Ball screws Ball screws are used in aircraft and missiles tomove control surfaces, especially for electric fly by wire, and inautomobile power steering to translate rotary motion from an electricmotor to axial motion of the steering rack. They are also used inmachine tools, robots and precision assembly equipment. High precisionball screws are used in steppers for semiconductor manufacturing.Material:metalProduct Name:Ball ScrewColor:silverLinear Rail Guide+Sliding Block Linear bearing is a low-cost production of linear motion system for unlimitedtravel in conjunction with the cylinder axis. Because of point contactbetween ball and straight axis, so the load is small. The ball isspinning with the smallest friction, it can run a high precision andsmooth motion.This is the sliding unit with the aluminium case,shafts and aluminium rail for preventing deflexion. This is the completesliding unit systems and can be clamped simply tightening by bolt withhigh accuracy. The support rail unit provides maximum rigidity andstiffness to the shaft throughout the whole stroke, and ensure theperformance of the unit.Package Included : 2 x SBR12-1000MM4 x SBR12UU1 x SFU1204-1000MM with Ending Machined1 Set BK10/BF101 x Shaft Coupler BR 6.35mm x 8mm D20L25We can customize the lengh whatever you want, pls contact us before buying.
