China Suppliers Factory Single and Double Split Screw Collars with Black Finish for Power Transmission Applications
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.
Double Split Ring Features
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.
⚙️ Secure Grip
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.
🔄 Easy Adjustment
Often used in applications requiring frequent adjustments because it allows for quick and easy repositioning or replacement.
