Output Shaft/Stem Adapter: Max RPM 1000-5000 RPM

Component Specifications

Definition

A precision mechanical component designed to interface between an actuator's output mechanism and the driven equipment's input shaft or stem, ensuring proper torque transmission, alignment, and connection integrity in automated industrial systems.

Working Principle

Converts rotational or linear motion from the actuator output to the driven equipment through mechanical coupling, maintaining precise alignment and torque transmission while accommodating minor misalignments through flexible or rigid connection designs.

Materials

Typically manufactured from alloy steel (AISI 4140/4340), stainless steel (304/316), or aluminum alloys (6061-T6) with surface treatments like hardening, plating, or coating for wear resistance and corrosion protection.
