Climax Metal Products RC-050-KW Rigid Coupling Keyway

Product Description

The CLIMAX METAL PRODUCTS RC-050-KW is a set screw rigid coupling designed for positive shaft-to-shaft connection in mechanical drive and motion control applications. Machined from mild steel, this coupling features a 0.5 inch bore and a 1 inch outside diameter, with an overall length of 1.5 inches. A 0.125 inch wide by 0.0625 inch deep keyway is machined into the bore to accept a standard key, preventing rotational slip between the shaft and coupling. Set screws lock the coupling firmly onto the shaft once the key is seated. Licensed mechanical technicians, millwrights, and industrial maintenance professionals are the typical installers.

This coupling is suited for inline shaft connections where minimal misalignment is expected and positive torque transfer is required. The keyway drive is especially useful in pump, conveyor, fan, and light machinery applications where shaft rotation must be positively locked without relying on friction alone. The RC-050-KW belongs to the RC series from CLIMAX METAL PRODUCTS and ships as a single unit. It is appropriate for both original equipment builds and field replacement of worn or damaged rigid couplings in similar shaft configurations.

Key Features

• 0.5 inch bore accommodates standard half-inch shafting
• Keyway machined to 0.125 inches wide by 0.0625 inches deep for positive rotational lock
• Mild steel construction provides adequate strength for light to medium duty applications
• Set screw retention secures coupling axially and radially on the shaft
• 1 inch outside diameter and 1.5 inch length suit compact drive arrangements
• RC series design offers straightforward inline shaft coupling without flexible elements

Compatibility

Designed as an OEM-style rigid coupling for inline shaft connections requiring a 0.5 inch bore with a standard 0.125 inch by 0.0625 inch keyway. Verify shaft diameter, keyway dimensions, and torque requirements before installation.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician following applicable machinery safety standards. De-energize and lock out the drive equipment before removing any existing coupling or installing this part. Ensure the shaft key fits the keyway without excessive play before tightening set screws, and confirm shaft and bore surfaces are clean and free of burrs. Do not use this rigid coupling to compensate for shaft misalignment, as rigid couplings require careful shaft alignment prior to final assembly.
