earth station antennas jackscrew actuator, jackscrew elevation drive earth station antennas, earth station antennas jackscrew drive mechanism, antennas moved in the X and Y axises using electric motor driven jack are widely used in 4.5m earth station antennas, 6.2m earth station antennas, 7.3m earth station antennas, 9m earth station antennas for azimuth and elevation, which is the perfect solutions for satellite dish antenna tracking system withstanding wind force and weather, self locking function, precision positioning, maintenance free, long service life. Notes, when electric ball screw jack, must be equipped with brake motor or other lock mechanism. Important Components: 1. Self-locking worm gear screw jack linear actuators with motor flange adapter. 2. AC gear motor, worm gear reducer, helical bevel gear reducer or other gear reduction mechanism. 3. Limit switches or travel limiter for control full extend and retract travel stroke, which installed on steel protective pipe cover. 4. Steel protective pipe cover for anti-rust and anti-dust under worm gear screw jack base, when full retract stroke. 5. Bellows boots for anti-rust and anti-dust upper screw jack base, when full extend stroke. 6. Swivel plate, swivel trunnion mounting base, pivoting frame for tracking sun of pivot solar panel with other loads. 7. Manual drive screw jack linear actuators can be operated manually, or arrangement an electric motor operated screw or gear system. Other Features: 1. Upright type installation, compression load and tension load. 2. Translating screw with female thread cylinder rod clevis end with pivot pins. 3. Anti-rotation keyed screw with male thread end matching female ball joint rod end bearing. 4. Low speed gear ratio screw jack with gear reduction mechanism gear motor. 5. Lifting screw total length = required stroke + bellows full retract length + jack housing height + screw top end length + swivel plate or swivel trunnion mounting base height. 6. Lifting speed about 100 mm/min to 300 mm/min, it depends on customers requirements. “JACTON” Brand Products: “JACTON” brand products include worm gear screw jack, trapezoidal screw jack, ball screw jack, bevel gear screw jack, worm gear linear actuator, right angle spiral bevel gear box, screw jack lift system etc.
