Description
Only manufacturer with precision honed bores on straight bore rigid couplings for superior fit and torque transmission and alignment. Ruland rigid couplings do not introduce misalignment, vibration, or bearing noise into the system making them suitable for high precision servo applications and shaft to shaft connections. Highest grade forged screws test beyond industry standards for maximum torque ability. Proprietary Nypatch coating on hardware provides even seating of the screw, repeated screw installations and prevents galling. Nypatch hardware also resists vibration and maintains holding power. In-house proprietary black oxide process produces a fine glossy finish while increasing holding power and resisting corrosion. The cross cut design ensures a proper clamp on both shafts because it can accommodate slight deviations in the size of the shafts being connected. All rigid couplings are manufactured from bar stock in our Marlborough, MA factory under strict controls using proprietary processes.
