Prowadnice z wałkiem profilowanym, przenoszące moment skrętny
LBS
Ballspline
A medium duty cylindrical ball spline
Zero angular backlash
High rigidity and accurate positioning
Compact design, simple assembly
High speed linear motion and rotation possible
LT and LF
Ballspline
LT and LF Ballsplines have 4 or 6 trains of load bearing balls to hold 2 or 3 crests on the spline shaft from both sides, so that an appropriate preload is applied without trouble
The balls are held in place by the retainer, causing the balls to circulate and preventing them falling off if the spline shaft is removed
High load-carrying capability
Zero angular backlash
High rigidity and simple assembly
LTR
Rotation-Ballspline
The LTR has six trains of load bearing balls to hold three crests on the spline shaft from both sides, so that an appropriate preload is applied easily.
Angular-contact raceways that constitute a support bearing are formed on the exterior of the spline nut, making this type compact and lightweight
Zero angular backlash
Simple assembly and high rigidity
Major uses: Scalar robot Z axis, Wire winder, Machine center ATC, Assembling robots
