PRODUCTION INFORMATION OF BALL SPLINE

Ball splines (Ball Spline bearings) are a special type of linear motion bearing that are used to provide nearly frictionless linear motion while allowing the member to transmit torque simultaneously. There are grooves ground along the length of the shaft (thus forming splines) for the recirculating ground balls to run inside. The outer shell that houses the balls is called a nut rather than a bushing, but is not a nut in the traditional sense-it is not free to rotate about the shaft, but is free to travel up and down the shaft.
 
By increasing the contact area of the ball bearings on the shaft to approximately 45 degrees, the side load and direct load carrying capabilities are greatly increased. Each nut can be individually preloaded at the factory to decrease the available radial play to ensure rigidity. This process not only increases the contact area, increasing direct loading capabilities, but it also restricts any radial movement, increasing the overhung moment capabilities. This creates a sturdier structure that can handle a very strenuous working environment.

ADVANTAGES OF BALL SPLINE
 
1.High torque
2.Low frication and noise.
3.Smooth movement.
4.Short delivery.
5.High efficiency of transferring.
 
APPLICATION OF BALL SPLINE
 
1. Engraving machines;
2. High speed CNC machinery;
3. Semi-Conductor equipment;
4. Auto-machinery.
 
Rolled ball screws can not only be used in general machinery, but also in many advanced industries. Rolled ball screw with a motor assembles electrical-mechanical actuator, which is more eco-friendly than hydraulic pump system. Nowadays it's applied to electric vehicles, solar power plants, railway decices, and many emedical and leisureequipments.
