23022/W33

23022/W33 is a self-aligning roller bearing with enhanced lubrication design. Its core function is to be suitable for equipment in industries such as elevators, wind power, and mining that "require continuous lubrication, bear heavy loads, and may have misalignment of the axis" (such as the main shaft of a fan, the transmission shaft of a screening machine). Based on the high load-bearing and self-aligning advantages of the 23022 base model, it achieves long-term supplementary lubrication through an annular oil groove on the outer ring and three oil holes ("W33"), which can reduce friction and wear, adapt to complex working conditions, and ensure the stable operation of the equipment in heavy-load and vibration scenarios.
