23088K

23088K is a double-row self-aligning roller bearing with an inner diameter of 440mm, an outer diameter of 650mm, and a width of 157mm. Its core function is to be suitable for the installation scenarios of heavy-duty low-speed and heavy-load equipment, with the inner ring (K) having a 1:12 taper to achieve a stable interference fit with the cone shaft/retaining sleeve. It relies on the spherical roller structure to provide excellent automatic self-aligning capability, which can compensate for the angle deviation and misalignment of the shaft and the bearing housing. It also has high load-bearing performance of 3830kN for dynamic load and 6550kN for static load. It has a rotational speed adaptation capability of ≤430r/min for grease lubrication and ≤530r/min for oil lubrication. It is mainly used for key parts support in industries such as metallurgy, mining, building materials, ports, power, and heavy machinery manufacturing, addressing the high load, vibration shock, installation deviation, and long-term stable operation requirements in low-speed heavy-load conditions. It is a core bearing selection scheme for heavy equipment that combines centering compensation and heavy-load bearing capabilities.
