Rotating screw jack JTA series

trapezoidal screwnutaluminum

The operation of the traveling nut minimizes the necessary space for installation in the axial direction. Structure [The explanation of the structure is for models 025 to 1250 High precision, large screw shaft This series uses a trapezoidal screw. Ideal bearing structure This series uses a tapered roller bearing and uses a thrust self-aligning roller bearing for heavy loads. High precision worm wheel This series uses a special aluminum bronze material which has been machined with high precision and offers ample strength. Traveling nut The traveling nut is crafted from a special aluminum bronze material and offers superior friction resistance. Large input shaft This series offers ample strength for the use of multiple connected jacks. High efficiency reduction This design offers the benefits of many years of experience with Worm Speed Reducer. Tough housing Models number 100 and above use cast steel for the housing and models 025 to 075 use spherical graphite (FCD450). (Cast steel production is also available.) Oil bath lubrication Oil bath lubrication makes high-speed operation possible and offers easy maintenance.
