Types of rollers used on roll up sectional garage doors and overhead doors.
Sectional Garage Door Roller Replacement:
A roll up sectional garage door uses rollers, hinges and tracks to operate the door. Along with the spring and cable system to balance the door and guide the movement without exess stress on the components. The number of rollers used on one door will vary on how many panels the door is constructed with. (Example) A four panel garage door will require 10 rollers, A 5 panel door will require 12 rollers. When purchasing rollers, you will find that there are a few choices to pick from, determining quality and noise factor. Replacing steel rollers with vinyl or vinyl coated rollers will reduce the sound of the roller running along the track. Also the length of the roller stem is available in 4", 5", 7" & 9" depending on the design and construction. Here are a few examples of rollers available for replacement.
2" Nylon roller with 4" stem
2" 11 ball bearing nylon coated roller with 4" stem
2" 11 ball bearing nylon coated with 7" stem
2" 13 ball bearing nylon coated with 4" stem
2" 13 ball bearing nylon coated with 7" stem
2" 7 ball bearing steel with 4" stem

IMPORTANT NOTE: Never remove the BOTTOM FIXTURES or fasteners on a sectional garage door with the spring fully loaded. The cables are attached to the bottom fixtures and may cause severe damage and throw the balance of the spring off.
All other rollers can be easily replaced by simply removing the bolts or lags holding the hinge down, pulling the hinge out of the track and relplacing the roller, then reinstalling the roller back to the hinge and to the track. Rollers hinges and tracks can be lubed with a silicon or recommended spray lube for proper functioning. Grease is not recommended on these components. Be careful not to spray inside the roller where the bearings are located. This will wash out the factory grease and cause the roller to wear out sooner.
