RC-050-KW Black Oxide Mild Steel Rigid Coupling 1/2″ Bore 1″ OD

Description

Product Overview

The RC-050-KW rigid coupling is engineered from high‑grade mild steel that has been black‑oxide plated to provide a durable, corrosion‑resistant surface. Designed for power transmission systems, this coupling offers a 1/2″ bore and a 1″ outside diameter, delivering a compact yet robust solution for aligning shafts and transmitting torque. The component measures 1‑1/2″ in length, providing sufficient engagement while maintaining a low profile for tight installations. A 1/4‑20 x 1/4″ set screw secures the coupling in place, allowing for quick assembly and disassembly without the need for extensive system shutdowns. Tolerance is tightly controlled at +.0005/+.0025, ensuring consistent performance across a range of operating conditions. The black oxide coating not only enhances aesthetic appeal but also adds a layer of protection against moisture and chemicals, extending the service life of the coupling in harsh industrial environments.

Usage

This rigid coupling is ideally suited for a broad spectrum of industrial applications, including conveyor systems, gearboxes, pumps, and motor‑driven equipment. Its design accommodates both continuous and intermittent operation, making it a reliable choice for manufacturing lines, material handling facilities, and processing plants. The coupling’s compact dimensions allow it to be installed in confined spaces where larger, more complex couplings would be impractical. Engineers and maintenance technicians appreciate the ease of installation: the set screw can be tightened with standard tools, and the precise bore alignment reduces the need for additional shims or adjustments. The product performs well under varying loads, from light torque requirements to heavier duty scenarios, thanks to the inherent strength of the mild steel core and the protective black oxide finish.

FAQ

What size shafts can this coupling accommodate?

The RC-050-KW is designed for shafts with a 1/2″ bore. It fits standard 1/2″ diameter shafts commonly used in industrial power‑transmission applications.

Is the black oxide coating sufficient for outdoor or wet‑environment use?

While the black oxide finish provides a level of corrosion resistance suitable for most indoor industrial settings, for highly corrosive or continuously wet environments, additional protective measures such as sealing or a secondary coating may be recommended.

Can the set screw be replaced with a different fastener if needed?

The coupling is engineered for a 1/4‑20 x 1/4″ set screw. Using a fastener with the same thread size and length is acceptable, but alternative fasteners should be approved by the manufacturer to maintain proper torque and alignment.

What is the recommended torque for tightening the set screw?

Climax recommends tightening the set screw to a torque of approximately 2‑3 Nm (Newton‑meters). This ensures a secure fit without overstressing the screw or the coupling body.

How does the tolerance of +.0005/+.0025 affect installation?

The tight tolerance range minimizes axial and radial play between the coupling and the shaft, resulting in smoother operation, reduced vibration, and longer component life. It also simplifies alignment during installation, as fewer adjustments are required.
