23948CA/W33

23948CA/W33 is a high-performance self-aligning roller bearing. Its core function is to provide stable and reliable rotational support for heavy machinery with medium-speed heavy load, requiring continuous lubrication and maintenance, and where there are installation errors or deflections of the shaft system. It combines the core advantages of the "CA" and "W33" suffixes - "CA" represents an integral brass cage + inner ring without an intermediate guard, with high strength and impact resistance, capable of stably guiding the movement of rollers, suitable for heavy-duty conditions; "W33" corresponds to the annular oil groove and three oil holes on the outer ring, allowing for convenient lubricant replenishment during operation, reducing friction loss and improving heat dissipation, meeting high-frequency lubrication requirements. At the same time, relying on the spherical outer raceway of the self-aligning roller bearing, it can automatically compensate for 1° - 2.5° of shaft alignment deviation, avoiding internal stress concentration, capable of withstanding large radial loads and bidirectional axial loads (basic rated dynamic load is approximately 850kN, static load is approximately 1380kN, and the limit speed is approximately 1700r/min), widely adapting to mining crushers, metallurgical rolling mills, large motors and other equipment, ensuring the long-term operation of the equipment in heavy, vibrating and frequently lubricated complex working conditions.
