THK’s new Telescopic Type ATG Utility Slider combines smooth motion technology with fully hardened raceways to enable high load capacity and ensure a long service life, according to the company.
The Type ATG uses THK Circular-Arc Raceway Technology for equal to or higher permissible load capacities than Gothic Arch Raceway designs. Circular-Arc Technology achieves less differential slip between the ball and the raceway, resulting in reduced cage displacement, as well as decreased friction and wear. Full stroke reliability is achieved due to the shape of the grooves.
The solid construction of the Type ATG further contributes to its increased load capacity and rigidity. The Type ATG consists of high carbon steel outer and inner profiles, high carbon chrome bearing steel balls, a steel stopper, a cold-rolled steel ball retainer, and Trivalent chromate coating on all surfaces with the exception of the balls.
The Type ATG is offered in three configurations, the ATG-S Single Type, the ATG-D Double Type, and the ATG-P Parallel Type. Rail lengths range from 130 to 770 mm and stroke lengths range from 79 to 399.6 mm. The Type ATG is compatible with competitor dimensions.
Applications for the Type ATG include automated warehouse equipment, train doors, seat sliders, and under floor equipment sliders.
The Type ATG features patented THK Caged Technology for smooth and quiet motion. Caged Technology employs a synthetic resin cage with a patented curvature that cradles each ball and separates it from the next. The spaces between the rolling elements retain grease and act as a lubrication system for long-term maintenance-free operation. Other Caged Technology benefits include increased speed and accuracy, decreased noise levels, low dust generation, and long life.
