Selection Guide of JTS Series Bevel Gear Screw Jacks

Find out more about how to correctly select a complete part number of JTS Series Bevel Gear Screw Jacks?
According to the following sample part number with corresponding additional informaton about JTS Series Bevel Gear Screw Jacks designs, configurations, end conditions, worm shaft codes and accessories. 


1. Models
JTS25, JTS50, JTS100, JTS150, JTS200
Note: click your required model web pages directly, there are specifications tables and assembly drawings for your reference.

2. Configuration and Designs
US = Upright Translating Screw Design;          IS = Inverted Translating Screw Design
UK = Upright Keyed Screw Design;                 IK = Inverted Keyed Screw Design
UR = Upright Rotating Screw Design;              IR = Inverted Rotating Screw Design
Note: The screw of a translating screw design jack must be attached to the load (guided) which prevents the screw from rotating. Add linear guides, rails or rolls are recommended.
Note: If your application involves a load which is unattached, unguided or the load is free to rotate and not translate, then a keyed screw design jack are required to prevent trapezoidal screw rotation (not recommended).


3. Travel Length
There are no standard travel length and all JTS series bevel gear screw jacks travel length are built with customers required.
Note: If compressive loads, must consider the trapezoidal screw permissible buckling load.


4. Gear Ratios
Each JTS series bevel gear screw jacks in two bevel gear ratios, H: high speed, L: slow speed

Models	H - High Ratio	Travel Length (mm),  Per Turn of Input Shaft	L - Slow Ratio	Travel Length (mm),  Per Turn of Input Shaft
JTS25	1:1	6	2:1	3
JTS50	1:1	7	2:1	3.5
JTS100	1:1	12	2:1	6
JTS150	1:1	12	2:1	6
JTS200	1:1	12	2:1	6

5. Screw End Conditions
Standard trapezoidal screw end conditions include I=top plate (fixing flange), II=clevis end (pivot bearing end), III=plain end, IV=threaded end, VI=fork end, VII=rod end, and no screw end with full threads lead screw.


6. Input Shaft Types
A: Single input shaft drive            
B: Inline double shafts drive          
B2: Right angle double shafts drive
C: Three shafts (T) drive            
D: Four shafts drive

Warning:
1. Input RPM should not exceed 1500 RPM.
2. Never exceed the JTS Series Bevel Gear Screw Jacks static and dynamic capacity.
3. Never exceed the power listed in our JTS Series Bevel Gear Screw Jacks specification tables. If the maximum power recommendation is exceeded, reduce the speed, use a larger capacity bevel gear screw jacks, choose another bevel gear screw jacks ratio, or consider a more efficient screw jack type such as a ball screw bevel gear screw jacks.
