Climax Part CC-112-112-KW Mild Steel, Black Oxide Plating Clamping Coupling, 1 1/8 inch X 1 1/8 inch bore, 2 1/8 inch OD, 3 1/4 inch Length, 1/4-28 x 3/4 Set Screw

Description

Product Overview

The Climax Part CC-112-112-KW is a precision‑engineered rigid clamp‑on coupling designed for demanding power‑transmission environments. Constructed from high‑grade mild steel, the coupling undergoes a black‑oxide plating process that not only enhances its aesthetic appeal but also provides a modest level of corrosion resistance, extending service life in humid or oily conditions. The coupling features a 1‑1/8 inch bore that mates perfectly with shafts of the same diameter, while the outer diameter of 2‑1/8 inches ensures a solid, interference‑fit connection. A 3‑1/4 inch overall length gives ample room for the recessed 1/4‑28 x 3/4 inch set screw, which secures the coupling without protruding beyond the outer surface, thereby reducing the risk of accidental snagging or interference with adjacent components.

Key dimensions are carefully balanced to provide both high axial load capacity and torque transmission capability. The design fully engages the shaft without marring, thanks to a smooth internal surface and a set screw that applies even pressure across the mating area. This makes the coupling suitable for both hard and soft shafts, delivering consistent performance across a range of industrial applications, from motor drives to conveyor systems. The product package measures 3.7 x 2.1 x 2 inches and weighs 2.15 pounds, making it easy to handle during installation and maintenance.

Usage

In the field, the CC-112-112-KW excels in environments where reliability and ease of installation are paramount. It is commonly employed in manufacturing plants, material handling equipment, and heavy‑duty machinery that require a secure, non‑slipping connection between motor shafts and driven components. The coupling’s black‑oxide coating helps mitigate the effects of moisture, chemicals, and dust, making it a solid choice for outdoor installations or facilities with high humidity levels.

Installation is straightforward: the shaft is inserted into the bore, the coupling is aligned, and the set screw is tightened to the recommended torque specification. Because the set screw head is recessed, the exterior of the assembly remains smooth, allowing for safe operation around moving parts and reducing the likelihood of accidental contact. The coupling can also be used in retrofit projects where space constraints demand a compact yet robust solution. Its ability to handle both high torque and axial loads makes it suitable for applications such as gearboxes, pump drives, and fan assemblies where precise alignment and load distribution are critical.

FAQ

What shaft sizes are compatible with this coupling?

The coupling is designed for a 1‑1/8 inch (28.6 mm) shaft bore, making it compatible with any shaft of that exact diameter. It can accommodate both hard and soft shaft materials without causing surface damage.

How does the black‑oxide finish affect performance?

The black‑oxide coating provides a modest level of corrosion resistance, helping to protect the steel surface from moisture and mild chemicals. It does not significantly alter the mechanical properties of the steel but does improve visual identification and resistance to surface wear.

Can this coupling be used in high‑speed applications?

Yes, the CC-112-112‑KW is suitable for many high‑speed scenarios, provided that the operating speed does not exceed the limits specified by the manufacturer. Proper alignment and secure set‑screw tightening are essential to maintain balance and prevent vibration.

What is the recommended torque for the set screw?

We recommend tightening the 1/4‑28 x 3/4 inch set screw to the torque value specified in the installation manual, typically between 5 and 7 Nm (Newton‑meters). This ensures a firm grip without over‑compressing the shaft.

Is there a warranty on this product?

Climax Metal Products Company offers a limited one‑year warranty covering material defects and workmanship. For detailed warranty terms, please refer to the product documentation or contact our support team.
