SLF flange type ball spline installation size preview table:

Ball spline is composed of spline shaft, spline nut, and steel ball. TBI ball spline is the most commonly used transmission component in machine tools and precision machinery. Its main function is to convert rotational motion into linear motion or torque into axial repetitive force, while also possessing the characteristics of high precision, reversibility, and high efficiency.

TBI ball spline has the following advantages:
(1) High load capacity
The rolling groove of the ball is precision ground and formed, and adopts Gothic 40 ° angle contact. Due to the large contact angle, it has a large load capacity in both radial and torque directions.
(2) High rigidity
Due to the large contact angle, it has high rigidity and can achieve high torque rigidity by applying appropriate preload depending on the situation.
(3) The clearance in the rotation direction is zero
By using 2-4 rows of relative ball bearings with a contact angle of 40 °, the spline shaft is combined with the spline bearing sleeve (spline nut), and the clearance in the rotation direction can be zero by adjusting the preload method.
(4) Sensitivity of Height
Due to the special design of the steel ball contact point, in addition to high rigidity, it is more sensitive and can reduce energy waste.
(5) Easy assembly
Due to the special design, even if the spline bearing sleeve is detached from the spline shaft, the ball will not fall off. Therefore, assembly, maintenance, and inspection are all very easy to carry out.
