Polyurethane Coated Bearings Model Specifications

» Non-marking, durable polyurethane coating» Reduced wear and increased longevity of contact surfaces
» Reduced noise while rotating» Improved traction against contact surfaces

Meridian Laboratory ML6 precision polyurethane coated bearings are extremely precise and durable.  Designed with heavy-duty and higher speed ratings in mind, they are non-marking and have a low T.I.R.  For light-duty applications with moderate to low speeds, see our complete line of ML6 polyurethane idler rollers.

Contrary to other manufacturers of polyurethane bearings who rely on a polyurethane tire slipped over the bearing race, Meridian Laboratory molds and bonds polyurethane directly to the race.  In fact, the bond between the molded polyurethane and the bearing race is stronger than the ML6 polyurethane itself, guaranteeing a strong bond and durable, long-lasting polyurethane bearings – with unbeatable precision and tolerances.

Custom sizes and profiles are available very affordably, with turnaround times in as little as 5 days.  Metric sizes are not listed, but available by request.

ML6 polyurethane coated bearings 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.
