23028K/W33

The core specification of the 23028K/W33 bearing is a high-capacity, easy-to-lubricate double-row self-aligning roller bearing with an inner diameter of 140mm, an outer diameter of 210mm, and a width of 53mm. The "K" indicates a 1:12 conical hole design, which is suitable for conical shaft installation and facilitates assembly, disassembly, and clearance adjustment. The "W33" represents that the outer ring has a lubrication groove + oil hole to support long-term lubrication replenishment. It also has the self-aligning performance of automatically compensating for shaft installation errors and bending deformation, capable of withstanding large radial loads and certain bidirectional axial loads. It is suitable for heavy-duty, impact, and vibration working conditions and is widely used in mining machinery, metallurgical equipment, heavy-duty reducers, and other large heavy equipment.
