Description
Product Overview
The Climax Metal 2C-125 clamp‑on shaft collar is engineered for demanding industrial environments where reliability and precision are paramount. Constructed from high‑grade steel, the collar receives a black oxide plating that not only enhances visual appeal but also adds a layer of corrosion resistance, extending service life even in humid or chemically aggressive settings. The two‑piece design incorporates a robust outer ring and an inner sleeve that together create a 360‑degree clamping force, ensuring the shaft remains securely locked without any slippage under load.
With a bore size of 1‑1/4 inches and an outer diameter of 2‑1/16 inches, this collar fits a wide range of standard shafts used in pumps, gearboxes, conveyors, and other power transmission equipment. The included 1/4‑28 x 3/4″ set screw provides a simple yet effective method for tightening the assembly, eliminating the need for extensive disassembly or specialized tools. The product dimensions of 4 x 2.8 x 0.4 inches and a lightweight of 6.72 ounces make it easy to handle during installation and maintenance procedures.
Designed to be effective on both hard and soft shafts, the collar’s geometry fully engages the shaft surface without causing marring or deformation. This feature is especially valuable when working with delicate or precision‑machined components where surface integrity must be preserved. The black oxide finish also contributes to a reduced coefficient of friction, facilitating smoother operation and minimizing wear over time.
Usage
In industrial applications, the 2C-125 collar is commonly employed in machinery that requires a secure, non‑intrusive method of shaft coupling. Whether used in hydraulic systems, motor assemblies, or conveyor drives, the collar provides a reliable means of transmitting torque while allowing for easy removal and re‑installation during routine maintenance. Its ability to clamp firmly without the need for major disassembly makes it an ideal choice for retrofit projects where downtime must be minimized.
The collar’s versatility extends to both hard and soft shaft materials, including stainless steel, carbon steel, aluminum, and even certain polymer composites. This adaptability ensures that engineers and technicians can rely on a single part to address multiple shaft types across a plant’s equipment inventory, simplifying spare‑part management and reducing inventory costs.
When installed, the collar delivers consistent clamping force that resists vibration‑induced loosening, a common challenge in high‑speed or high‑torque applications. The set screw’s fine thread (1/4‑28) allows for precise torque adjustments, enabling users to achieve the exact clamping pressure required for their specific operational parameters. This precision contributes to longer equipment life and lower maintenance intervals.

FAQ
What shaft materials can the 2C-125 collar be used with?
The collar is designed to work with a variety of shaft materials, including stainless steel, carbon steel, aluminum, and certain polymer composites. Its non‑marring design ensures that the shaft surface remains intact regardless of material hardness.
How do I determine the correct torque for the set screw?
We recommend consulting the equipment manufacturer’s specifications for the required clamping force. In general, a torque setting that achieves a firm but not over‑tightened condition will provide optimal performance. Our technical support team can assist with precise torque values based on your application.
Is the black oxide coating sufficient for outdoor or marine environments?
While the black oxide coating offers basic corrosion resistance, for highly corrosive environments such as marine applications, additional protective measures like a silicone sealant or a secondary coating may be advisable to extend service life.
Can the collar be reused after removal?
Yes, the 2C-125 collar can be removed and reinstalled multiple times without loss of performance, provided the set screw is not over‑tightened and the black oxide surface remains intact. Regular inspection for wear or damage is recommended.
What is the warranty coverage for this product?
Climax Metal Products offers a one‑year limited warranty covering material defects and workmanship. This warranty does not cover damage caused by improper installation, misuse, or external factors such as corrosion beyond the protective coating.
