23048CAK

23048CAK is a double-row self-aligning roller bearing with an inner diameter of 240mm, an outer diameter of 360mm, and a width of 92mm. Its core function is to provide a main support for the shaft systems of heavy-duty and highly-vibratory equipment such as metallurgical rolling mills, mining crushers, cement vertical mills, heavy-duty reducers, and port cranes. This support is easy to install and disassemble, and allows for precise adjustment of the radial clearance. The suffix "CA" indicates that it is a symmetrical spherical roller with a copper alloy sleeve as the cage. It has strong shock absorption and vibration resistance, suitable for high-frequency vibration conditions. The suffix "K" represents a 1:12 conical hole design, which is suitable for installing a release sleeve or locking sleeve on a shaft without a shoulder. The assembly is quick and can precisely control the radial clearance through nut pre-tightening. It can compensate for an installation misalignment of up to 2° and shaft deflection. It has bidirectional axial bearing capacity. The material is GCr15 high-carbon chromium bearing steel that undergoes deep quenching and heat treatment to HRC60-64. It is wear-resistant and fatigue-resistant. The basic rated dynamic load is approximately 1160kN, and the static load is approximately 2140kN. The grease lubrication limit speed is approximately 530-550r/min, and the oil lubrication is approximately 670-700r/min. The recommended practical use is to control within 70% of the limit speed. General lithium-based lubricating grease should be pre-filled. The heavy-load impact and other harsh scenarios can be replaced with suitable lubricating grease. Compared to the cylindrical hole model, it is more suitable for the assembly requirements of shafts and meets the dual demands of long-term continuous stable operation and efficient maintenance of the equipment.
