Threaded shaft collars are precision mechanical components designed to secure parts onto shafts, rods, or axles in various industrial and mechanical applications. Unlike standard shaft collars, threaded shaft collars feature internal or external threads that allow for fine adjustment, locking, or positioning with added stability. They are commonly used in machinery, automation systems, conveyor belts, and motion control setups where precise alignment and secure fastening are critical. Made from materials like stainless steel, aluminum, or plastic, these collars offer durability and resistance to corrosion, making them ideal for harsh environments. Their threaded design enables easy installation and removal without requiring additional tools in many cases, streamlining maintenance and adjustments in equipment.
Below is a detailed table outlining the standard parameters for our threaded shaft collars. These specifications ensure compatibility and optimal performance across various uses.
| Parameter | Description | Standard Range |
|---|---|---|
| Inner Diameter (ID) | The diameter of the shaft that the collar fits onto. | 1/4 inch to 4 inches (6 mm to 100 mm) |
| Outer Diameter (OD) | The external diameter of the collar itself. | 1/2 inch to 6 inches (12 mm to 150 mm) |
| Thread Type | The specification of threads, such as metric or imperial. | M6 to M48, or 1/4-20 to 2-1/2 UNC/UNF |
| Material | Primary materials used in construction. | Stainless Steel (SS304, SS316), Aluminum (6061-T6), Plastic (Nylon, Acetal) |
| Thread Direction | Orientation of threads (internal or external). | Internal Threads, External Threads, or Combination |
| Load Capacity | Maximum axial or radial load the collar can withstand. | Up to 5000 N (axial), varies by material and size |
| Temperature Range | Operating temperature limits based on material. | -40°C to 200°C for steel, -20°C to 80°C for plastic |
| Finish/Coating | Surface treatments for enhanced performance. | Zinc Plated, Anodized, Black Oxide, or Plain |
Threaded shaft collars are utilized in numerous industries due to their adaptability and reliability. Common applications include:
What is the primary difference between threaded and set screw shaft collars?
Threaded shaft collars use threads for adjustment and locking, offering finer control and often tool-less operation, whereas set screw collars rely on screws driven into the shaft, which can mar the surface and require tools for adjustments.
How do I choose the right material for a threaded shaft collar?
Select based on your application: stainless steel for high strength and corrosion resistance in harsh environments, aluminum for lightweight and moderate corrosion resistance, and plastic for electrical insulation, non-magnetic properties, or where low friction is needed.
Can threaded shaft collars be used on rotating shafts?
Yes, they are designed for both static and rotating applications. Ensure the collar is properly tightened and the material matches the speed and load conditions to prevent loosening or wear.
What thread types are available for these collars?
We offer a range of thread types including metric (e.g., M6, M8) and imperial (e.g., 1/4-20, 3/8-16), with options for coarse or fine threads to suit specific torque and adjustment requirements.
How do I install a threaded shaft collar correctly?
Slide the collar onto the shaft to the desired position. For internally threaded types, rotate the collar to engage the threads with the shaft or a mating component. For externally threaded versions, use a nut or threaded receiver. Tighten securely but avoid over-torquing to prevent damage.
Are custom sizes and threads available?
Absolutely, we provide customization for inner diameters, outer diameters, thread specifications, and special coatings. Contact our support team with your requirements for tailored solutions.
What maintenance is required for threaded shaft collars?
Minimal maintenance is needed. Periodically check for loosening due to vibration and ensure threads are clean and free of debris. In corrosive environments, inspect for wear and re-tighten as necessary.
Can these collars be used in high-temperature applications?
Yes, but material selection is crucial. Stainless steel collars can handle up to 200°C, while plastic variants are limited to lower temperatures (around 80°C). Always verify the temperature ratings before use.
Do threaded shaft collars come with locking mechanisms?
Many models include built-in locking features such as nylon inserts or prevailing torque threads to prevent unintentional loosening under vibration, enhancing reliability in dynamic systems.
Where can I purchase threaded shaft collars?
They are available through our online store, authorized distributors, and industrial suppliers. Check our website for detailed catalogs, pricing, and shipping options to find the right product for your needs.
