"door wheel" is not in Webster. When I read this EDICT definition, I could only think it 
might mean the wheel on the hatch of a submarine.

Three definitions of "door roller" ~

1) http://www.merriam-webster.com/dictionary/door roller
a wheel or roller supporting a sliding door usu. running on a door track

2) http://www.dictionaryofconstruction.com/definition/door-roller.html
The operational hardware used primarily on heavy doors, such as refrigeration doors, to 
allow them to roll.

3) Google ("define:" function)
(Door Rollers) Two sets of tandem steel wheels with ball bearings for smooth operation. 
Usually found on sliding patio doors.

* The following two pages say it can mean "sash roller" as well, but I can't confirm that. 
戸 generally means "door", whereas a sash roller is used in a sliding *window*. But it may 
be true, nevertheless.
