If you have a revolving door at the entrance of your business, then this door is a bit more complicated than a regular hinged door. This means that it needs a bit more maintenance than a traditional front door. If you want your door to work well without any issues, then keep reading to learn about a few maintenance tasks you should perform.

Inspect The Bottom Sweep

Your revolving door will have several doors that are connected in the middle. Each door will connect to a central post and to attachments that sit along the ceiling. The doors will not connect to the floor, because debris can catch along the bottom door edges and prevent movement. Instead, sweepers are installed to help move debris out and away from the doors, and they are installed along the small gap underneath them. 

Sweepers are either nylon, polyester, or polypropylene brushes or vinyl or rubber strips. Inspect the sweepers carefully for damage and replace them if you notice any cracks, breaks, or missing brush bristles. Purchase sweepers from your local revolving door specialist that are the same size and width as the ones currently installed. Sweepers sit in small channels on the bottom edge of each door. To remove the old sweeper, move the edge of the door to the open doorway and look for a small end that keeps the sweeper in place. Remove the screw that keeps the end secured and pull out the old sweeper. Slip the new sweeper into the channel and replace the cap.

Grease The Door

The revolving door will secure into a base called a ceiling canopy, and a circular part sits in the middle of the canopy. This part is called the pivot bearing and it allows the revolving door to spin. Specifically, the bearing will have an open track that holds the doors and lets them move in a circular path around the bearing. If you want the doors to keep moving, then you will need to grease the bearing on occasion. 

Purchase an all purpose or lithium-based grease and place a small amount in the bearing track. Do this every few months to keep movements smooth. Also, when you grease the door, make adjustments to door speed by twisting the speed control screw. This screw sits on the outside of the bearing and it makes it easier or harder to spin the revolving door. Adjustments should be made depending on the season. For example, a slow spinning door is best in winter to keep patrons from slipping on accumulated ice as they enter your business.
