2005 vs 2010 Ball Screw: How to Choose?

Quick answer

2005 and 2010 share the same 20 mm diameter, but the lead is different. Choose 2005 for finer feed, higher thrust margin, or replacement of an original 5 mm lead screw; consider 2010 for faster travel and longer-stroke efficiency after checking motor torque, load, support span, and control settings.

Confirm diameter first, then lead

2005 and 2010 are both 20 mm diameter ball screws. The main difference is lead. 2005 favors higher thrust and finer feed, while 2010 favors faster linear motion and better long-travel efficiency.

Load and speed must be checked together

Buyers often judge diameter and lead separately, but selection should include motor torque, load, target speed, support span, and mounting direction. Otherwise the screw may be fast but weak, or strong but too slow.

Do not change lead casually for replacement

For machine repair, changing lead affects control parameters, speed ratio, and positioning result. Unless the system can be reset, 2005 and 2010 should not be swapped casually.

Confirm machine model and old screw marking.
Record diameter, lead, overall length, and nut style.
Describe load, speed, and horizontal or vertical mounting.
Confirm whether old-part end machining must be copied.

FAQ

**Can 2005 be replaced directly with 2010?**

Usually no. Changing lead from 5 mm to 10 mm changes speed ratio, thrust, motor load, and control parameters, so repair replacement should first confirm whether the system can be reset.
