230/560K/W33

230/560K/W33 is a double-row self-aligning roller bearing with a lubrication groove on the outer ring and three lubrication holes (W33), a conical hole (K), and C3 radial clearance. The core positioning is to provide "conical hole convenient installation + heavy load bearing + self-aligning compensation + W33 online lubrication + C3 clearance adaptation to working condition deformation + detachable shaft system adaptation + high rigidity stable support" for ultra-large low-speed heavy-load equipment such as metallurgical rolling mill supporting rolls, mining ball mills, and cement vertical mills. It is suitable for adapting to shaft deflection, installation coaxiality errors, and working condition thermal deformation, meeting the requirements for low-speed heavy-load continuous operation and long-term lubrication maintenance. It is suitable for ultra-large low-speed heavy-load scenarios that require rapid disassembly, adjustable radial preload, compact space, and online lubrication maintenance, and takes into account high reliability and long-term stable operation. It is particularly suitable for ultra-large low-speed heavy-load scenarios with strict requirements for installation maintenance efficiency, shaft preload adjustment, working condition thermal deformation compensation, and online lubrication maintenance.
