Amacoil offers a linear bearing slide option on drive assemblies to protect rolling ring bearings in Uhing linear drives from undue wear resulting from radial forces.
The linear slide load carrier is recommended when the tool or other payload being moved is mounted so it creates overturning moments which can interfere with the drive's function and place undesirable pressure on the bearings.
Supported on its own end supports and guide rails, the linear slide redirects twisting and bending forces. It removes them from the Uhing drive and assembly. According to Amacoil's press release, this minimizes wear on the drive bearings and other parts. Because linear slide guide rails are parallel with the Uhing drive shaft, linear movement is enhanced and the possibility of cantilevered or off-center load causing the drive to bind or seize is reduced.
With up to 800 lbs. of axial thrust, the drives can provide backlash-free linear motion in packaging and converting equipment, winding machines, spraying/coating systems and other automated industrial machinery.
Three styles are available to accommodate different payload mounting methods and varying weights. The standard linear slide model SLS and the L2 for heavy duty loads are mounted on top of the Uhing drive. A third model, the L4, mounts to the back of the Uhing drive. A load supporting surface on the L4 slide extends above the top of the drive by 1-2 mm for situations where a slide is needed but vertical space is limited.
Finally, the load carriers are flexibly coupled to the Uhing drive unit with no rigid connection. This assures that overturning moments and other forces created by the payload do not work against the axial thrust.
