Product Description

The Ball Spline is a rolling guide spline bearing. It 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.

Medium torque type-LT-LF
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.

Application:
Die-set shaft and similar applications requiring straight motion under a heavy load;
Loading system and similar applications requiring rotation to a given angle at a fixed position
Automatic gas-welding machine spindle and similar applications requiring a whirl-stop on one shaft
Column and arm of industrial robot
Spot-welding machine
Riveting machine
Book-binding machine
Automatic filler
XY recorders
Automatic spinner
Optical measuring instrument

Cylinder type-LT Nominal diameter 4~100mm

How to select a ball spline?
1. Setting conditions
Stroke length, velocity, magnitude of the applied load, mounting space, operating frequency, required service life, dimension(No. of spline nuts, span), installation direction, environment, accuracy.
2. Selecting a type
High torque type-LBS/LBST/LBF/LBR/LBH
Medium torque type-LT/LF/LT-X
Rotary type-LBG/LBGT/LTR/LTR-A
3. Studying the spline shaft strength
Estimating the spline shaft diameter/length, permissible load on the spling shaft, displacement of the spline shaft(deflection, torsion), method for fixing the spline shaft.
4. Predicting the service life, compared with the required service life.
5. Selecting a preload
6. Determining the accuracy
7. Selection according to the environment
