Overview
The Climax RC-050-A is a rigid set screw coupling engineered for direct shaft-to-shaft power transmission in industrial and machinery applications. Manufactured from durable aluminum, this coupling combines lightweight construction with proven torque-handling performance. The RC series set screw design delivers cost-effective reliability without sacrificing accuracy or assembly simplicity.
Key Features
- Aluminum construction—lightweight and corrosion resistant
- One-piece rigid coupling design for precise alignment and zero backlash
- Dual set screws (1/4-20 x 1/4) for secure shaft grip and vibration resistance
- Precision-machined bore and OD to close tolerances
- No keying or keyway required—simple installation and removal
- Suitable for moderate torque and speed applications
