Question:
Is the Bulldog BD500199 a ball screw design? I did not see it printed anywhere like other ball screw type jacks.

The Bulldog Powered Drive Trailer Jack - Drop Leg - A-Frame - 22" Lift - 4,000 lbs - Black # BD500199 uses an ACME screw, not a ball screw. An ACME screw uses a trapezoidal shape thread to roll onto the lead screw and does not use ball bearings.
