The R1810 model is engineered for reliability in extremely damp and high-humidity environments, utilizing genuine SUS304 stainless steel. Its structural design enhances dust and moisture sealing, preventing condensation from penetrating the internal raceways.
Bearing Features
In terms of chemical stability, the 304 material effectively resists corrosion caused by airborne chloride ions. Consequently, the R1810 ensures consistently smooth rotation—without seizing due to salt-laden air—in applications such as outdoor surveillance PTZ units, marine interior equipment, and automatic curtain motors. Additionally, its low-friction cage design reduces energy consumption, thereby extending the battery life of powered devices.
