Tapered roller bearing force balance

Tapered roller bearings are separable bearings, miniature ball bearings‍ inner, outer ring has tapered raceway. This kind of bearing rollers according to the number of rows into single row, double row and four row tapered roller bearings and other structures. double direction thrust ball bearing‍ can bear radial load and axial load in one direction. When the bearing radial load, will produce an axial force, so when you need another can bear the reverse direction to balance the axial force bearing
