Single Split or double split Screw Collar Black Finish

Single Split or double split Screw Collar Black Finish but important, machine component found in many power transmission applications. The collars are used as mechanical stops, locating components, and bearing faces.

    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.


    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 or replacement of shaft mounting components.


    Double split rings are commonly used in a variety of industrial and mechanical applications, including machinery, conveyor systems, power transmission equipment, and other systems that require precise shaft positioning and component retention. They are available in different materials such as steel, stainless steel and aluminum to suit specific application requirements.


    Overall, double split rings provide a convenient, efficient solution for securing and positioning components on a shaft while being easy to install and remove, making them a valuable component in many mechanical and industrial environments.

    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.

    Collars are available in black oxidized and galvanized steel, stainless steel, aluminum and other materials.

    Whatever your application needs, we have the right collar to ensure your mechanical system runs smoothly and performs reliably.
