Request a Quote
For the working conditions which only support radial load, we recommend you use 7300B series single-row angular contact ball bearing provided by SHANDONG GUANXING in paired. In addition, if the thrust load is overloaded, you can also connect multiple 7300B series single row angular contact ball bearings in series.
