Ball Screw with Single Nut Flange End Cap SFE

Ball Screw with Single Nut Flange End Cap SFE
ISUTAMI SFE ball screw with single end cap flange nut assembly is an outer circulation nut ball screw combination. The steel ball is extracted from the groove of the screw shaft into the through hole of the nut by the end cap, and returns to the groove via the through hole to perform an infinite circular motion. The end cap return works very much like the through-the-nut return, except that the ball deflector function is performed using a plastic cap at both ends of the ball nut, each cap serves as a ball return and also includes wipers. End cap return is typically used for very large lead/diameter ratios. This type of ball nut is only available as a flange nut.

Ball Screw with Single Nut Flange End Cap SFE Features

The ball screw return system is designed to pass through the front and rear circulation paths, and the through holes on the nut are used as the steel ball returning, so that all the beads on the nut are covered with effective steel balls. Therefore, at the same nut length, the end plug nut one will have a higher dynamic load than the outer circulation nut. Cold rolled formed ball screws are ideal for applications that do not require the finite accuracy of the ground ball screw equivalents, but are still required to reliably transmit a linear load with a high degree of repeatable accuracy.

The end cap type outer circulation is an early structure, which is characterized by simple structure, easy to assembly and disassembly, with good processability and reliable function, and is suitable for the application fields of general industrial machinery and automatic machinery.
