1-1/4″ Solid Shaft Coupler with Keyway Set Screws SpinCo C1018 Steel

Description

Product Overview

The 1-1/4″ solid shaft coupler with keyway and set screws from SpinCo is engineered for high‑performance power transmission in demanding industrial environments. Crafted from C1018 mild steel, the coupler receives a durable black oxide finish that enhances corrosion resistance while maintaining a sleek, professional appearance. Its precise 1/4″ x 1/8″ keyway ensures a secure fit with matching shafts, and the 2-1/8″ outer diameter provides a robust interface for torque handling. The overall length of 4-1/2″ and a set‑screw spacing of 1″ allow for straightforward installation and alignment, reducing downtime during maintenance. Designed to meet the rigorous standards of the rigid set‑screw coupling category, this component offers consistent performance, minimal backlash, and long‑term reliability for a wide range of machinery.

Usage

SpinCo’s 1-1/4″ solid shaft coupler is ideally suited for motor‑driven equipment, conveyor systems, gearboxes, and pump assemblies where precise shaft alignment and torque transfer are critical. Its robust construction makes it a reliable choice for heavy‑duty applications such as manufacturing lines, material handling equipment, and agricultural machinery. The coupler’s keyway and set‑screw design enable quick disassembly for routine inspection or replacement, supporting preventive maintenance programs. Additionally, the black oxide coating helps mitigate wear in environments exposed to moisture, chemicals, or abrasive particles, extending service life and reducing the need for frequent part swaps. Engineers and maintenance technicians appreciate the straightforward installation process, which requires only standard hex wrenches and a minimal set of tools, making it an efficient solution for both new builds and retrofit projects.

FAQ

What size shaft does this coupler fit?

The coupler is designed for a 1-1/4″ bore, meaning it fits shafts with a diameter of 1-1/4″ (31.75 mm). The keyway dimensions of 1/4″ × 1/8″ accommodate standard key sizes for secure torque transmission.

Can this coupler be used in high‑speed applications?

Yes, the rigid set‑screw design and precise keyway alignment make it suitable for high‑speed operations, provided the operating speed does not exceed the limits specified in the manufacturer’s technical data sheet. Proper lubrication and alignment are essential to maintain performance at elevated speeds.

How does the black oxide coating affect performance?

The black oxide coating primarily serves as a corrosion‑resistant layer that also reduces surface friction. It does not significantly alter the mechanical properties of the steel but helps protect the coupler from rust and wear, especially in humid or chemically aggressive environments.

What tools are required for installation?

Installation typically requires a standard hex wrench or socket set to tighten the set screws to the recommended torque value. No specialized equipment is needed, and the process can be completed by most maintenance personnel familiar with basic mechanical assembly.

Is there a warranty or guarantee for this product?

SpinCo offers a limited one‑year warranty covering material defects and workmanship errors. Customers can contact our support team with the product serial number and purchase details to initiate a warranty claim or request replacement parts.
