MECCANIXITY Shaft Collar 2 Inch Bore Carbon Steel – 2 Pcs

The MECCANIXITY carbon steel shaft collar is designed to secure one end of a ball guide shaft while functioning as a reliable stop to prevent slip-out. Ideal for motor bases, drive shafts, and machine tools, this collar proves versatile in industrial automation and conveyor belt systems. The package includes two collars with M10 screws, offering stable performance, oxidation resistance, and a durable locking surface. Its compact size (50 mm ID) ensures a snug fit on standard 2 inch shafts commonly used in small to mid-size conveyors.
Key features include a robust carbon steel construction, corrosion resistance, and a tight clamp that closely matches the guide shaft. The collars deliver strong locking force and support, helping maintain alignment in dynamic conveyor environments. They’re suitable for daily upgrades on lawn or garden equipment as well, offering cross-application value in maintenance operations.
MECCANIXITY Shaft Collar 2 Inch Bore Zinc Plated – Silver

This zinc plated shaft collar offers corrosion resistance with the same 2 inch bore size and 5/8 inch thick collar design. The packaging provides a single collar with two M10 screws, making it well-suited for applications requiring a quick, simple fit on guide shafts. The zinc finish adds a protective layer that can extend service life in environments where moisture or humidity is a concern, such as outdoor conveyors or wash-down areas.
Designed to closely fit the guide shaft, the collar presents a strong locking mechanism and reliable support. It pairs well with standard 2 inch conveyor components to maintain precise shaft positioning and reduce unwanted movement during operation. Users can leverage its straightforward installation for maintenance routines or initial system assembly.
MECCANIXITY Shaft Collar 2 Inch Bore Single Split Aluminum

The aluminum, single-split shaft collar provides a lightweight alternative with a 2 inch bore and a robust locking mechanism. With dimensions of 50 x 85 x 22 mm, this collar is tailored for quick adjustments and easier installation on tighter conveyor assemblies. The aluminum construction reduces overall system weight while maintaining resistance to wear and impact, a valuable trait for conveyors that require frequent reconfiguration or repairs.
Its split design simplifies mounting and removal, enabling rapid maintenance without disassembling upstream components. The collar’s tight fit ensures close engagement with the guide shaft, offering dependable stability and support in normal to moderate-load conveyor operations. The product suits applications where weight savings and corrosion resistance are desired without sacrificing locking strength.
NTN UCFX10-200D1 Medium Duty Flange Bearing

The NTN UCFX10-200D1 is a medium-duty flange bearing designed for robust performance in conveyor systems. It features a cast iron housing that provides vibration damping and structural rigidity, with a wide inner ring to handle moderate to high radial loads and some thrust. The unit is regreasable, and integrates synthetic rubber lip seals to retain lubricant while keeping contaminants out. Flinger seals enhance protection, extending service life in challenging industrial environments.
With a 2 inch bore, this flange bearing aligns well with standard screw conveyor shafts, ensuring smooth rotation and dependable support for rotating elements. It suits applications requiring reliable load handling, moderate speeds, and easy maintenance through regular lubrication. This bearing unit is a solid choice for upgrade projects or new builds that demand durability in tight spacer configurations.
Browning VF4S-232 Normal-Duty Flange Unit

The Browning VF4S-232 is a normal-duty flange unit designed for reliable performance in conveyor assemblies requiring strong sealing and rigidity. The cast iron housing provides damping and rigidity, while the double-sealed ball bearing insert protects against contaminants and retains lubrication. The flange unit is configured for 2 inch bore applications with 5-1/8 inch bolt hole spacing, offering solid stability for moderate radial loads and thrust or mixed-loading scenarios common in screw conveyors and material handling lines.
Flinger seals contribute extra protection, guarding against lubricant loss and external intrusion. This makes the Browning unit suitable for longer service intervals in busy manufacturing environments. Its robust build supports stable operation across a range of ambient temperatures and mounting orientations, helping maintain conveyor efficiency and reducing downtime linked to bearing failures.
Buying Guide: Key Purchase Considerations
When selecting components for a 2 inch screw conveyor system, consider these factors to ensure compatibility, reliability, and cost-efficiency:
- Shaf t fit and bore size: Confirm the shaft diameter and bore tolerance to ensure a snug, secure connection with collars or bearings. In 2 inch systems, precise ID (inner diameter) matters for proper clamping and alignment.
- Material and environment: Carbon steel collars offer strength, while zinc plating and aluminum provide corrosion resistance and weight savings. Choose based on exposure to moisture, chemicals, and outdoor conditions.
- Locking mechanism: Set-screw designs are common, but split collars or clamping collars can offer easier installation and higher locking force in dynamic systems. Consider maintenance access needs.
- Bearing type and seals: Flange bearings with seals and flingers deliver better lubricant retention and contaminant protection, crucial for dust-heavy conveyor environments.
- Mounting style: Flange units simplify mounting to stationary frames and provide robust support for axial loads. Match bolt hole spacing to your conveyor frame for straightforward installation.
- Maintenance and replacement: Interchangeability with readily available standard parts reduces downtime. Look for regreasable bearings and service-friendly designs.
- Cost vs. durability: While premium components may cost more upfront, they often yield lower total cost of ownership through longer service life and reduced maintenance.
In sum, the right combination of collars and bearings for a 2 inch screw conveyor improves shaft stability, minimizes slip, reduces wear, and extends overall system life. The five products highlighted provide a spectrum of options—from carbon steel and zinc plated collars to aluminum variants and robust flange bearings—so you can tailor your setup to the specific demands of your application, whether it’s a compact shop setup or a larger manufacturing line.
