Dust prevention design of ball spline

Ball spline lubrication for dust prevention
To prevent foreign objects from entering the ball spline nut or lubricant leakage, a special synthetic rubber sealing ring with strong wear resistance is selected for the dust ring of the ball spline nut. Please replenish the corresponding lubricating grease as necessary according to the usage situation. In addition, the replenishment time of lubricating grease varies depending on the usage conditions. Generally, when using it, the lubricating grease should be replenished or exchanged based on a running distance of 100km (6 months to 1 year).
1. Without a sealing ring, please apply lubricating grease inside the spline nut or in the rolling groove of the spline shaft.
2. High quality lithium soap based grease No. 2 is installed inside the spline nut with a sealing ring (UU type seal at both ends and seal at one end). When operating at high speed or during long travel, please inject the same type of grease into the lubrication hole of the spline nut again after trial operation before starting the mechanical equipment.
The selection of shafts (solid shaft, hollow shaft), when the diameter of the ball spline shaft end or middle part is large, will be cut according to the customer's needs. For areas that require piping, wiring, exhaust, or weight reduction, hollow spline shafts can be used in combination.
Each groove on the spline shaft is precisely ground to form a perfect 40 ° angular contact point. The concept of a 40 ° contact design is to increase the load-bearing capacity and stiffness in order to withstand greater torque loads.
Zero angle gap/gap
Each groove on the spline shaft is precisely ground to form a perfect 40 ° angular contact point, known as a Gothic arch. Gothic design eliminates gaps that may cause deflection, making it the most suitable for applications that require the highest precision.
high sensitivity
The unique 40 ° angular contact design is designed to drive with minimal friction, while also providing the highest sensitivity and rigidity.
High rigidity
The combination of a wide contact angle and appropriate balanced preload force can provide high torque and torque stiffness. Installed in the design
The ball spline is low and has a simple design, so it can be disassembled even if necessary. Due to the ball retention design, when the spline shaft needs to be removed, the steel balls will not separate like traditional nut designs
