A disk spindle motor having a permanent magnet central shaft. A pair of annular, non-magnetic combination thrust and journal bearings having truncated-conical outer surfaces are spaced apart on the shaft. The bearing coact with complementary surfaces of the hub of a motor rotor. Shaft end caps connect the shaft to base means and have radially extending shoulders which define annular gaps with the rotor and function as ferrofluidic seals.
