Shaft Collar 2-1/4 in Split Stainless Steel Clamp Set - Durable Fit

In this review the AZSSMUK two-piece split shaft collar is examined for workshop and industrial use where a secure, corrosion-resistant stop or spacer is needed. The bottom line: this set delivers reliable holding power and straightforward installation thanks to its two-piece design and 304 stainless steel construction, making it especially useful for machinery, motor bases, and drive shafts where access to shaft ends is limited. For anyone needing a reusable, robust collar that resists rust, this review finds the collar to be a practical choice.

Key Features

• Two-piece split design: Allows installation and removal anywhere along the shaft without disassembling adjacent components, saving time on maintenance and retrofits.
• 304 stainless steel construction: Provides better corrosion resistance and weldability than regular steel, extending service life in damp or outdoor environments.
• Bore diameter 2-1/4 in: Fits shafts of that size precisely and is suitable for standard industrial and hobby shafts that match the diameter.
• Solid holding method: Uses a socket cup-point setscrew that improves holding power on softer shaft materials for secure axial positioning.
• Compact footprint: With a 3-1/4 in outside diameter and 3/4 in width, it offers good radial and axial support while keeping the collar size moderate.
• Pack of two: Ships with two matching collars and screws so spares or paired installations are convenient.

Who It's For

The AZSSMUK split collar is aimed at technicians, machine builders, and hobbyists who need a durable, removable shaft stop or spacer without pulling their shaft out of a gearbox or motor. It suits applications in gearbox assemblies, motor bases, drive shafts, agricultural implements, and many workshop fixtures where corrosion resistance and a clean fit matter.

Those who should look elsewhere include users who require a clamp-style or keyway-mounted collar for very high torque locking, or installations needing custom machining beyond the standard 2-1/4 in bore; this product is a setscrew-style split collar optimized for axial stops and moderate holding loads.

Pros & Cons

Pros

• Durable 304 stainless construction gives good corrosion resistance for outdoor and marine-adjacent use.
• Two-piece split design makes installation quick and allows placement anywhere along the shaft.
• Socket cup-point setscrew offers improved holding on softer shafts and simple positioning.
• Pack includes two collars and screws so users get a matched pair for assemblies.

Cons

• Setscrew-style fastening is best for axial stops and moderate loads and may not be ideal where extremely high torque locking is necessary.
• Only available for the specified 2-1/4 in bore size, so different shaft diameters require other items.

Specifications

Our Verdict

The AZSSMUK 2-1/4 in split stainless shaft collar is a practical, good-value choice for anyone needing a corrosion-resistant, easy-to-install axial stop or spacer. It excels where removability, fit, and rust resistance matter, making it well suited to industrial equipment, motor bases, and hobby craft projects that match the bore size.

Frequently Asked Questions

Can this collar be fitted without removing other components?
Yes. The two-piece split design allows disassembly and reassembly anywhere along the shaft without removing adjoining parts.

Is the material suitable for outdoor use?
Yes. Constructed from 304 stainless steel, it offers better corrosion resistance than regular steel for damp or outdoor environments.

Will the setscrew hold on softer shafts?
The socket cup-point setscrew improves holding power on softer shaft materials for secure axial positioning, suitable for moderate loads.
