uxcell 10pcs Set Screw Shaft Collars 8mm OD 4mm Width Nickel Steel

Description

Product Overview

The uxcell 10‑piece set screw shaft collars are engineered for precision and durability in demanding mechanical environments. Each collar is forged from high‑grade carbon steel and then nickel‑plated to provide a corrosion‑resistant surface that maintains its appearance and performance even in humid or oily conditions. The collars feature an 8 mm outer diameter, a 4 mm width, and a 3.05 mm bore that matches standard small‑shaft applications, ensuring a snug fit without excessive play.

Designed with a set screw mechanism, these collars allow users to fine‑tune the axial position on a shaft, delivering a firm lock that resists vibration and torque loads. The set screw is tightened with a standard hex wrench, eliminating the need for specialized tools or complex assembly steps. This simplicity speeds up installation and reduces downtime during maintenance or equipment upgrades.

Beyond the basic dimensions, the collars are built to withstand mechanical stress. The nickel‑plated carbon steel construction offers a tensile strength that exceeds typical clamp‑on solutions, making the collars suitable for high‑load applications such as gear positioning, pulley alignment, and bearing support. The material choice also contributes to a longer service life, as the protective nickel layer mitigates wear and surface fatigue.

Each package contains ten identical collars, providing a cost‑effective solution for batch projects or for stocking spare parts in a workshop. The consistent quality across the set ensures that every unit performs identically, which is critical for applications that require uniform spacing or repeatable positioning across multiple shafts.

Usage

These shaft collars are widely adopted in automotive repair and performance tuning, where precise alignment of shafts, gears, and pulleys is essential for smooth power transmission. Technicians use the collars to set the exact location of a drive shaft before installing belts or chains, preventing slippage and reducing wear on downstream components.

In robotics, the collars serve as reliable positioners for motor shafts, sensor mounts, and actuator linkages. The adjustable set screw enables fine adjustments during prototype development, allowing engineers to experiment with different gear ratios or sensor placements without redesigning the entire assembly.

RC aircraft enthusiasts also benefit from the lightweight yet sturdy design. The collars can secure propeller shafts, control surface linkages, and motor mounts, ensuring that aerodynamic forces do not shift components during flight. Their compact size and easy installation make them a favorite for hobbyists who need quick, repeatable setups.

Beyond these specific sectors, the collars are suitable for any machinery that requires a reliable stop, spacer, or bearing surface. They can be employed in conveyor systems, small‑scale manufacturing equipment, and even DIY projects where a dependable mechanical lock is needed.

Why Choose Us

Choosing uxcell means selecting a brand with a reputation for quality control and customer support. Every collar undergoes rigorous testing for dimensional accuracy, hardness, and corrosion resistance before it leaves the factory. This commitment to consistency reduces the risk of mismatched parts that could compromise system performance.

FAQ

What shaft sizes are compatible with these collars?

The collars have a 3.05 mm bore, which fits shafts ranging from 3 mm to 3.1 mm in diameter. This tolerance allows for a secure fit on most standard small‑shaft components used in hobbyist and industrial projects.

Can the set screw be tightened with a standard hex key?

Yes, the set screw uses a standard 2.5 mm hex socket, so a common hex wrench or Allen key can be used to secure the collar without the need for specialized equipment.

Are the collars suitable for high‑temperature environments?

The nickel‑plated carbon steel can operate safely up to approximately 200 °C (392 °F). For applications that exceed this temperature, a heat‑treated alloy may be required.

How many collars are included in one package?

Each box contains ten identical shaft collars, providing a convenient bulk quantity for multiple installations or spare parts inventory.

What warranty does uxcell offer on these collars?

uxcell provides a one‑year limited warranty covering manufacturing defects. If a collar fails due to material or workmanship issues within this period, a replacement will be issued after verification.
