Starting Torque is 0% greater than torque shown. For loads less than 25% of rated loads add tare drag torque. 3) Maximum allowable horsepower ratings are based on a 35% duty cycle. For operation at higher duty cycles or repeated use over any segment of the total travel, temperature must be monitored and remain less than 95 C. 4) Overload capacity of the Metric ball Screw Jack is as follows: 0% for dynamic loads, % for static loads. 5) All Ball Screw Jacks can backdrive and require some means of holding the load, such as a brake on the motor. The product specification pages show holding torque values. Holding torque represents the amount of input torque required to restrain the load and does not indicate recommended brake size to bring dynamic load to stop. 6) All units are suitable for intermittent operation providing that the housing temperature including ambient is not lower than - C. or higher than +95 C. Factory supplied grease in standard units will operate in this range.

METRIC BA COUMN STRENGTH: METRIC BA WORM GEAR Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity. If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the ball screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength. The chart below is used to determine the required jack size in applications where the lift shaft is loaded in compression. To use this chart: Find a point at which the maximum length intersects the maximum load. Be sure the jack selected is above and to the right of that point. CAUTION: chart does not include a design factor. The chart assumes proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw. Consult Nook Industries, Inc. if side thrust is anticipated, operating horizontally, or maximum raise is greater than times the screw diameter.

Jacks can be matched to within ±.05mm per 0mm when ordered as matched sets. Special ground threads having lead accuracies of.013mm per 0mm can be provided if necessary. BACKASH Axial backlash ranges from.2 to.5 mm. Specify optional selective fit lift shaft for 0.13 to 0.2mm backlash. MATERIA HARDNESS Ball screws have a race hardness of Rockwell C 58 minimum. Core hardness will run from Rc to 35. NOTES: Refer to ubrication Instructions in order to obtain maximum life from ball screw assemblies These values may be greatly reduced if the units are subjected to misalignment, shock loads, side thrust, contamination or lack of proper lubrication and maintenance.

Consult Nook Industries, Inc. if side thrust is anticipated, operating horizontally, or maximum raise is greater than times the screw diameter. oad (kn) 1,000 A B C D 700 0 0 0 0 70 7 5 3 2 1 0 1 0 EM EM EM5 EM2.5 EM1 EM05 0 1 0 0 0 4 0 0 2 0 7 1,000 3 700 1,0 1,0 0 1,000 1,0 2,000 1,000 2,000 3,000 4,000 1,0 3,000 4,0 6,000 2,0 5,000 7,0,000 MOUNTING CONDITIONS A ONE END FIXED ONE END FREE B BOTH ENDS SUPPORTED BY CEVIS ENDS C ONE END FIXED, ONE END SUPPORTED (CEVIS ATTACHED TO GUIDE STRUCTURE) ONE END FIXED, ONE END SUPPORTED (RADIA BEARING)) D BOTH ENDS FIXED (TOP PATE ATTACHED TO GUIDED STRUCTURE) METRIC TRAPEZOIDA TECHNICA DATA (mm) Metric Trapezoidal Screw Jacks AVAIABE IFT SCREW ENGTHS As a major manufacturer of industrial lead screws, Nook Industries stocks a broad selection of trapezoidal screws.
