needle bearing micro precision double telescoping universal joint

telescopic universal joints usually with double joints with bearings or needle bearings plus a sliding splined centre section to allow adjustment between two shaft .Length adjustment should be made statically without torque load.
Why we call it telescoping cv joint ,as its length can adjustable ,same as a telescopic ,so some customer call it adjustable felxible universal joint for cardan shaft or extendable universal joint .

We can offer many different size even 1 inch universal joint or as customers' requirement .customzied  universal jont .

Application :

leveling machine,

woodworking machine,

packing machine

Glass machine, etc.  

How to choose a suitable coupling:

If you have different hole and size from the size chat ,we also can make same as customer’s requirement ,such as parallel pins,keyway、hexagon hole square hole。

1. Based on mechanical requirements ,such as transmission torque, stiffness requirements, vibration, impact, acid and alkali corrosion resistance, transmission accuracy .

2. If have different torque and hole,pls offer design mapping and sample ,with accept customize, no matter is fast release or with flange or needle bearing type.  

3. The universal coupling is widely used in all kinds of general mechanical because of its large deviation angle and high transmission torque.

4. Coupling usually have those type : universal type, high speed type, micro type, extension type, large torque universal coupling etc.
