7 nti-acklash for Screw Jacks The nti-acklash feature provides a reliable method to regulate the axial backlash in a screw jack for applications where there is a reversal of loading from tension to compression. The amount of backlash between the screw and worm gear nut can be adjusted (adjust shell cap) to a desired amount or a practical minimum. To avoid binding and excessive wear do not adjust backlash to less than 0.025mm. nti-acklash ear djustable Shell ap The nti-acklash feature also acts as a safety device, providing dual nut load carrying unit, when the worm gear becomes worn. It can also be fitted with a wear indicator for critical applications. This can be further upgraded to use a sensor for automatic detection (consult Power Jacks). The S-Series nti-acklash screw jacks are available with an inverted screw design for maximum design flexibility (refer to diagram on the left).

8 nti-rotation (Keyed) for Screw Jacks The nti-rotation feature for translating screw jacks stops the lead screw from rotating without the need for end pinning. This is done by keying the lead screw. However the keyway in the screw will cause greater than normal wear on the internal threads of the worm gear. imensions for nti-rotation The dimensions for these screw jacks are the same as the standard units except those detailed below.

9 nti-rotation with nti-acklash or Safety Nut The anti-rotation feature can be combined with the nti-acklash or Safety Nut mechanism into one screw jack. or this option the anti-rotation device is located in-line with the cover pipe. s with the standard anti-backlash screw jack these are also available with an inverted screw design for maximum design flexibility (refer to diagram below). imensions for nti-acklash with nti-rotation (Keyed) The dimensions for these screw jacks are the same as the standard anti-backlash units except those detailed below.

10 with Safety Nut kn Power Jacks metric machine screw jacks can be fitted with a safety nut, which provides 2 safety roles: kn kn 1. In the event of excessive wear on the nut thread the load will be transferred from the standard nut to the safety nut. This will also provide visual wear indication as the gap between the safety nut decreases to zero as the standard lifting nut wears. 2. In the unlikely event of catastrophic nut thread failure the safety nut will sustain the load. The safety of industrial and human cargo is therefore improved. There are several configurations for each safety nut device as they only work in one load direction. or this reason when ordering please supply a sketch of your application showing load directions.
