Ball Spline

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.

Technical Support


Caged Ball Spline SLS/SLF

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.

SLS/SLF


High Torque Model LBS

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 .

LBS, LBF, LBH, LBST, LBR


Medium Torque Model LT

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.

Rotary with Gears Model LBG

Rotary with Gears Model LBG

 

This model is a unit type that has gear teeth on the flange circumference, and radial and thrust needle bearings compactly integrated on the spline nut. This Ball Spline is optimal for a torque transmission mechanism with spline nut drive.
