Calculation of the allowable load for Type B supported bearings

Type B support; I couldn’t find this symbol. What does the latter one mean? Was it written wrong? It should be. After repeated calculations of my own, I solved the case. B2 should be B2; the unit resulting from this formula is N, and by dividing that by 1000, we get KN in the table. I hope this will be helpful to students who encounter this problem in the future.
You can refer to the formulas in Chapter 7 of NB/T 47003.1-2022 to check; the definition for 47065 seems to be incorrect
I would like to ask how to determine the reduction factor k? Thank you first
