Introduction
This Grind the ball screw employs high-accuracy grinding technology, achieving accuracy class C3 (±0.008mm/300mm stroke) with transmission efficiency ≥90%. Ideal for high-precision positioning, high rigidity, and long-life applications in automated equipment. ISO 9001 certified, supporting customized designs (e.g., special leads, nut types, protection levels).
product highlights
1. High-Precision Grinding Technology
Grind the ball screw Processed by CNC grinding machines with lead error ≤±0.005mm/300mm (C3 class), repeat positioning accuracy ±0.003mm.
Case: A semiconductor wafer handling equipment using C3 screws achieved positioning accuracy of ±1μm.
2. High Rigidity & Long Service Life
Ball screw shaft hardness HRC58-62, nut with Gothic arch groove design, dynamic load capacity increased by 30%.
Life test: Continuous operation at 10m/min for 10,000 hours without abnormal wear.
3. Low Friction & Quiet Design
Friction coefficient ≤0.002, driving torque only 1/3 of sliding screws.
Internal circulation structure with noise-reducing return pipes, operating noise ≤65dB.
4. Diverse Customization
Nominal diameter: 16mm-100mm
Lead: 5mm-50mm

Application Scenarios
-
Installation Requirements
Parallelism of mounting surface ≤0.02mm/m, parallelism between screw and guide rail ≤0.03mm/m.
Avoid striking the screw shaft; use special tools during installation. -
Lubrication & Maintenance
Inject appropriate grease (recommended NSK LG2) before initial operation.
Check lubrication status every 2,000 hours or 6 months, replenish or replace grease promptly -
Environmental Conditions
Operating temperature: -20℃ to +80℃ (customizable for special conditions).
Avoid corrosive gases and dusty environments; recommend installing protective covers -
Load and operational limitations
Avoid operating beyond the rated dynamic and static loads to prevent premature wear or damage of the balls and raceways.

FAQ
Q:Is it normal to make a slight sound when running?
A:A slight and even sound is generally fine. However, if the sound suddenly becomes louder or there are abnormal sounds like "clunk" or "friction", it might be due to insufficient lubrication, impurities, or the installation being a bit crooked. At this point, it's best to stop and check.
Q:How often is it better to add grease? What will happen if I forget to add it?
A:It is generally 2,000 hours or added once every six months (whichever comes first). If you forget to add it, the friction between the lead screw and the nut will increase, which may cause overheating and jamming. In severe cases, it may wear out the parts. It's better to remember a time to remind yourself.
