MOUETTE specializes in precision manufacturing of pins, rollers, dowels, needle rollers, and shafts. Our advanced materials expertise and quality processes ensure components perform reliably at high temperatures, speeds, and loads. We offer custom development for specific applications including CV joints, clutches, and starters.
Bearing grade chrome steel (52100/100Cr6/SUJ2/GCr15) is preferred for superior wear resistance and hardness (HRC 60-65). Stainless steel (400/300 series) provides corrosion protection, while tool steels and specialty alloys offer additional performance characteristics.
Our manufacturing process includes precision cutting, centerless grinding, heat treatment, and finishing operations. We employ 100% inspection for critical dimensions and offer various end configurations including radius, chamfer, and spherical profiles.
