AXIS Hangzhou EPG Co.,Ltd. , was founded in November, 1997. With its 5 wholly owned subsidiaries.ISO 9001:2000 & AS 9100B certified custom manufacturer of roller chain & sprockets. Specifications of roller chain & sprockets include 0.1475 in. to 0.3750 in. pitch, 5.9 in. to 35.4 in. length, 180 lbs. to 1529 lbs.10sile load capacity & 0.035 lbs. to 0.276 lbs. w8/ft.Brand 1621-ZZ ball bearing is manufactured with precision, performance, and longevity in mind. specifically, size 1621-ZZ bearing utilizes the shielded design for keeping the premium Mobil Polyrex EM grease in, while keeping contents out, the benefit of this is longer performance and bearing protection. What sets AXIS brand deep groove 1621-ZZ bearings apart from others is the utilization of grade-10 balls, a high-strength steel retainer, being made to ABEC 3 precision standards, finely h1d raceways, premium Exxon Mobil Polyrex EM grease, and noise and vibration chain & sprocket testing at the factory on each bearing to ensure consistent quality. For more information or to get a quote on ABEC 3, precision AXIS 1621-ZZ shielded ball bearings please contact us and we will be happy to assist you.

AXIS 1621-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 RetainerSteel 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 1ABEC 3 tolerances provide superior precision, efficiency, and greater speed capabilities.Finley H1d Raceways vs. Non-H1dThis reduces friction and vibration which results in longer bearing life and better performance.Exxon Mobil Polyrex EM GreaseThe highest quality bearing grease on the market, Exxon engineers have put in countless hours and chain & sprocket 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 TestingTesting 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 QualityElectric motor quality, also known as EMQ for short is an industry designation for a higher precision, higher quality bearing than the standard.
