Lifetime Standard Ball Bearing Roller Offered
Martin Door is introducing the first standard maintenance free ball bearing roller in the garage door industry.
The new roller, available in the first quarter of 2004, includes a front and back seal on the bearing, which eliminates maintenance on the roller and is the first of its kind in the garage door industry.
|Martin Door Manufacturing is introducing a new sealed bearing as part of every Martin garage door, beginning next year. David Martin shows off a prototype of the new roller.
"Our industry is sure to follow," Dave Haslam, director of marketing and sales for Martin Door Manufacturing said of the new sealed bearing.
The sealed bearing irons out a wrinkle brought on by a previous Martin Door innovation. With the advent of the Roller Shield™ in 1998, it became difficult to lubricate the roller. The new seal over the bearing will keep out dust, water, sand and other material. It creates what Martin Door CEO David Martin describes as a "lifetime greased ball bearing roller."
The bearings on Martin Door rollers are packed in synthetic grease that adapts itself to the severity of climate change without any change in consistency. The new seal provides a lifetime for that selling feature.
The roller was already distinct before the most recent change. The roller used on Martin Doors has 11 ball bearings to increase its longevity and quiet operation. The high quality hard ball bearings are self-contained in a hardened steel race. The tire on the roller is made of Delrin™, a polymer substance, especially made for Martin by Dupont.
