New thk lbs 20 tuu rolling guide spline bearing
USED IN A WIDE ARRAY OF APPLICATIONS SUCH AS:
* COLUMNS AND ARMS OF INDUSTRIAL ROBOT
* AUTOMATIC LOADER TRANSFER MACHINE
* AUTOMATIC CONVEYANCE SYSTEM

THIS THK LBST IS A HEAVY LOAD TYPE THAT HAS THE SAME SPLINE NUT DIAMETER AS MODEL LBS, BUT HAS A LONGER SPLINE NUT LENGTH. IT IS OPTIMAL FOR LOACTIONS WHERE THE SPACE IS SMALL, A LARGE TORQUE IS APPLIED, AND AN OVERHANG LOAD OR MOMENT LOAD IS APPLIED.
THIS IS AN INNOVATIVE PRODUCT WITH A BALL ROLLING ON A GROOVE CONNECTED TO THE SHAFT, REALIZING ALLOWABLE LOADES GREATER THAN WITH LINEAR BUSHING AND ENABLING TORQUE TRANSMISSION WHILE MAKING LINEAR MOVEMENTS. UNLIKE THE CONVENTIONAL STRUCTURE, A SINGLE SPLINE NUT CAN PROVIDE A PRELOAD WITH THK'S BALL SPLINE. AS A RESULT, THE BALL SPLINE DEMONSTRATES HIGH PERFORMANCE IN ENVIRONMENTS SUBJECT TO VIBRATIONS AND IMPACT LOADS, LOCATIONS WHERE A HIGH LEVEL OF POSITIONING ACCURACY IS REQUIRED OR AREAS WHERE HIGH SPEED KINETIC PERFORMANCE IS REQUIRED. IN ADDITION, EVEN WHEN USED AS AN ALTERNATIVE TO A LINEAR BUSHING, THE BALL SPLINE ACHIEVES A RATED LOAD MORE THAN 10 X GREATER THAN THE LINEAR BUSHING WITH THE SAME SHAFT DIAMETER, ALLOWING IT TO COMPACTLY BE DESIGNED AND USED IN LOCATIONS WHERE AN OVERHUNG LOAD OR A MOMENT LOAD IS APPLIED. THUS, THE BALL SPLINE PROVIDES A HIGH DEGREE OF SAFETY AND LONG SERVICE LIFE.
