Precision Ballscrew

Salient Features :
  

» Higher Efficiency: 
Since sliding friction is replaced by rolling friction, efficiency is greater than 90% and the driving torque is less than onethird of that of conventional screws.
» Lesser Heat Generation: 
Even high load causes minimun heating up which means an improvement of positioning accuracy.
» No Stick-slip: 
Substituting a rolling contact for the sliding metal to-metal contact minimizes starting friction and eliminates the stick-slip tendency when a slow , linear motion is required in machine tool slide applications thus resulting in a tremendous increase in tool life.
» Higher Service Life: 
Due to the rolling of balls in hardened grooves very little wear occurs over the life of Ball Screws.
» High Precision & Rellability: 
All HMT Precision Ball Screws are ground and assembled and inspected under a strict process and temperature control.
» Precise Positioning: 
High Positioning accuracy is possible even at low speeds .Maximum Axial Stiffness, Ball Screws can easily be adjusted backlash-free and pre-loaded for increasing the axial stiffness, response and repeatability of positioning.
» High Power Transmission: 
Transmission of greater forces of maximum driving power with low loss at minimum mounting dimensions.
