In order for the door stoppers to last longer, they must be properly lubricated. Choosing the wrong lubricant can lead to accelerated wear of the mechanism and extraneous noise when the stopper is operating.
❎ What lubricants should not be used?
Do not use silicone, lithium and consistent lubricants (lithol, solidol), as they can negatively affect the operation of the stopper:
— These lubricants collect dust and dirt, forming an abrasive that accelerates the wear of the rod and inserts.
— Liquid compounds reduce the fixation of the door
— the lock simply slides along the rod, without lingering in positions, which leads to the disappearance of the fixation.
— WD-40 is not a lubricant!
✅ What lubricant is suitable?
To increase the service life of the locks in the door stopper, it is recommended to use oil with molybdenum disulfide. Molybdenum-based plastic lubricants form a film that serves as a layer of dry lubricant even after the dispersion medium has evaporated, thus lubricating friction units even in emergency conditions and with sudden temperature changes.
— Molybdenum disulfide forms a stable antifriction film that significantly reduces unit wear.
— The film protects metal surfaces from moisture and prevents rust.
— The oil does not attract dirt and dust, thereby eliminating the formation of an abrasive layer.
— Wide range of operating temperatures: the lubricant remains effective both in winter and in summer.
Our repair kits for door limiters always contain the required amount of special lubricant with molybdenum disulfide. Using oil with molybdenum disulfide will ensure reliable fixation of the door, reduce limiter wear and extend its service life!
