230/600/W33

230/600/W33 is a double-row self-aligning roller bearing with an outer ring annular oil groove and three lubrication holes (W33) (the common basic type is CA brass cage, cylindrical bore, and derivatives include CAK conical bore, C3 clearance, etc.). The core positioning is to provide "double-row heavy-load bearing + spherical self-aligning compensation for installation coaxiality error / shaft deflection + W33 outer ring annular oil groove + three lubrication holes to support on-line oil replenishment for long-term continuous operation + optional conical bore for convenient disassembly / pre-tightening adjustable + C3 clearance to adapt to working conditions thermal deformation + high rigidity stable support + suitable for grease/oil lubrication and on-line maintenance" for ultra-large low-speed heavy-load equipment such as metallurgical rolling mill supporting rolls, mining ball mill, cement vertical mill / rotary kiln, heavy-duty crane rotating mechanism, large gearboxes, etc. It meets the radial-dominated and bidirectional axial auxiliary heavy-load requirements in ultra-large low-speed heavy-load scenarios, adapts to working conditions thermal deformation and shaft deflection, ensures the equipment's long-term stable operation, reduces maintenance costs and improves maintenance efficiency.
