Description
Product Overview
The uxcell 10‑piece set screw collar collection is engineered to deliver precise shaft positioning for a wide range of mechanical applications. Each collar features a 3 mm bore that accommodates standard shafts, an 8 mm outer diameter for robust engagement, and a 7 mm thickness that provides ample material strength while remaining compact enough for tight spaces. Crafted from high‑grade 304 stainless steel, the collars resist corrosion, maintain dimensional stability under temperature fluctuations, and endure the repetitive stresses typical of industrial environments.
Design simplicity meets functional versatility in these clamp‑on collars. The integrated set screw, accessed with a standard hex wrench, allows users to fine‑tune the collar’s axial position along the shaft, ensuring exact alignment of gears, pulleys, or bearings. Once tightened, the screw creates a secure lock that prevents slippage, even under high torque conditions. This adjustable feature eliminates the need for permanent fastening methods, offering flexibility for prototyping, maintenance, or equipment upgrades.
Beyond the core mechanical benefits, the collars are lightweight, weighing only 0.63 ounces per set, which minimizes added inertia on rotating assemblies. Their compact package dimensions of 3.43 × 2.05 × 0.71 inches facilitate easy storage and bulk shipping, making them an economical choice for manufacturers, hobbyists, and repair shops alike. The product’s best‑seller rank in the Clamp‑On Shaft Collars category underscores its popularity among professionals seeking reliable, cost‑effective shaft management solutions.
Installation is straightforward: slide the collar onto the shaft at the desired location, align the set screw hole with the shaft’s flat or groove, and tighten the screw using a compatible hex key. No additional tools, disassembly, or welding are required, reducing downtime and labor costs. The design also allows for quick removal and repositioning, supporting iterative design processes and on‑the‑fly adjustments during testing phases.
Usage
These collars excel in automotive applications where precise gear spacing and secure wheel hub positioning are critical. Whether used to lock a driveshaft, serve as a stop for a steering column, or act as a spacer in a transmission assembly, the set screw mechanism ensures consistent performance under dynamic loads. The stainless‑steel construction also protects against road‑salt corrosion, extending service life in harsh environments.
In robotics and RC aircraft, the collars provide a dependable method for aligning motor shafts, securing sensor mounts, and defining travel limits for actuators. Their low profile and high strength make them suitable for lightweight drone frames, hobbyist robot arms, and custom‑built RC planes where weight savings and reliability are paramount. The ability to adjust position without permanent alteration enables rapid prototyping and fine‑tuning of control surfaces or propulsion systems.

FAQ
What size shafts are compatible with these collars?
The collars are designed for shafts with a 3 mm diameter bore. They fit standard metric shafts and can be used on both solid and hollow shafts as long as the outer diameter matches the 3 mm specification.
Can the set screw be tightened with a standard hex wrench?
Yes, the set screw uses a common hex socket size that works with most standard hex wrenches or Allen keys. No special tools are required, making installation quick and convenient.
Are these collars suitable for high‑temperature environments?
While stainless steel tolerates a wide temperature range, the set screw material may have limits. For extreme heat applications, verify the specific temperature rating of the screw material or consider using a heat‑treated variant.
How many collars are included in the package?
The package contains ten individual set screw collars, providing ample quantity for multiple shafts or for keeping spares on hand for future maintenance.
Do you offer bulk pricing for larger orders?
Yes, uxcell provides volume discounts for bulk purchases. Contact our sales team with your required quantity, and we will provide a tailored quote that reflects the savings for larger orders.
