Order Code for Acme Screw Jack
(1) Model and (4) Gear Ratio
* Acme screw jack models: JT-0.5T, JT-1T, JT-2T, JT-3T, JT-5T, JT-10T, JT-15T, JT-20T, JT-30T, JT-40T, JT-50T, JT-100T.
* All models are withstand the maximum static load capacity, not dynamic load capacity. The dynamic loads depends on Stroke, Lifting Speed, Working Conditions etc. About the safety dynamic load capacity, please consult JACTON sales engineers.
* If long stroke acme screw jack with compression loads, please calculate maximum critical buckling force. Please consult JACTON sales engineers.
* Acme screw jack has self locking, no need brake motor or locking device. Vibration loads must be avoided, otherwise, self-locking function will be failure.
* Each Acme screw jack with three gear ratios as standard. Custom-made others bigger gear ratios, please consult JACTON sales engineers. * Please check corresponding models technical parameter table.
(2) Jack Configurations and Jack Designs
* US: Upright mount, Translating Screw Design. * IS: Inverted mount, Translating Screw Design.
* UR: Upright mount, Rotating Screw Design. * IR: Inverted mount, Rotating Screw Design.
* UK: Upright mount, Anti-rotation Screw Design. * IK: Inverted mount, Anti-rotation Screw Design.* Important Note: The lifting screw of a translating screw jack must be attached to the guided load which prevents the lifting screw from rotating. To add the linear guides, rails or rolls are recommended.* Important Note: If your application involves a load which is unattached, unguided or the load is free to rotate and not translate, then an anti-rotation keyed screw jack(key and keyway) are required to prevent lifting screw rotation (not recommended).
* Important Note: Single lead with self-locking, Double lead with higher speed, but may lower under load. Brake motors or external locking devices are recommended. * Available in Double Clevis Acme Screw Jack, and Trunnion Mounting Acme Screw Jack (pivoting load).(3) Stroke and (5) Screw End Fittings* Stroke is travel expressed in millimeter(mm) or inches and not the actual screw length.* Standard Screw End Fittings: top plate(load pad), clevis end(male clevis), plain end, threaded end. Also rod end, and fork head(female clevis) are available. Custom screw ends are acceptable.(6) Input Shaft Codes and Optional Shaft Codes
