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?
- Only manufacturer with precision honed bores on straight bore rigid couplings for superior fit and torque transmission and alignment. Honing corrects any residual distortions caused by stresses introduced during the manufacturing process, resulting in a round, precisely sized bore with both bores being collinear. Proper sizing and geometry assures a larger percentage of shaft contact and greater torque transmission ability.
- Ruland rigid couplings do not introduce misalignment or vibration into the system making them suitable for high precision servo applications and shaft to shaft connections.
- Highest grade forged screws (DIN 12.9 for metric screws) test to or 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. It is a 360-degree visible coating of Nylon on several threads of the socket head cap screws. No additional screw treatment is needed saving time during the assembly process.
- 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.
- Screws are opposing in two-piece styles for a balanced design that reduces vibration and has higher speed capabilities.
- Keyways are available as a standard in two-piece rigid couplings. Step bore combinations including inch to metric are also available.
- Available in a variety of sizes and materials including lead-free steel, stainless steel, and high grade aluminum (for low inertia).
- All Ruland rigid couplings are RoHS3 and REACH compliant.
