Original THK ball spline 2LBST40UUCLFM+400LF, high torque model LBS, with heavy load capacity, full ball type.
Overview of THK ball spline:
The Ball Spline is a rolling guide spline bearing. This is an innovative product with a ball rolling on a groove connected to the shaft, realizing allowable loads greater than with linear bushing and enabling torque transmission while making linear movements.
Classification of Ball Spline:
1. Caged Ball Spline SLS/ SLF
The adoption of the ball cage enables the circulating motion of evenly spaced balls to be maintained and highspeed response to be achieved. In addition, it eliminates collision and mutual friction between balls, and realizes low noise, pleasant running sound and low particle generation. As the grease retention is increased, long-term maintenance-free operation is also realized.
(Model number)
SLS/ SLF
2. High Torque Model LBS
This Ball Spline has no angular backlash to increase the rigidity by providing a preload with one spline nut since the spline shaft has 3 crests equidistantly arranged at 120 degrees on the circumference, each held by 2 rows (6 rows in total) of balls under a load .
(Model number)
LBS, LBF, LBH, LBST, LBR
3. Medium Torque Model LT
This Ball Spline has a large load capacity in the radial and torque directions since the spline shaft has 2 to 3 crests on the circumference, each held by 2 rows (4 or 6 rows in total) of balls under a load in order to reasonably provide a preload.
(Model number)
LT, LF
4. Rotary with Gears Model LBG
(Model number)
LBG, LBGT
5. Rotary Model LTR
(Model number)
LTR, LTR-A
