    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.

    Threaded Shaft Collars

    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 for easy identification.
    • Black oxide treatment creates retention and resists corrosion.
    • Available in black oxidized steel, galvanized steel, stainless steel, aluminum, and more.
