Industry Information

Plastic Linear Bearings

Plastic linear bearings allow objects to move smoothly along in a straight direction with a minimum of friction. Made solely from plastic, these bearings are able to withstand the same rigors that ceramic or steel bearings can, and many manufacturers offer plastic versions of precision, miniature, linear rotary and pillow block bearings. Plastic has certain advantages over the more traditional materials, like being corrosion resistant to chemicals and acids that would harm conventional bearings.

One type of plastic linear bearings, the plastic ball bearings are not easily nicked or scratched and will not dent their housing like metal would. Plastic is up to five times lighter than steel, which reduces the energy required to move the bearing. It is relatively inexpensive, and new designs can be made quickly by a mold tool. Magnetic distortion can be eliminated by using certain plastic ball bearings, and plastic automatically reduces noise and vibrations. Lubrication is not necessary because the interaction of plastic and stainless steel has a low coefficient of friction. Because of these characteristics, plastic linear bearings are used in the printing, textile, manufacturing, pharmaceutical and medical industries as well as in environments with salt water, around film processing solutions, in clean rooms, small engines, electronics and on robotic assembly lines.

Plastic linear bearings, like the variety of general linear bearings, are usually cylindrical in shape with open ends or rectangular with a carriage that runs in a V shaped groove. They are available in a variety of sizes, ranging from a few millimeters in inner diameter to centimeters according to the metric system; bearings measured in U.S. customary units are prevalent as well. There are two main categories of linear bearings, those that roll and those that slide. Rolling element bearings contain small balls that rotate and travel along tracks, called raceways. The ball bearings provide smooth, low friction movement that is repeatable, rigid and accurate. Plane bearings do not employ spherical elements and instead bring surface areas into contact with each other, requiring smooth surfaces and lubrication. Plastic linear bearings are available in the same configurations. Bearing housings and carriages made of plastic are increasingly common, but plastic ball bearings are also becoming important in certain applications. Plastic ball bearings offer high acceleration speeds, quick start-and-stop abilities and increased resistance to damage and wear over time. Plastic bearings that slide without the use of rolling elements have similar benefits. Because there is no metal to metal contact involved with a plastic linear bearing, there is less friction and heat that would slow movement.
