As the aircraft was taxiing to the gate by terminal "l", the pilot requested emergency equipment, due to a smoking left main gear. Aircraft was stopped just off the taxiway, passengers were deplaned through the normal passenger entry door at the rear of the aircraft. Emergency equipment responded, no evidence of fire. There was no emergency evacuatuion of this aircraft. The aircraft's #1 main tire (lt. outbd) was blown and this same axle area had damage from the wheel bearing coming apart. The tire had evidence of hydraulic fluid that came from the brake assembly. Maintenance had trouble removing the #1 wheel due to parts being welded to the axle. The inboard bearing (large bearings) were disfigured from heat and friction. Maintenance changed the left main landing gear. Sima maintenance director dan maddy reported the wheel had been installed for 2 months and had 390 cycles (average has been 900), also suspect a bearing failure. Note: it was also reported this is the third reported bearing failure on an outbd axle. The pmi was briefed and a follow up will be done by the sima cmu.
