Meridian ML6 Polyurethane Coated Bearings Review: Specs, Price and Applications
Meridian ML6 polyurethane coated bearings start with sealed radial ball bearings, with stainless options, and bond ML6 urethane to the outer diameter or to a machined core.
Runout is as low as 0.0015 in TIR, multiple durometers, sizes and urethane thicknesses are available in SAE and metric, and parts can be molded to a housing or press-fit.
Quick Verdict
Quiet, non-marring rolling contact for guides and conveyors in automation equipment.

Design and Operating Principle
ML6 is Meridian Laboratory's proprietary polyurethane compound, valued for abrasion resistance, tear strength, flexibility, chemical resistance and bond strength. Parts are precision molded to final dimensions in-house, usually without grinding or post-machining, and Meridian's mold library often avoids extra tooling charges.
Bonding the polyurethane directly to the core, rather than gluing a sleeve on, resists delamination and tear-off under high load and high cycle counts. Precision molding achieves total indicated runout as low as 0.0015 in, which keeps contact pressure even as the part rotates.
Integration and Selection
Choose bearing size, urethane thickness and durometer for load and traction. Press-fit or mold into housings.
Use stainless bearings in washdown areas.
