  • High Precision Jtb Series Ball Screw Jacks - China

    price: contact company for price





    * JTB- Series Ball Screw Jacks use the same worm gear set arrangement as machine screw jacks. The addition of a high efficiency and high precision ball screw and a ball nut reduces the required input torque to approximately one- third the torque required of the machine screw jacks.

    * The worm gear driven ball screw jack incorporates a heat treatment standard # 45 steel worm which drives a high strength bronze worm gear set and a ball nut. The worm shaft is supported on anti- friction deep groove ball bearings with external seals provided to prevent loss of lubrication. Lubrication with synthetic grease ep2 lithium grease. The bronze worm gear set and a ball nut is supported on anti- friction ball thrust bearings. Rotation of the bronze worm gear and a ball nut causes the lifting ball screw to translate or rotate, depending upon jack configuration. The jack housing is made of ductile iron and proportioned to support the rate capacity of the unit. The lifting ball screw is made of high strength hardened ball bearing steel, This rolling action reduces friction between the ball nut and the lifting ball screw permitting smooth and efficient movement of the load. Because of the greater efficiency and rolling action, the lifting ball screw can operate at higher speeds and higher duty cycle when compared with the machine screw jacks. When a JTB- Series Ball Screw Jacks is motorized, less horsepower is required than an equivalent size machine screw jacks.

    * JTB- Series Ball Screw Jacks major configuration devides the jacks into translating ball screw jacks, lifting nut rotating ball screw jacks, anti- rotation keyed ball screw jacks ( with square tubes) , anti- backlash ball screw jacks, double clevis ball screw jacks etc. Upright and inverted type ball jacks. Standard lifting ball screw end types such as top flange ( top plate) , clevis end ( male clevis) , threaded end and plain end, also can custom to make kinds of lifting ball screw ends.

    * JTB- Series Ball Screw Jacks without self- locking, will backdriving after attached loads, and need brake mechanism or locking system for holding the loads. Lifting force from 1 ton to 35 ton. Single lead and high lead ball screw are available. Linear speeds up to 6.75 m/ min. Can be driven by motors, hand wheels or both together, 8 sizes in two gear ratios for high and slow linear speeds. Can be mounted in any attitude. Generally maintenance free.

    * JTB- Series Ball Screw Jacks are used wherever controlled lifting, lowering, pushing and pulling is required. They can be installed single unit, in pairs or multiple units ball screw jack lifting systems simultaneously lifting. Accessories such as electric motors with brake, hand wheels, digital counters, flex couplings, bevel gearboxes, bellow boots, limit switches, drive shafts, pillow blocks, flange blocks, stop nuts, gear motors with brake, worm gear reducer with brake, rod ends etc.

    * JTB- Series Ball Screw Jacks Application in cnc cut to length machine, feeder leveler, multi storied car parking, aluminium composite panel production time, robotics arm raising, food processing oven cooking system, bradbury stacker, vacuum furnace lid lifter, calendar stack, palletizer, extrusion machine, hydraulic cylinder replacement, blow molding machine, motorized self- raising tower system, Stage height adjustment, Mobile lifting platform for heavy vehicles, Centring mechanism using right and left threaded screws, Device for aligning steel sections, Adjustment system for bearings in the textile industry, Compact press, Angular adjustment of a plate saw, angle tilt adjustments with double clevis, cnc steel shearing machine, aircraft maintenance platform, tundish car, test rigs, clamping mechanism, conveyor tracking, airbridges, lifting stretchers, aircraft maintenance platform, solar positioning system, pallet lifting, laddle turning mechanism, railway carriage lift, construction paint system, aircraft docking system, material handling, positioning conveyer belt, auto manufacturing, food processing, paper production, carpet shearing, power station operation, waste recycling, metal processing, glass packaging, foam production and metallurgy industry, mining industry, chemical industry, construction industry, irrigation industry.
