23040CK

23040CK is a double-row self-aligning roller bearing with an inner diameter of 200mm, an outer diameter of 310mm, and a width of 82mm (where "CK" represents symmetrical spherical rollers, double flanges on the inner ring, copper alloy cage, 1:12 conical hole design, and is suitable for fixed sleeve/retread sleeve installation). The core function is to serve as a shaft system support component for heavy-duty applications that require convenient disassembly and self-aligning compensation. It can compensate for an installation misalignment of 2° and can withstand large radial loads and bidirectional medium axial loads. The conical hole combined with the fixed sleeve enables quick positioning and disassembly on a smooth shaft without a shoulder, suitable for equipment with heavy-duty requirements and frequent maintenance and disassembly, such as support rollers of metallurgical rolling mills, eccentric shafts of mining crushers, shafts of cement vertical mills, and transmission shafts of heavy machinery. It is a heavy-duty detachable support solution with high load-bearing capacity, impact resistance, self-aligning property, and convenient assembly and disassembly. It is also more suitable for heavy-duty maintenance scenarios that require quick assembly and disassembly and do not require high-precision shoulder positioning. Different from the CA1 model with a cylindrical hole, its combination of conical hole and fixed sleeve makes the installation and on-site replacement of the smooth shaft more efficient, suitable for working conditions with high vibration and impact and high maintenance frequency.
