Case Study: Reduce Torque in Lead Screws
Application: Precision Motion Control Systems
Location: USA
Challenge
A medical component supplier came to us in search of a grease that would lubricate a lead screw found in several of their precision motion control systems for the Medical industry. This customer supplies components for a wide range of medical applications including ultrasound, neurostimulation, cardiac rhythm management, sensors, and more. When the proper lubricant is selected for lead screws, it can minimize friction, reduce torque, increase the system’s efficiency, and extend performance life.
- Can the lubricant reduce torque to extend the life cycle of the customer’s components?
Solution
UNIFLOR™ 8981
A PTFE thickened, heavy viscosity, completely fluorinated grease.
- Excellent high and low temperature performance
- Extends performance life
- Excellent thermo-oxidative stability
- Low vapor characteristics
| Product | Chemistry | Temp Range (°C) | Oil Separation (24 hrs @ 150°C) | Evaporation (24 hrs @ 150°C) |
|---|---|---|---|---|
UNIFLOR 8981 |
PFPE / PTFE | -65 to 250 | 8.7% | 0.18% |
Results
The medical component supplier compared UNIFLOR™ 8981 to competitor lubricants through a series of tests that evaluated life cycle, load carrying capacity, torque measurements, and current draw material compatibility. UNIFLOR™ 8981 outperformed all other lubricants and was chosen to lubricate the lead screws in their precision motor control systems.
