telescopic common joints usually with twice joints with bearings or needle bearings together with a sliding splined centre section allowing adjustment between two shaft. Length adjustment should be made statically without torque load.
Why we call the idea telescoping cv joint, because its length can variable, same as a telescopic, consequently some customer call this adjustable felxible universal shared for cardan shaft as well as extendable universal joint. System feature:
1. It would work for the transmission when using the axis angle β<45°of each axis
 2. connect extra longer shaft space
 THREE OR MORE. Finished product hole tolerance H7, keyway, hexagonal pit and square hole might order as requirement.
FIVE. installation length L and also X:
X≤(Lmax-2. L2-B)/2
 Lmin≥(Lmax+2. L2)/2 Lmin=L2+B+X+L2
 Proclaimed as: WSP-3GA-Y20-Y20-550/650
 WSP-3G: specification along with item no
 Y20: traveling end hole style as well as size
 Y20: driven stop hole style and dimension
 550/650: installation Lmin/Lmax
 Let see drawings belonging to the extendable universal joint
 You can easliy offer many different dimensions even 1 inch general joint or as clients' requirement. customzied universal jont.
Program:
leveling machine,
woodworking unit,
packing machine
 Glass device, etc.
How to choose an appropriate coupling:

If you have diverse hole and size with the size chat, we could also make same as customer’s prerequisite, such as parallel pins, keyway、hexagon pin square hole。
 1. Based on mechanical requirements, such because transmission torque, stiffness requirements, vibration, impact, acid as well as alkali corrosion resistance, tranny accuracy.
2. If possess different torque and ditch, pls offer design mapping and sample, with accept customise, no matter is rapidly release or with flange or needle bearing type.
SEVERAL. The universal coupling is definitely widely used in numerous general mechanical because connected with its large deviation position and high transmission torque.
SEVERAL. Coupling usually have all those type: universal type, high speed type, micro type, extension type, large torque general coupling etc.
Foshan Houzhe Tranny Equipment Co.,Ltd. seemed to be founded in 2002, the company's headquarters and factory is situated in Dali town,which is recognized as the "Guang fo Gold Corridor", only 30 minutes in the airport by car, its far more convenient for transportation in addition to marketing. In addition into the factory, we also create a branch in Shanghai as well as operating in good issue. Our factory covers a place of 2000 square meters. At present, there become more than 50 sets special manufacturing and testing apparatus with an annual output more than 1 million universal couplings, our business scope covering more than 100 countries and parts domestic and abroad.

Were a company integrating UR & D, produce, product sales and service, we consentrate on the R & VE HAD and design of hardware transmission equipment. We have absolutely advantages in your industry. Our product with higher precision than marketplace level, and the accuracy may be reached 0. 001mm, while other small factories can't compare with us. We already has our own brand "HZCD".
