Climax Metal Products 2ISCC-137-100-S Rigid Shaft Coupling

Product Description

The CLIMAX METAL PRODUCTS 2ISCC-137-100-S is a two-piece rigid shaft coupling designed to connect two shaft ends in a fixed, non-flexible configuration. With a 1.375-inch inside bore diameter and a 2.5-inch outside diameter, this coupling clamps securely around mating shafts without the need for a keyway. Constructed from stainless steel, it is well suited for environments where corrosion resistance is a priority. The split two-piece design allows installation without disassembling the surrounding drivetrain, making it a practical choice for industrial maintenance technicians and mechanical contractors working on shaft alignment applications.

This coupling is used in mechanical power transmission systems where two shafts must be joined rigidly and held in precise angular and axial alignment. Typical applications include HVAC fan assemblies, pump drive systems, and light industrial equipment. The absence of a keyway simplifies installation on smooth shafts, relying on clamping force alone to transmit torque. It is appropriate for both new equipment builds and field replacements where the original coupling must be swapped without major disassembly.

Key Features

• Two-piece split design allows installation and removal without full shaft disassembly
• 1.375-inch inside bore diameter fits corresponding shaft size without a keyway
• 2.5-inch outside diameter in a compact rigid profile
• 3.625-inch overall length provides sufficient clamping surface for secure shaft engagement
• Stainless steel construction offers corrosion resistance in demanding environments
• Rigid coupling design maintains strict shaft-to-shaft alignment with no flex or misalignment compensation

Compatibility

Designed as an OEM-style replacement or direct-fit rigid shaft coupling for mechanical power transmission applications requiring a 1.375-inch bore two-piece clamp style coupling without a keyway.

Installation Notes

Installation should be performed by a qualified mechanical technician or industrial maintenance professional. Shut down and lock out all power to the drive system before installing or removing the coupling. Ensure both mating shaft surfaces are clean, free of burrs, and within the specified bore tolerance before tightening the clamping fasteners. Rigid couplings do not compensate for shaft misalignment, so precise axial and angular alignment must be confirmed before final torque is applied to the clamping hardware.
