Abstract: A stabilizer for vertically driven pumps in which a bearing is supported on the drive shaft approximately half way between the pump and the motor. The stabilizer bearing prevents bowing of the drive shaft which would cause considerable wear on the pump packing resulting in leaks. The stabilizer bearing is supported by adjustable arms each of which have an end which is bent to a 90.degree. angle and then twisted. Each of the ends of oppositely disposed support arms are twisted 90.degree., left and right respectively, after being bent so that the arms will counteract any torque on the drive shaft.
