LTR-a Rotary Ball Spline/Linear Motion Spline/Linear Ball Spline with Support Bearing

  • Model NO.: LTR8A/10A/16A/20A/25A/32A/40A
  • Specification: N/A
  • HS Code: 8483401000
  • Trademark: N/A
  • Origin: Cn
Quantity:
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.
 
 
Rotary type-LTR LTR-A
This model is a compact unit type of Ball Spline whose support bearings are directly integrated with the outer surface of the spline nut.

Application:
Z axis of scalar robot
Wire winder

Rotary type-LTR8A/LTR10A/LTR16A/LTR20A/LTR25A/LTR32A/LTR40A

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
