Performance
Guide - Torque to move nut:

(Frictional & acceleration torque as well as frictional resistance of bearings of sub assemblies need to be taken into account).
Tensile Strength (Rm): <Ø16 (ØD): 520-700N/mm² >Ø16 (ØD): 600-950N/mm²
Yield Stress (Re): <Ø16 (ØD): 320-380N/mm² >Ø16 (ØD): 430N/mm²

Other Info.
Lengths: 1000mm supplied as standard. 2000mm (price x 2) and 3000mm (price x 3)
For power transmission and continuous use, always use bronze nuts, never steel.
Nuts and screws should always be lubricated with grease or oil.
Steel nuts should be used with steel screws for hand motion only.
Thread rolled Trapezoidals in steel toughened (still machinable).
To be used with our range of nuts : 2 Start Leadscrews available.
