23948

The bearing model 23948 is a self-aligning roller bearing. Its core function is to provide reliable heavy-load support for equipment with installation errors or shaft deflection. It features double-row rollers, with one common spherical raceway on the outer ring and two raceways on the inner ring that are inclined at an angle relative to the bearing axis. This structure enables it to have automatic self-aligning performance, which can automatically adjust the eccentricity caused by installation errors between the shaft and the bearing housing or shaft deflection. As long as the centerline difference between the outer ring and the inner ring does not exceed 1° - 2.5°, the bearing can still operate normally. At the same time, the bearing model 23948 can withstand large radial loads and bidirectional axial loads, especially suitable for equipment that bears heavy loads and impact loads, such as machine tool spindles. Its inner diameter is 240mm, outer diameter is 320mm, and thickness is 60mm. The rated dynamic load and static load of different brands vary slightly. Taking the NTN brand as an example, its rated dynamic load is 565kN, and the rated static load is 1190kN. When lubricated with grease, the allowable rotational speed is 840rpm, and when lubricated with oil, the allowable rotational speed is 1300rpm.
