uxcell 10pcs Set Screw Collars 4mm Stainless Steel 9mm OD 7mm Width

Description

Product Overview

The uxcell 10‑piece set screw collars are engineered to deliver precise shaft positioning and reliable locking in a compact, easy‑to‑install package. Each collar features a 4 mm bore that matches standard shaft sizes, a 9 mm outer diameter for a solid bearing surface, and a 7 mm width that provides ample material strength while remaining lightweight. Constructed from high‑grade 304 stainless steel, the collars offer excellent corrosion resistance, high tensile strength, and long‑term durability even in harsh industrial environments. The set screw design allows users to fine‑tune the collar position along the shaft, ensuring exact alignment for gears, pulleys, and other rotating components. With a total of ten collars per pack, users have the flexibility to outfit multiple machines or keep spares on hand for future maintenance. The collars are compatible with standard hex wrenches, eliminating the need for specialized tools and reducing installation time.

Usage

These versatile collars are suited for a wide range of applications across automotive, robotics, aerospace, and hobbyist RC projects. In automotive assemblies, they serve as precise stops for camshafts, crankshafts, and transmission components, helping to maintain timing accuracy and reduce wear. Robotics engineers rely on the adjustable set screw mechanism to secure sensor housings, motor shafts, and actuator linkages, where exact positioning is critical for repeatable motion control. In the aerospace sector, the stainless‑steel construction meets stringent material standards, making the collars appropriate for lightweight yet strong fastening solutions on aircraft control surfaces and UAV frames. Hobbyists building RC airplanes or drones benefit from the easy installation and reliable locking, ensuring that propeller shafts and motor mounts stay firmly in place during high‑speed flight. The collars also function effectively as spacers or bearing surfaces in conveyor systems, pump assemblies, and industrial machinery where vibration damping and alignment are essential.

FAQ

What shaft sizes are compatible with these collars?

The collars are designed for a 4 mm bore, making them compatible with any shaft that has a 4 mm diameter. This standard size is common in many small‑scale mechanical and hobbyist applications, allowing the collars to be used on a wide variety of equipment without the need for additional machining.

How do I install the set screw securely?

Installation is straightforward: slide the collar onto the shaft at the desired location, align the set screw hole with the shaft, and tighten the screw using a standard hex wrench. The set screw creates a firm lock that prevents the collar from moving under load, and the process can be completed without disassembling surrounding components.

Are these collars suitable for high‑temperature environments?

Yes. The 304 stainless steel material maintains its mechanical strength and corrosion resistance at elevated temperatures typically encountered in industrial machinery, automotive engines, and aerospace systems. However, for extreme temperature applications exceeding the material’s rated limits, a specialized alloy may be recommended.

Can the collars be used as spacers?

Absolutely. Their solid construction and precise dimensions make them ideal for spacing applications, such as separating gears, pulleys, or bearing housings to achieve the correct axial distance. The adjustable set screw allows you to lock the spacer in place securely.

What warranty does uxcell provide for these collars?

uxcell offers a one‑year limited warranty covering material defects and workmanship. If a collar fails due to manufacturing issues within the warranty period, we will replace the item or provide a refund, subject to proof of purchase and return conditions.
