The slide bearings mainly consist of bearings which help them to slide easily. So they had a beam that helped support the slide so it could be moved easily without disturbance. They are usually lightweight, so they must not make any noise. These bearings are made of resin as their surface is a bit slippery, so they must not get stuck in the middle and operate smoothly.
Mainly these slide bearings (ลูกปืนสไลด์, which is the term in Thai) are used these days in apartments and complexes as well, as it is easy to open and close as well. Once it closes, it automatically locks itself so nothing can open it from outside. Previously these facilities were not there, so people faced many problems. Due to rain, the wooden panes typically swell a bit, which was a strenuous job to close the window. Sometimes in the middle of the night, if a storm struck the ground, then a gush of wind would open it. So these things are negligible in these slide bearings. Now it depends upon the quality; low-quality items don’t last forever.
Not that slide bearings are used chiefly in the window panes. People have used it in drawers, almirah, and doors. In the modular kitchen, the drawers contain bearing, so it is easy to close them when you are in a hurry and doesn’t cause any obstruction. Doors are also as easy as the window panes, and there is a knob which will help you to lock them.
There is one problem with using this slide bearing if any of the drawers got stuck in the middle and were unable to remove from their place, then a mechanic can fix it by opening all the joints of the drawer. Banging the drawers or windows hard can also cause damage to the bearings. The drawers were previously seen to come outside the socket, but in slide-bearing drawers, the drawer will stop preventing it from falling up to a particular moment.
So try to buy an anti-corrosion bearing; a steel body must be there to prevent splitting. So the accumulation of dirt can be seen in that shaft, so it’s a bit tough to clean. Through proper equipment, all the dirt must get cleaned off. If a noticeable crack is seen on the surface, they will replace it with another slide.
