KuaKee Aluminum Alloy 4-Pack Clamp-On Shaft Collar 8mm Bore 14mm OD

Description

Product Overview

The KuaKee 4‑Pack aluminum alloy clamp‑on shaft collars are engineered to meet the rigorous demands of modern manufacturing environments. Each collar features an exact 8mm bore, a 14mm outer diameter, and an 8mm width, providing a secure fit for a wide range of shaft sizes commonly found in CNC machine tools, conveyor systems, and other industrial equipment. The collars are fabricated from high‑grade aluminum alloy that has undergone a surface oxidation treatment, delivering superior corrosion resistance, rust prevention, and a lightweight profile that reduces overall system inertia. The design incorporates a screw‑style clamping mechanism that utilizes high‑strength bolts to lock the collar firmly in place without damaging the shaft surface, ensuring repeatable positioning and reliable torque transmission. Detailed specifications include a package dimension of 1.1 x 1.1 x 0.31 inches, a net weight of 0.81 ounces per unit, and compliance with industry standards for clamp‑on shaft collars. The product model number KK‑SCCAW‑001 reflects KuaKee’s commitment to quality and precision engineering, and the item has earned a strong customer rating of 4.6 out of 5 stars based on 37 reviews, underscoring its performance and durability in real‑world applications.

Usage

These clamp‑on shaft collars are versatile components that excel in a variety of usage scenarios. In CNC machining centers, they serve as reliable stoppers and positioning devices for tool holders, ensuring precise alignment of cutting tools and reducing vibration during high‑speed operations. In conveyor belt systems, the collars act as secure anchors for timing pulleys, sprockets, and gear assemblies, facilitating smooth power transmission and preventing slippage under heavy loads. The lightweight aluminum construction makes them especially suitable for applications where minimizing rotational mass is critical, such as in high‑speed rotary tables and robotic arms. Installation is straightforward: the collar slides onto the shaft, the bolt holes are aligned, and the high‑strength bolts are tightened to the recommended torque, providing a repeatable and secure fit that can be easily disassembled for maintenance or reconfiguration. Their corrosion‑resistant finish ensures long‑term performance even in harsh environments, including exposure to moisture, chemicals, and temperature fluctuations commonly encountered in manufacturing plants, automotive workshops, and material handling facilities.

Why Choose Us

Choosing KuaKee means selecting a partner that prioritizes engineering excellence, material quality, and customer satisfaction. Our aluminum alloy shaft collars are produced using precision casting and machining processes that guarantee tight tolerances and consistent bore dimensions across every unit, eliminating the variability that can lead to misalignment or premature wear. The surface oxidation treatment not only enhances corrosion resistance but also provides a smooth finish that reduces friction against the shaft, extending the service life of both the collar and the shaft itself. Each collar is rigorously inspected for dimensional accuracy, bolt thread integrity, and overall finish quality before it leaves our facility, ensuring that you receive a product that meets or exceeds industry expectations. In addition to the robust physical attributes, KuaKee offers responsive technical support and a clear warranty policy, giving you confidence that any questions or concerns will be addressed promptly.

FAQ

What shaft sizes are compatible with these collars?

The collars are designed for an 8mm bore, but the package includes a variety of sizes ranging from 6mm to 35mm bore, allowing you to select the exact fit for your specific shaft dimensions.

Can the collars be reused after removal?

Yes, the screw‑style clamping mechanism is engineered for repeated installation and removal without compromising the integrity of the collar or the shaft, making them ideal for applications that require frequent adjustments.

How do I ensure proper torque when installing the bolts?

We recommend using a calibrated torque wrench and tightening the bolts to the manufacturer‑specified torque value, typically between 5‑7 Nm, to achieve a secure fit without over‑tightening.

Are these collars suitable for high‑temperature environments?

The aluminum alloy material maintains its strength and dimensional stability up to approximately 150°C (302°F), making it suitable for many industrial temperature ranges, though extreme heat applications may require alternative materials.

What warranty does KuaKee provide?

KuaKee offers a one‑year limited warranty covering material defects and workmanship, backed by responsive technical support to assist with any installation or performance questions.
