Selection of bearings for submersible pumps

When selecting angular contact bearings for submersible pumps, should type A or type B be used?

A: indicates a contact angle of 30°; B: indicates a contact angle of 40°； C: Indicates a contact angle of 15° ； AC: Indicates a contact angle of 25°. The larger the contact angle, the greater the inclination, and the greater the axial force it can withstand. AC is more commonly used in ordinary horizontal pumps. The contact angle depends on the direction and magnitude of the applied force; the larger the contact angle, the stricter the control of the clearance at the bearing cover must be
It depends on the pump’s parameters; for higher flow rates, a larger contact angle is preferred, taking into account the answer from the first floor.
