Idler angular misalignment is one of the four main sources of conveyor operating friction. Idlers are equipped with slots allowing angular adjustment as needed for tracking but the optimum position perpendicular to the belt direction is uncertain. Angular triangulation is tedious and requires two millwrights. More importantly, manufacturing variations in the idler frame and conveyor stringers mean conveyor and idler frames are not necessarily good for measuring points.
What is a meniscus tear? A meniscus tear is a common knee injury. The meniscus is a rubbery, C-shaped disc that cushions your knee. Each knee has two menisci (plural of meniscus)-one at the outer edge of the knee and one at the inner edge. The menisci keep your knee steady by balancing your weight across the knee. A torn meniscus can prevent your knee from working right.
