Are Shock Loads Permissible on a Screw Jack ?
Shock loads should be eliminated or reduced to a minimum, if they cannot be avoided, the screw jack model selected should be rated at twice the required static load. For severe shock load applications, using the E-Series, S-Series, and M-series screw jacks, the load bearings should be replaced with heat-treated steel thrust rings which is an option available from Power Jacks. Note this will increase the input torque by approximately 100 percent.
