Specialty Greases for Precision Motion Systems
Engineered lubrication solutions for linear guides, ball screws, automation equipment and precision machinery.
Choose grease based on the actual operating condition — speed, load, stroke, temperature, contamination sensitivity and motion profile.
Choose by Operating Requirement
Different motion conditions require different lubrication performance.
Low Friction
Reduce sliding resistance in high-speed and long-stroke motion.
Heavy Load & EP
Designed for applications requiring strong extreme-pressure and mechanical stability.
Fretting Resistance
For short-stroke, oscillating and micro-motion applications.
Low Dust
For clean and contamination-sensitive environments.
Stable Rolling Resistance
For low-speed, micro-stroke applications requiring stable motion resistance.
High Speed & Low Heat
For high-speed ball screw and motion systems where heat generation must be controlled.
Wide Speed Range
For applications operating from low speed to high speed.
Water Resistance
For environments with moisture exposure or coolant washdown.

Need help selecting a grease?
Send us your operating conditions and current lubricant.
Select by Motion Component
Find grease according to the component you are lubricating.
Note: Final grease selection should consider load, speed, stroke, temperature, environment and compatibility with the existing lubricant.
Which Grease Fits Your Application?
A professional engineering selection process.
What are you lubricating?
Main operating challenge?
Operating Conditions
- • Speed (m/min or rpm)
- • Load (N)
- • Stroke length
- • Temperature (°C)
- • Environment
Product recommendations are for preliminary selection. Application validation is recommended before replacing an existing lubricant.
Technical Data That Supports Product Selection
Compare physical and tribological properties before beginning application validation.
Test methods and available data vary by product.
One Grease Cannot Fit Every Motion System
Precision engineering requires precision tribology.
High-Speed Systems
May require lower base-oil viscosity and lower resistance to prevent overheating and energy loss.
Heavy-Load Systems
Require stronger extreme-pressure (EP) performance and mechanical stability to maintain the lubricating film.
Short-Stroke Motion
Can easily create fretting wear due to restricted lubricant replenishment. Specialized additives are needed.
Clean Environments
Cleanroom equipment requires stricter dust and contamination control, demanding low-dust grease formulations.
