TL;DR
A roller stem is the steel shaft of a garage door roller that slides into the door's hinge sleeve or end bracket, carrying the wheel that rides in the track. Stems come in 4-inch standard and 7-inch lengths for end hinges and low-headroom setups, paired with nylon or steel wheels of 10 or 13 ball bearings.
What it means
A roller stem is the steel shaft of a garage door roller that slides into the door's hinge sleeve or end bracket, carrying the wheel that rides in the track. Stems come in 4-inch standard and 7-inch lengths for end hinges and low-headroom setups, paired with nylon or steel wheels of 10 or 13 ball bearings. Worn ones let the wheel wobble and bind, producing the grinding and popping that precede a door jumping its track—rollers are replaced as a set during tune-ups.
