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.
Typical buyer situations
This topic usually appears in distributor stocking, repair replacement, machine retrofit, automation projects, and drawing-based purchasing. If a buyer sends only one model number, the supplier cannot judge the real use, packing risk, or whether machining upgrades are needed.
Details to confirm before quotation
To reduce repeated questions, the RFQ should cover product specification, use case, and delivery expectations together. The following points can be copied into the RFQ form or email.
- Purchase purpose: distributor stock, repair replacement, machine project, or sample testing.
- Specification: diameter, lead, overall length, thread length, nut type, and quantity.
- Machining: cut-to-length, end machining, and whether BK/BF, FK/FF, EK/EF, or other supports must be matched.
- Delivery: target quantity, expected lead time, packing, labels, shipping method, and whether shipment photos are required.
Common mistakes
A common mistake is asking only for unit price without application, quantity, or packing details. Another is sending photos without dimensions. This turns quotation into guesswork and can create errors in end machining, nut matching, or long-part shipping.
Next step
If the specification is clear, submit an RFQ directly. If the model or accuracy grade is still uncertain, describe the machine use and old part details so the supplier can recommend a standard part, bar stock, cut-to-length, or end machining route.
