Single row spherical roller bearing and double row spherical roller bearings have what different?
At the same size of the outside diameter, the biggest difference is that the bearing capacity is different, and the single row is larger than the double row.
Single row self-aligning roller bearings, outer ring raceway is spherical and the inner raceway of the force center line (pressure line) parallel to the width of the middle plane. Of course, the carrying capacity of the double row is larger than that of the single row
Double row spherical roller bearing outer ring raceway is spherical, the inner ring of double raceway (two ball raceway force through the center line of the outer ring raceway), each raceway force center line and the bearing width of the middle plane at a sharp angle of pressure angle of 10 degrees.
