260 mm (10.24 in)**, an **outside diameter of 440 mm (17.32 in)**, and an overall width of 144 mm (5.67 in)**. The bearing has **two rows of symmetrical rollers** running on a solid inner ring and a solid outer ring with a concave spherical raceway, enhancing its capacity to handle misalignment and shaft deflections. It employs a **C3 radial internal clearance**, optimized for increased operational clearance to support thermal expansion and reduce friction under heavy loads. The cage is made of **machined brass**, providing stable roller guidance and durability under heavy and oscillating loads. This bearing is open (no seals), enabling relubrication, which extends service life and aids in maintenance. The bearing steel material offers high wear resistance and long service life. Additionally, the bearing has **normal dimensional tolerance and P5 run-out tolerance class**, ensuring precise and reliable operation. It supports a **dynamic load capacity of approximately 2664 kN and a static load of about 3900 kN**, suitable for harsh industrial environments. The bearing runs at a maximum limiting speed of 1400 rpm, with a reference speed of 1100 rpm. These features make the SKF 23152 CACK/C3W33 suited for heavy machinery, including continuous casters, wind turbines, and vibrating equipment where durability and alignment tolerance are critical.
