23938CKA/W33

The core positioning of the 23938CKA/W33 bearing is a type of self-aligning roller bearing that is suitable for heavy loads, requires convenient installation, and has high requirements for continuous lubrication. It is specifically designed for heavy equipment with axis alignment deviations, frequent maintenance of lubrication, or difficult stoppage for maintenance. From the structural characteristics, "CKA" represents that the inner ring has no flange and an active cage, uses a brass solid cage, and the inner hole is a 1:12 conical hole, which can be used with a locking sleeve or a disassembly sleeve, enhancing the convenience of installation and disassembly while compensating for the thermal expansion of the shaft and installation errors; "W33" indicates that the outer ring has a circular oil reservoir and three oil holes, supporting external continuous oil lubrication, which can effectively reduce friction and wear between the raceway and rolling elements, and extend the service life of the bearing. The standard size of this bearing is an inner diameter of 190mm, an outer diameter of 260mm, and a width of 52mm. It can withstand large radial loads and certain bidirectional axial loads, and also has the automatic self-aligning capability (allowing the shaft to tilt by no more than 1°-2.5° from the center line of the outer ring). It is mainly suitable for heavy-duty equipment such as mining machinery, metallurgical rolling mills, large reducers, wind power equipment, etc., providing stable support and long-term operation guarantee for their rotating components.
