About
One-piece rigid couplings from Ruland do not mar the shaft and have high torsional holding power. They are supplied with proprietary Nypatch® anti-vibration coating, which allows for repeated installations, prevents screws from coming loose during operation, and provides the necessary dissimilar material in stainless steel couplings to reduce galling. Straight bore rigid couplings from Ruland are precision honed to ensure bores are collinear. This is important when the rigid coupling is used in a precision servo system as honing allows for greater surface contact with the shaft and higher torque transmission capabilities. Ruland manufactures one-piece rigid couplings in 1215 lead-free steel with a proprietary black oxide finish, 303 stainless steel, and lightweight 2024 aluminum.
Two-piece rigid couplings have the same benefits as one-piece style with the added advantages of being serviced in-place, opposing hardware for a balanced design and step bores with keyways. They are supplied with proprietary Nypatch® anti-vibration coating, which allows for repeated installations, prevents screws from coming loose during operation, and provides the necessary dissimilar material in stainless steel couplings to reduce galling. Straight bore rigid couplings from Ruland are precision honed to ensure bores are collinear. This is important when the rigid coupling is used in a precision servo system as honing allows for greater surface contact with the shaft and higher torque transmission capabilities. Ruland manufactures two-piece rigid couplings in 1215 lead-free steel with a proprietary black oxide finish and 303 stainless steel.
Set screw rigid couplings from Ruland have precision honed bores to ensure they are collinear. This is important when the rigid coupling is used in a precision servo system or on a mixer as honing allows for greater surface contact with the shaft and higher torque transmission capabilities. Ruland manufactures set screw rigid couplings in 1215 lead-free steel and 303 stainless steel.
Short rigid couplings can be used in applications where space is limited. The short rigid coupling has a reduced torque capability compared to a standard rigid coupling due to its use of a single socket head cap screw per shaft. However, the compact size of the collar reduces inertia making it ideal for motion control applications. Ruland manufactures short rigid couplings in 1215 lead-free steel with a proprietary black oxide finish, 303 stainless steel, and high-strength 2024 aluminum. Bore sizes range from 1/8" to 2" and 6mm to 25mm.
Why Ruland?
- Lower installation costs based on our proprietary Nypatch® coated hardware. This also allows for increased holding power and multiple screw insertions without screws loosening during operation.
- Enhanced holding power, improved corrosion resistance, and a fine glossy finish are achieved through our in-house proprietary black oxide process.
- Designed for reduced vibration and higher speed capabilities, our two-piece styles feature opposing screws, ensuring a balanced design.
- A fine, burr-free finish for environments where cross-contamination is not desirable.
- The highest performance and precision are achieved through careful manufacturing processes in our Marlborough, MA advanced manufacturing facility.
- Superior fit and torque transmission due to precision honing of the bores on straight bore rigid couplings, which ensures collinearity.
- True ratings based on actual testing.
