Introducing our high-quality Single Split and Double Split Screw Collars, designed with a sleek black finish. These essential machine components are widely used in various power transmission applications. Our collars serve multiple purposes, acting as mechanical stops, locating components, and bearing faces. As a leading manufacturer in China, we are committed to providing durable and reliable solutions for your engineering needs. Partner with trusted suppliers and our factory to enhance your projects with our exceptional screw collars

    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.

    Size Range

    1/8" to 6" and 3mm to 150mm. Custom non-standard sizes available.

    Materials

    Carbon steel, SUS 303/304/316, Aluminum, and more.

    Available Types

    One-piece, Two-piece, Threaded, Shaft coupling, Heavy-duty, Mountable, Quick Clamping, Set screw, etc.

    Packaging

    Cartons and wooden boxes in pallets to prevent scratches and surface damage.

    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 because it allows for quick and easy repositioning.

    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.

    Frequently Asked Questions

    Q1: What are the advantages of using a double split ring collar? A: Double split rings (two-piece) can be installed or removed anywhere on a shaft without needing to slide them from the end, making them ideal for systems where other components are already fixed in place.
    Q2: What materials do you offer for shaft collars? A: We provide collars in Carbon Steel, Stainless Steel (SUS 303/304/316), and Aluminum to suit various environmental and strength requirements.
    Q3: Do you support custom sizes or non-standard designs? A: Yes, we can manufacture non-standard sizes according to your specific requirements, ranging from 1/8" to 6" and 3mm to 150mm.
    Q4: What is the typical delivery time for bulk orders? A: For bulk goods in stock, delivery is approximately 60 days. Custom bulk goods also typically take around 60 working days, while samples take about 20 working days.
    Q5: Can you provide technical drawings if I don't have one? A: Yes, if you don't have a professional drawing, you can contact us and we will customize a design for you based on your specific application requirements.
    Q6: How do you ensure the quality of the shaft collars? A: We strictly control the perpendicularity between the surface and the bore. Additionally, we provide Material Test Reports and Quality Inspection Reports upon request.
