23256 CCK/C3W33

The 23256 CCK/C3W33 is a high-performance spherical roller bearing engineered for heavy-duty industrial applications where shaft misalignment and substantial radial loads are constant challenges. Featuring a 280mm bore and a 500mm outside diameter, this unit utilizes two rows of symmetrical rollers and a flangeless inner ring to minimize internal friction while maximizing load distribution. The "CCK" designation signifies a 1:12 tapered bore, specifically designed for mounting on adapter or withdrawal sleeves, providing a secure, high-precision fit in vibrating or high-speed environments.

Optimized for durability and ease of maintenance, this bearing incorporates the "W33" feature, which consists of an annular groove and three lubrication holes in the outer ring to facilitate efficient grease or oil circulation. The "C3" internal clearance offers the necessary thermal expansion buffer, preventing premature seizure during continuous, high-temperature operations common in mining, paper mills, and heavy gearboxes. By integrating advanced metallurgical standards with a robust cage design, the 23256 CCK/C3W33 ensures extended service intervals and superior resistance to edge stresses, even in the most demanding site conditions.
