Tools
Use load calculation, allowable speed calculation, self-locking judgment, and tolerance fit lookup to match application requirements and shorten evaluation cycles.
Match models by diameter, lead, load, accuracy, and related parameters for engineering follow-up.
Enter nominal diameter, lead, ball diameter, circuits, rows, and effective stroke to calculate basic static load Co and dynamic load Ca per specification.
Enter nominal diameter, ball diameter, support span, root diameter, support configuration, and screw type to calculate critical speed limit N1 and DN value limit N2.
Enter pitch diameter, lead, thread angle, and material pair to compute helix angle and judge self-locking under dry and lubricated conditions.
Enter basic dimension and hole/shaft tolerance bands per GB/T 1800.1—2020 to look up limit deviations and analyze clearance, transition, or interference fits.
FAQ
Engineer FAQs on product support, installation, maintenance, and selection
Quick guidance:
Note: Higher accuracy grades cost more to manufacture—select to actual requirements and avoid over-specification.
Common causes and remedies:
If issues persist, submit a technical ticket via Contact Us.
Recommended lubrication intervals:
Recommended greases:
Preload selection principles:
Note: Higher preload increases friction torque and temperature. Use the minimum preload that meets positioning requirements to maximize life.
