Polyurethane Idler Rollers - High Tolerances & Unbeatable Durability

ML6 Precision Polyurethane Idler Rollers & Wheels

Precision Polyurethane Idler Rollers & Wheels

» Non-marking, durable polyurethane coating» Precision dimensional tolerances with low runout
» Bronze bushing self-lubricates to spin freely on shaft» Industry-leading bond strength between ML6 polyurethane and bushing

Meridian Laboratory ML6 precision polyurethane idler rollers can serve as guides, tensioning wheels, or in any application which requires a roller to spin freely on a shaft.  Precision polyurethane ML6 is bonded to an SAE 841 oil-impregnated bronze sleeve bushing, and is ideal for lighter duty applications with low to moderate speeds.  For high speed or heavier duty applications, see our complete line of ML6 precision polyurethane coated bearings.

All of Meridian Laboratory’s ML6 polyurethane idler rollers & wheels feature a cast polyurethane “tire” that is bonded to the core extremely well.  The bond strength of the polyurethane to the idler core itself is stronger than the polyurethane itself.  None of our polyurethane idler rollers are ground to size, guaranteeing both better tolerances (typically 0.0015″ or better), as well as maximum longevity.

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

ML6 polyurethane idler rollers are available in a variety of sizes, colors, and durometers to meet any of your most demanding requirements. Click here to shop online.

Why Performance 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.

In this short video above, discover one (of many) reasons a more durable, precision roller can have a huge impact on your manufacturing environment.
