Polyurethane Hubbed Drive Rollers | Tight Tolerance Polyurethane Drive Wheels

Hubbed Polyurethane Drive Rollers & Wheels

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 which 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.
