Polyurethane Tubing and Belts Model Specifications

» High friction, non-marking material	» Round, flat, intricate shapes and profiles
» Available in variety of colors and durometers	» Perfect (no grinding) surface finish

Coated rollers and shafts are not the only polyurethane products that Meridian Laboratory specializes in. We also manufacture stand-alone polyurethane tubes, belts, and other products without a core or bonded material.

The same high friction, precision tolerance, and high wear polyurethane that we mold as precision drive wheels can be produced into a low-cost, coreless polyurethane tube. Polyurethane tubes are an economical solution to adding a non-marking, durable, coating to an existing shaft or product. This is an excellent way to add part protection to conveyor rollers and drive rollers without the added expense of a coated roller. ML6 polyurethane tubes can be easily pressed onto shafts, and when worn easily removed and replaced. These tubes are made with the same ID and OD tolerances as our rollers (+/-0.001”), with a perfect surface finish and no grinding. ML6 tubes can be made to any size ID/OD and are always cut to length for your application, up to 30” in length.

About
Options

ML6 polyurethane belts are a great alternative to the traditional poly cord. We manufacture belts to exact circumferences in any width for your specific application. ML6 belts offer the same great friction and low wear benefits, but without the drawback of having a weld seam. Meridian Laboratory belts are seamless and can be used at much higher tension than typical belts. This combined with the high friction characteristic of ML6 polyurethane provides for greater friction and less slippage in the mechanism.

Many customers also use precision polyurethane ML6 for applications which are not traditionally a tube or a belt, but simply as a non-marking and durable material that is highly customizable, providing low volume, cost-effective solutions. Customers often use polyurethane ML6 as a gasket, seal, or bumper material including flat, round, and other shapes and profiles.
