By fixing both motors to a base plate, this actuator shifts reaction forces off the housing, cutting reinforcement needs, cost, and fatigue.

Redirecting load through a rigid connection and mounting plate relieves guide stress, improving synchronous lifting reliability and squeeze protection.

A spring-loaded eccentric disc and cam spring shift furniture drive coupling sleeves abruptly, cutting clutch wear in frequent adjustments.

A nested hollow spindle and profile tube layout improves mounting flexibility and lowers actuator installation cost in height-adjustable tables.

A spindle-mounted oval cover rotates against impinging walls to keep the slot closed and prevent finger crushing during adjustment.

A gas spring and linked lever arms counter gravity to control wall bed motion and hide support legs when stored vertically.

A coaxial motor and eccentric replace noisy gear trains to automate smooth, continuous rocking for chairs, cradles, and wheelchairs.

Clevis-pin linkage joints and slot-prong motor mounts cut fasteners, simplify furniture actuator assembly, and reduce production cost.

An external tool connection lets a dual bed actuator manually lower back and leg sections during power failure without battery drain.

A slidable receptacle and positioning member simplify synchronizing bar installation, improve alignment, and ensure reliable drawer ejector triggering.

A rotating oval cover keeps the table slot closed as the spindle slides, preventing finger insertion and crushing during adjustment.

A dual-arm lever links seat depth adjustment and footrest folding to save space while enabling upright and reclined seating positions.

Integrated vertical and horizontal adjusters with a pivot let radar mounts be aligned and readjusted precisely using one tool.

A locking slide bar and cam-spring layout enable fast resistance zone changes plus fine chair pivot tuning for different user weights.

An eccentric gear train lets workpiece holders rotate continuously with selectable transmission ratios, improving vacuum coating quality.

An actuating bar and wrap spring clutch simplify linear bed drives and enable quick, reliable lowering during power failure.

A spindle-linked sliding potentiometer gives furniture linear actuators absolute end and intermediate position feedback without complex end-stop switches.

A detent-and-spring latching mechanism lifts and releases casters with repeated one-direction input while keeping multiple linkages synchronized.
