INVOLUTE SPLINES

Involute Splines are precision-machined mechanical elements used for transmitting torque between mating shafts while allowing axial movement. The splines consist of a series of equally spaced grooves in the shaft and matching teeth in the mating part, shaped in an involute profile for optimal contact and load distribution.

At FloFit Enterprises, we produce high-precision involute splines to meet the demands of industries requiring accurate alignment, robust torque handling, and interchangeability.
