1-3/8 x 1-3/8" Shaft Lovejoy® Series U-137 Uniflex Coupling U137R-CP-1-3/8X1-3/8

The U type is the basis for all Uniflex couplings.

The "R", or "S" in the part number indicates whether it is a "regular length", or "short length.

It is a shaft-to-shaft flexible coupling with a simple one piece design, making it ideal for indexing, robotic or positioning applications.

The U type consists of a triple-wound flexible steel spring brazed to a steel hub at each end.

This all steel design ensures optimum equipment protection in severe environments and/or high temperature applications.

Regular and short versions are available for most sizes to accommodate different overall length requirements.

Special hub or bore modifications are also possible.

These units can be supplied with either pin holes or with keyways and set screws.

Lovejoy does not recommend the reboring of uniflex couplings by customers due to potential damage to the brazed joint.

This is a durable one-piece flexible coupling for general purpose shaft-to-shaft applications.

It is the basis for all Uniflex coupling types.
