Ball Screw jack0 pages

The ball screw jacks proposed in the K series are born from UNIMEC’s experience in
trapezoidal screw jacks.
The can be employed for lifting, pulling, moving, aligning any kind of load with a perfect
synchronism, which is difcult to obtain by means of other handling devices. The K series
screw jacks are suitable for high services as well as for a very rapid, quick and precise
positioning. As compared to trapezoidal screw jacks, the K series presents a transmission
reversibility: it is therefore advisable to provide for brakes, blockings or contrast torques
in order to avoid a direction reversal. Screw jacks can be applied singularly or in groups
properly connected with shafts, joints, and/or bevel gearboxes.
They can be driven by different motors: electrical, with either alternating or direct current,
as well as hydraulic or pneumatic motors. Also they can be driven manually or with any
other kinds of transmission. UNIMEC ball screw jacks are designed and manufactured
using innovative technology so to supply a product which identies itself with the state of
the art in the transmission devices.
Ball screw jacks
The highest quality and a 28 years long experience are able to meet the most demanding
and sophisticated requirements.
The special hollow shaft mounting allows to assemble any kind of ball spindles available
on the market, making the K series really universal. The outer surfaces are completely
machine nished and the parts are assembled with special care, in order to allow the
application of supports, anges, pins, or any other components a mounting may require.
Special sealing systems enable the inner gears to operate in a bath of lubricant, which
guarantees them a long lasting life.
Moreover the following models, UNIMEC can realize any special transmission a design
may require.
