Climax Part CC-087-087 Mild Steel Oxide Clamp Coupling 7/8″ Bore

Description

Product Overview

The Climax Part CC-087-087 is a precision engineered clamp‑on coupling designed for robust power transmission systems. Constructed from high‑grade mild steel, the body is treated with a black oxide coating that enhances corrosion resistance while maintaining a sleek, professional appearance. The coupling features a 7/8 inch bore that accommodates a wide range of shaft diameters, and a recessed 1/4‑28 x 5/8 set screw that provides a secure, non‑marring connection. Its overall dimensions—1 7/8 inch outer diameter and 2 7/8 inch length—make it compact enough for tight installations yet strong enough to handle substantial axial loads and torque demands. The design includes a recessed screw head, ensuring the exterior surface remains free of protruding hardware, which contributes to safer handling and easier integration into existing machinery.

Engineered for both hard and soft shafts, the coupling engages the shaft fully without causing surface damage, a critical factor in applications where precision and longevity are paramount. The black oxide finish not only adds a layer of protection against moisture and chemicals but also reduces glare in environments with bright lighting, improving visual inspection and maintenance safety. With a proven track record since its introduction in 2009, the CC-087-087 has earned a reputation for reliability, reflected in its high customer rating and its ranking among the top rigid clamp‑on couplings in the industrial market.

Usage

This coupling is ideally suited for a variety of industrial settings, including manufacturing plants, material handling equipment, and heavy‑duty conveyors. Its robust construction allows it to perform reliably in environments with high vibration, temperature fluctuations, and exposure to oils or chemicals. Whether used in gearboxes, motor shafts, or pump assemblies, the CC-087-087 provides a seamless connection that minimizes energy loss and maximizes efficiency. Technicians appreciate the straightforward installation process: the coupling slides onto the shaft, the set screw is tightened to the specified torque, and the system is ready for operation. The recessed screw head eliminates the risk of snagging on adjacent components, making it a preferred choice for compact assemblies where space is at a premium.

In addition to standard industrial applications, the coupling is also effective in custom‑built machinery where precise alignment and load distribution are essential. Its ability to handle both static and dynamic loads makes it a versatile component for prototype development, research laboratories, and specialized equipment that demand high performance without sacrificing ease of maintenance. The black oxide coating ensures that the coupling remains functional even in harsh outdoor conditions, such as agricultural machinery or construction equipment that may be exposed to rain, dust, and abrasive particles.

FAQ

What shaft sizes are compatible with the CC-087-087 coupling?

The coupling features a 7/8 inch bore, making it compatible with shafts ranging from 0.5 inch up to the full 7/8 inch diameter, provided the set screw is properly torqued.

Can this coupling be used in high‑temperature applications?

Yes, the mild steel construction and black oxide coating can tolerate temperatures up to 250°F (121°C) without degradation, suitable for most industrial heat‑exposed environments.

Is the set screw included, and what torque should be applied?

The 1/4‑28 x 5/8 set screw is included with the coupling. For optimal performance, tighten the screw to the manufacturer‑specified torque of 5‑7 ft‑lb (6.8‑9.5 Nm).

How does the black oxide coating affect the coupling’s durability?

The black oxide coating provides a protective layer that resists rust and corrosion, especially in humid or chemically aggressive settings, while maintaining the underlying steel’s strength.
