Idler Sprockets for Metric Roller Chain
Ensure constant tension and reduce wear and vibration on your drive with our high-performance sprockets with built-in ball bearings. These sprockets press against your metric ISO roller chain to maintain constant tension, while rotating freely on double-sealed ball bearings that keep dirt out. Designed for use with roller chain tensioners, these sprockets come with a finished bore that fits directly onto your shaft, eliminating the need for machining. Compliant with ISO 606 international standards for dimensions and materials, our sprockets are built to last and deliver reliable performance. Choose our sprockets for constant tension and reliable performance on your drive.
