Nuline Idler/Tensioner Pulley EP218

All engine pulleys incorporate ball bearings that run at very high revolutions relative to engine speed. Increasing belt load and exposure to dirt or moisture accelerate bearing wear. All ball bearings used in Nuline Idler/Tensioner Pulleys are from OEM manufacturers and feature C3 rated high-speed races, high-temperature lubricant and heavy-duty silicone seals for maximum service life at high revolutions.
