Product Description

Product Details

The 3 piece design consists of two flanged hubs and a center spacer, while the two-piece design comprises two solid hubs with a precision-machined bore. Both designs are typically constructed from durable materials such as steel or aluminum, with the hubs featuring precision-machined bores and keyways for secure shaft attachment.3 piece and two-piece rigid couplings are mechanical devices used to connect two shafts in a rotating system, providing a solid and inflexible link between them. Unlike flexible couplings that allow for some degree of misalignment and torsional flexibility, rigid couplings maintain strict alignment between shafts, ensuring efficient power transmission with minimal loss.


1. Precise Alignment: Both three-piece and two-piece rigid couplings maintain strict alignment between shafts, minimizing shaft deflection and angular misalignment. This precision is essential for applications where accurate positioning and synchronization of rotating components are critical, such as machine tools, pumps, and conveyor systems.

2. High Torque Transmission: Three-piece and two-piece rigid couplings are capable of transmitting high levels of torque without introducing torsional flexibility or backlash. This makes them suitable for heavy-duty applications in power transmission, rotary motion control, and industrial machinery, where reliable torque transfer is essential.

3. Easy Installation and Maintenance: The modular design of three-piece rigid couplings allows for easy installation and maintenance, as the hubs can be independently mounted and dismounted from the shafts. Similarly, two-piece rigid couplings offer simplicity in installation and removal, minimizing downtime for maintenance and repairs.

4. Compact and Lightweight: Both three-piece and two-piece rigid couplings have compact and lightweight constructions, making them suitable for installations with space constraints or weight limitations. Their minimal footprint allows for efficient use of space in machinery and equipment assemblies.
