SFT Taiwan Cross Roller Guide

Founded in 2010, SF Technology is a leading manufacturer of precision motion components and a motion control solutions provider, marketed under SFT brand. Cross Roller GuideCross roller guide is a non-circulating, curved cross roller slide way, and the precision rollers that have extremely low friction resistance provide a stable arc movement. They are mainly used in high-precision positioning where rotation centers remain unchanged and accurate tilting angles are required. They are widely used to meet the purposes of optical instruments and measuring devices.Cross Roller Slide RailThe SFT Cross Roller Slide Rail is a linear motion rolling guide that incorporates a roller or ball cage between two linear slide rails with V-shaped surfaces that act as track grooves. Each slide rail are precision grinded and made with hardened steel and cryogenic finish. It is suitable for limited stroke linear motion system with low friction, light load and high accuracy.Slide Rail Set 1 set = 4 rails + 2 retainers + 8 end screws.Positioning Stage: Cross Roller GuidingThe positioning stage for crossed roller bearing guilding is composed of moving rails with 2 V-groove surfaces harden finish, ground precisely,and roller bearings which are connective and take turns moving in 90 degrees to meet requirement of high parallism and high flatness.In structure, V-groove and crossed roller acquire movement in high accuracy and capacity by linear transmission to act a high precision movement and load capacity performance.Positioning Stage : Linear Ball GuidingSlide way and body of the linear ball stage is in one unit, and Gothic arc-groove ground precisely to meet requirement of high parallism and high flatness.Gothic arc-groove formed by dual arc-grooves individually on upper and lower rails of body. Ball moving in single groove is structured by 2 point-contact, and total 4 contact point in dual arc-groove to form strong rail construction.In case of rails of SUS-STAGE is to set ball assembly in arc-groove to save traditional adjustment and revision time. In addition, without adjustment screw would save accuracy problem and maintenance time caused by loosen screw, and cheaper as well.Positioning Stage : Dovetail GuidingThe dovetail stage is applied to optical instruments and equipments, sampler, detecting device, semi-conductor manufacturing equipment, test machine, micorscope, transiting machine, maching center, medical instrument, printer and others.Cross Roller BearingCross roller bearings consist of inner rings, outer rings, spacer retainers and cylindrical rollers cross arranged on the V-shaped 90° groove between the inner and outer rings. This structure can withstand radial, axial and moment loads in all directions because the rollers'line contact with raceway surfaces achieve a large load-bearing area despite the minimum dimensions. Therefore these bearings are widely used on the rotating parts of industrial robots, machine tools, precision rotary tables, measuring instruments and IC manufacturing machines.
