Standard sizes are available in cores made of 6061 aluminum or 304 stainless steel, but are offered as well in plastics and other non-metallic materials.  Meridian Laboratory’s ML6 hubbed polyurethane drive rollers and wheels are molded with tolerances of 0.0015” or better, they are available in a variety of standard sizes and custom profiles as well.  Also see our complete lineup of hubbed drive rollers.

Custom sizes and profiles are available very affordably, with turnaround times in as little as 5 days.

ML6 polyurethane drive wheels are available in a variety of sizes, colors, and durometers to meet any of your most demanding 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.
