Simple understanding of the types and specialties of ball splines

With the development of industrial automation and the strong promotion of innovation in China's policies. Manufacturing has reached a historic peak, leading many manufacturers to imitate and more and more enterprises are engaged in this field. Causing market chaos, taking CNC machine tools and four axis robotic arms as examples, there are many types of ball splines used in these industries, and the equipment is also different. So how to distinguish and judge?
The first point is the type of spline outer cylinder
Cylindrical ball spline SLT/SOT type
The outer diameter of the spline outer cylinder is a straight cylinder type, which is one of the latest types of installation space when the key is tapped in for torque transmission.
Point 2: Circular flange type ball spline SLF type
Using flanges and bolts to fix the outer cylinder on the support base is most suitable for use on the support base due to its simple assembly. When used in situations where there is a risk of deformation during keyway machining or where the width of the support seat is relatively narrow, it can completely prevent the rotational clearance generated by the mating part.
Thirdly, strengthen the dustproof flange type ball spline SZF type at the end
Enhanced dust-proof design can effectively isolate foreign objects from entering the ball spline cylinder, suitable for environments with high levels of fouling.
Fourth point, method: Blue ball spline SOF type
Using flanges and bolts to fix the outer cylinder on the support base, it is suitable for use in industries such as 3C and semiconductor due to its simple assembly.
Fifth point, spline shaft type
Precision solid spline shaft (standard S-type)
By precision grinding the rolling grooves of the spline shaft, high precision is achieved and then matched with the outer cylinder.
Point 6: Hollow spline shaft (H-type)
Hollow spline shafts can be used in places where piping, wiring, exhaust, or weight reduction is required.
Point 7: Special spline shaft
When the diameter of the spline shaft end or middle part is relatively large, the spline part is made by special processing.
Through the above explanation and description by our technical engineers, we hope to help manufacturers have a clear understanding when purchasing and installing ball splines. There are many types of products that are applied in different equipment industries. Therefore, when making a purchase, it is important to pay more attention and choose what is suitable for oneself.
