Meridian Laboratory ML6® precision polyurethane hubbed drive rollers, (or friction rollers) are manufactured in cores made of 6061 aluminum or 304 stainless steel but are available in plastics and other non-metallic materials as well.  Precision polyurethane is molded with tolerances of 0.0015” or better, they are available in a variety of standard sizes and custom profiles.  For applications that are space sensitive, see Meridian Laboratory’s complete lineup of precision polyurethane hubless drive rollers.

Custom molded polyurethane roller and drive sizes and profiles are available very affordably, with turnaround times in as little as 5 days.  Meridian Laboratory specializes in delivering high-quality, precision polyurethane drive rollers and wheels – ranging in quantity from 1 to 1M+.

ML6 polyurethane drive wheels are available in a variety of sizes, colors, and durometers to meet any of your requirements. Click here to shop online.

Why Precision Matters

While it’s easy to think “it’s just a roller”, it’s even easier to lose sight of how much you ask of your rollers and wheels, day in and day out. Keeping your operations running with a minimum of downtime for machine repairs, feed jams, tuning of encoder wheels, or other time wasters (and money costers) means upgrading to superior components for your application. If you expect and demand that your equipment do more, ML6 offers a proven upgrade you’ll notice immediately.
