Introducing our high-quality Single Split and Double Split Screw Collars, featuring a sleek black finish, designed for diverse power transmission applications. As essential machine components, these collars serve multiple purposes, including acting as mechanical stops, locating components accurately, and providing reliable bearing faces. Sourced from trusted China suppliers and manufactured in our state-of-the-art factory, our screw collars ensure durability and performance for your projects. Optimize your mechanical systems with our expertly crafted collars today!

    The collar is a critical mechanical component whose simple yet important design plays an important role in power transmission applications such as motors and gearboxes. The collar serves as a mechanical stop, positioning component and support surface, and its simple design makes it easy to install.

    We can manufacture all sizes of shaft collars as per your request. A double split ring, also known as a two-piece split ring, is a mechanical component used to secure and position components on a shaft. It is designed with two independent halves that can be installed and removed from the shaft without sliding along the entire length of the shaft. This design allows for easy installation and removal without the need to remove other components on the shaft.

    ⚙️ Mechanical Function

    Double split rings are typically held in place using screws or a clamping mechanism to provide a secure grip on the shaft and prevent slipping. This type of collar is often used in applications that require frequent adjustments or replacement of components.

    🏭 Industrial Application

    Commonly used in machinery, conveyor systems, and power transmission equipment. Available in steel, stainless steel, and aluminum to suit specific application requirements.

    • Material test reports and Quality Inspection Reports provided upon request.
    • Detailed packing videos and photos available.
    • Drawing formats: PDF, CAD/DWG/DXF, IGS/STP. Professional customization service available.

    Threaded shaft collars offer the same qualities and benefits as sliding bore collars while offering additional functionality. Threaded collars provide better axial retention than smooth bore collars while being easier to install and adjust than solid ring locking devices.

    • Excellent fit, finish and hold.
    • Strictly control the perpendicularity between the surface and the hole.
    • The bore size is printed on each collar.
    • Black oxide treatment creates retention and resists corrosion.
    • Available in black oxidized/galvanized steel, stainless steel, and aluminum.
    Frequently Asked Questions
    Q1: What is the main advantage of a double split (two-piece) shaft collar?
    A: The two-piece design allows for installation and removal anywhere on the shaft without needing to disassemble other components, saving significant time during maintenance or adjustments.
    Q2: What materials are available for your shaft collars?
    A: We offer a variety of materials including Carbon Steel (with black oxide or galvanized finish), Stainless Steel (SUS 303/304/316), and Aluminum to suit different environment requirements.
    Q3: Do you provide custom size manufacturing?
    A: Yes, while our standard sizes range from 1/8" to 6" (and 3mm to 150mm), we can manufacture non-standard sizes based on your specific professional drawings or requirements.
    Q4: How do you ensure the quality of the collars?
    A: We strictly control the perpendicularity between the surface and the bore. We also provide Material Test Reports and Quality Inspection Reports upon request to ensure all components meet specifications.
    Q5: What is the lead time for bulk orders?
    A: For bulk goods that are in stock, the delivery time is approximately 60 days. For custom bulk orders, it is also around 60 working days following the sample approval process.
    Q6: Can I get a sample before placing a large order?
    A: Yes, we provide free samples after an order is confirmed. Please note that the international transportation costs for these samples are to be covered by the customer.
