uxcell Double Split Shaft Collar Set 6pcs 4mm Bore Aluminum Alloy

Description

Product Overview

The uxcell double split shaft collar set is crafted from high‑grade 6061 aluminum alloy, delivering a perfect balance of strength and lightness. Each collar features a 4 mm bore, an 18 mm outer diameter, and an 8 mm thickness, dimensions that make them suitable for a wide range of shaft sizes while maintaining a compact profile. The split‑design allows the collar to be opened, placed around a shaft, and then securely tightened with set screws, ensuring a firm grip without the need for disassembly of the entire assembly. This design not only speeds up installation but also provides precise positioning, reducing the risk of slippage during operation.

Beyond the mechanical advantages, the aluminum construction offers excellent corrosion resistance, extending the service life even in harsh environments such as automotive workshops, robotic cells, and manufacturing floors. The set includes six individual collars, each finished with a smooth, machined surface that minimizes wear on the shaft and reduces noise during operation. Whether you need to secure gears, pulleys, sprockets, or other rotating components, these collars deliver consistent performance and reliability.

Usage

These split shaft collars are ideal for applications where quick installation and reliable holding power are essential. In automotive repair shops, technicians use them to secure transmission shafts, ensuring that components stay aligned during testing and maintenance. In robotic systems, the collars serve as precise stops for linear actuators, providing repeatable positioning that is critical for high‑precision tasks such as pick‑and‑place operations or CNC machining.

Industrial machinery benefits from the collars’ ability to act as mechanical limits for rotating shafts, preventing over‑travel and protecting downstream equipment from damage. Their lightweight nature also makes them suitable for applications where added mass could affect system dynamics, such as in high‑speed motor assemblies or aerospace components. The easy‑to‑use split design means that adjustments can be made on‑the‑fly, allowing engineers to fine‑tune clearances without extensive downtime.

FAQ

What shaft sizes are compatible with these collars?

The collars are designed for shafts with a 4 mm bore, but the split mechanism allows them to accommodate a range of shaft diameters up to approximately 6 mm, depending on the tightness of the set screws.

Can the collars be used in high‑temperature applications?

Yes, the 6061 aluminum alloy maintains its mechanical properties up to about 150 °C (302 °F). For temperatures beyond this range, a different material such as stainless steel may be more appropriate.

How do I install the collars correctly?

Open the split by loosening the set screws, place the collar around the shaft at the desired position, then tighten the screws evenly until the collar is firmly clamped. Ensure the shaft is clean and free of debris for optimal grip.

Are replacement set screws included?

Each collar comes with its own set of high‑strength steel screws. If you need additional screws, they can be ordered separately from uxcell’s spare parts catalog.

What warranty does uxcell provide?

All uxcell shaft collars are covered by a one‑year limited warranty against material defects and workmanship issues, reflecting our confidence in product quality and durability.
