Structural Types of Universal Joints

Feb 14, 2015 Technical Articles

(1) UC Series

Bearings of universal joints are not fixed with bolts in case they become loose or even fractured. Therefore, UC series are applied for improving strength of these weak points, prolonging service life and facilitating maintenance. Based on different requirements, UC series has 7 structure types.

Structure Name	Structure Code	Structure Drawing
Standard Telescopic Type	B
Standard Telescopic Flanged Type	F
Short telescopic Welded Type	D
Long Telescopic Welded Type	L
Non-stretch Welded Type	W
Non-stretch Flanged Type	X
Non-stretch Short Type	Y

(2) UP Series

For universal joints, bearings are quick-wear parts. UP series are created in consideration of this. Glands are made into partitions for easily changing bearings in a better way. In UP series, there are total 11 structure types in view of different requirements.

Structure Name	Structure Code	Structure Drawing
Telescopic Long Type	B
Telescopic Short Type	D
Non-stretch Short Type	Y
Non-stretch Long Type	W
Telescopic Double Flanged Long Type	F
Big Telescopic Long Type	L
Telescopic Ultra Short Type	C
Shaft Sleeve and Fork of the Positive Assembly and Cut-through Type	GA
Shaft Sleeve and Fork of the Reverse Assembly and Cut-through Type	GB
Shaft Sleeve of Reverse Assembly and the Fork of Positive Assembly and Cut-through Type	GC
