General Specifications

All references for lead screws in DINGS have following characteristics.

Lead Screw Material
303 Stainless precision cold rolled steel
Screw Coating
Teflon coating is optional
Standard Screw Accuracy
0.0071 inch/foot (0.18mm/300mm)
Screw Straightness
0.08 inch/foot (6.66mm/Meter), measured as Total Indicated Runout (TIR). All screws are carefully checked for straighness before shipment.
Screw Efficiency
From 35% to 85% dependent on lead. Also depends on the usage of an Anti-Backlash nut with screw. The larger lead, higher efficiency of screw.
Operating Temperature
-20°C to +50°C
Storage Temperature
-20°C to +50°C, Keep in dry.
Screw Backlash
0.01mm~0.1mm, depends on different lead. Anti-Backlash nut should be considered for high bi-directional positioning repeatability.
System Backlash
Includes screw, motor and attached mechanics. This will be the sum of all backlash in customer's motion axes.
Nut Material
Polyacetal or Polybutylene with lubricating additive. Standard is a free-whelling nut (Anti-backlash nut is available)
Wear Life of Screw and Nut
Depends on load, speed, duty cycle and environmental factors but typically it is ≥ 5 Million cycles.
Special Note
DINGS' Linear systems are manufactured from high quality materials. Because of variable effects of friction, lubrication and cleanliness, exact life cycle can not be predicted.
