AXIS 1620-ZZ Ball Bearing Benefits
Grade-10 Balls vs. Grade-25Grade 10 balls, normally found in ABEC 5 (or better), instead of grade 25. The grade 10 balls have tighter tolerances (+/- 0.05 micrometers versus +/- 100 micrometers). This ensures a rounder, more precise diameter ball and gives a longer life because the balls share the load evenly.
Steel Retainer vs. Glass Filled Nylon Retainer
Steel retainers out-last and outperform nylon retainers that are typically found on other bearings within the same class. Steel retainers especially out-perform Nylon in high-temp applications.
ABEC 3 Precision vs. ABEC 1
ABEC 3 tolerances provide superior precision, efficiency, and greater speed capabilities.
Finley Honed Raceways vs. Non-Honed
This reduces friction and vibration which results in longer bearing life and better performance.
Exxon Mobil Polyrex EM Grease
The highest quality bearing grease on the market, Exxon engineers have put in countless hours and testing to come up with the new standard for premium bearing grease. All AXIS ball bearings come pre-supplied with this grease versus a lower-quality grease found in standard bearings.
Individual Noise and Vibration Testing
Testing both the noise and vibration levels on each and every ball bearing before packing ensure that the quality and consistency will be on par with the quality expected from AXIS bearings.
Electric Motor Quality
Electric motor quality, also known as EMQ for short is an industry designation for a higher precision, higher quality bearing than the standard.
