Polyurethane Coated Yoke Rollers / 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 polyurethane coated yoke cam followers (otherwise referred to as yoke rollers) are available in the same sizes as our studded cam followers, however, they feature a thru-bore rather than a threaded shaft. All Meridian Laboratory ML6 polyurethane coated yoke rollers are American-made with high-strength steel (available in stainless steel), and are sealed with ports located inside the bore for relubrication of the bearings ensuring maximum longevity.

ML6 Precision Polyurethane yoke rollers feature a smooth, quiet operation with better traction and abrasion resistance over nylon and other coverings. ML6 polyurethane is non-marking and will help protect the surface that the rollers ride on from wear and tear.

They 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.
