Beam Couplings

Beam couplings are characterized by their ability to handle small angular and parallel misalignments, typically up to 0.025 inches and 7 degrees, respectively. They are particularly suitable for motion control applications where precise positioning is crucial, such as in robotics and CNC machinery. When considering a beam coupling, buyers should evaluate the torque capacity, which is usually limited to less than 100 inch-lbs. Their lightweight construction and low cost make them an appealing option for many applications, but they may not be suitable for high-power transmissions.

Bellows Couplings

Bellows couplings are designed for high torsional stiffness, making them ideal for applications that require precise positioning, such as robotics and CNC machines. They consist of multiple metal convolutions that can tolerate some misalignment but are more rigid compared to beam couplings. B2B buyers should consider the application requirements for torsional stiffness and torque capacity, as these couplings are typically more expensive than others. Their advantages include excellent precision and durability, but they may not be the best choice for applications with significant misalignment.

Chain Couplings

Chain couplings are robust and flexible, allowing for significant angular and parallel misalignment. They are commonly used in heavy machinery and conveyor systems, where high power transmission is necessary. Buyers should note that while chain couplings can handle substantial torque loads, they require regular maintenance to ensure optimal performance. Their durability and ability to accommodate misalignments make them a popular choice, but the bulkiness and maintenance requirements can be downsides for some applications.

Jaw Couplings

Jaw couplings consist of multi-jawed hubs that connect with elastomeric spiders to dampen vibrations and allow for slight misalignments. They are widely used in pumps, compressors, and light machinery. B2B buyers appreciate their low backlash and ease of installation, but they should also consider the limitations in angular misalignment, which can be less than 1 degree. Overall, jaw couplings provide a good balance of performance and cost-effectiveness for many applications.

Diaphragm Couplings

Diaphragm couplings utilize a flexible membrane to accommodate misalignment while transmitting torque. They are often found in aerospace and automotive applications due to their high torque capacity and excellent vibration dampening properties. Buyers should be aware that diaphragm couplings typically come with a higher initial cost and may require more complex installation processes. However, their ability to handle high loads and reduce vibrations makes them a valuable investment for critical applications.
