Coupling FAQs:


Q: Is coupling a device used to connect two shafts together at their ends for the purpose of transmitting power?

A: Yes.

Q: Is coupling a mechanical device for transmitting torque between two shafts that are not collinear?

A: Yes.

Q: Are couplings usually used to transmit torque from one shaft to another when the two shafts are slightly misaligned?

A: Yes.

Q: Are couplings normally balanced at the factory prior to being shipped?

A: Yes, but they occasionally go out of balance in operation.

Q: Is coupling that assembling or disassembling of the coupling is possible without changing the position of the shaft?

A: Yes.

Q: Are couplings generally limited to angular misalignments, i.e., the angle of the spindle relative to the axes of the connected shafts, of 4-5°?

A: Yes, Universal joints are capable of higher misalignments.

Q: Are couplings to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both?

A: Yes.

Q: Is coupling used for heavy power transmission at moderate speed?

A: Yes.

Q: Is coupling lubricated?

A: Yes.

Q: Are couplings also known as Box Couplings?

A: Yes.

Q: Is coupling used to connect shafts which having a small parallel misalignment?

A: Yes, and angular misalignment or axial misalignment.

Q: Are couplings designed for heavy loads or industrial equipment?

A: Yes.

Q: Is coupling composed of two shaft hubs?

A: Yes, and a metallic grid spring, and a split cover kit.

Q: Are couplings also used to connect two nominally coaxial shafts?

A: Yes.

Q: Are couplings used in machinery for several purposes?

A: Yes.

Q: Is coupling the possibility to incorporate features into the final product while still keep the single piece integrity?

A: Yes.

Q: Are couplings used when precise shaft alignment is required?

A: Yes, shaft misalignment will affect the coupling's performance as well as its life.

Q: Is coupling placed on each shaft so the two flanges line up face to face?

A: Yes.

Q: Is coupling mostly used to couple electric motors and machines?

A: Yes.
