Ruland MCLC-10-10-F is a one-piece rigid coupling with 10mm x 10mm bores, 29mm OD, 45mm length, and 3mm x 3mm keyways. It has precision honed bores to ensure they are collinear and do not introduce misalignment or vibration into the system making it suitable for high precision servo applications as well as shaft to shaft connections. Proprietary Nypatch® anti-vibration coating on hardware allows for even seating of the screw, repeated screw installations, prevents galling, and maintains high holding power. It eliminates the need to treat screws upon receipt greatly reducing installation time. Forged screws ensure maximum holding power. Tightly controlled bore tolerance of +.050mm/+.012mm is maintained. MCLC-10-10-F is made high grade 2024 aluminium for lightweight and increased screw seating torque. It is machined from solid bar stock.
