Light-duty conveyor rollers tend to be generally made of plastic-type material and aluminum, but may also be constructed of steel. Additionally they practically often utilize on non-precision bearings, that are most suitable intended for very low and moderate speed conveyor systems. Keeping that in mind, it really is essential to note that light-duty rollers should not only have light-weight to modest loads however ought to also exclusively be utilised for functions which isn't going to demand increased speed. The dimension of light-duty rollers include 1 ? in . to two.5 in ..

Medium-duty rollers frequently make use of semi-precision or precision bearings, however a few actually use commercial grade stainless steel bearings. Those that use commercial quality stainless steel bearings tend to be usually used for conveyors which are positioned in extremely corrosive places. Semi-precision and precision bearings might be chosen for functions which involve higher rates of speed, with semi-precision bearings for those that need to have up to a maximum of four hundred rpm, with precision bearings with regard to anything quicker than that.
Heavy-duty rollers - Heavy-duty rollers are just about the most durable kinds of conveyor rollers. With roller diameters covering anything from three.five ins to 7 inches, and roller tubes with thickness ranging from zero.3 to zero.5 inches, these types of conveyor rollers can easily move really weighty loads with no difficulty whatsoever.

In case you're unsure if you'll need a light, medium, or perhaps heavy-duty roller, what you may do is determine exactly what the weight is of the heaviest merchandise or load you foresee for the rollers to transport. A very good guideline is always to add 25% to this figure to find out your load capability of your roller conveyor you are going to be in need of.
