A precision bearing is only as good as the lubricant protecting it. RSY Korea18 industrial lubrication range is engineered in direct complement to our bearings — for total machine protection.
A bearing running without the right lubricant isn't running — it's failing slowly. The film of oil or grease between rolling elements and raceways is the only thing preventing metal-to-metal contact. Get it wrong and even the most precisely engineered bearing will fail prematurely.
Temperature, speed, load, and environment all determine which lubricant is correct. RSY Korea18 lubrication range is engineered around those variables — not as an afterthought, but as an integrated part of the bearing system design.
The result: extended service intervals, lower operating temperatures, reduced noise, and bearing life that reaches — and exceeds — its calculated L10 rating.
Formulated for extreme thermal environments where standard greases fail. Maintains viscosity, film strength, and anti-wear performance from cold starts at −30°C through sustained operation at +220°C — without breakdown, separation, or carbonisation.
Engineered for efficient, reliable power transmission in high-pressure hydraulic systems. Outstanding oxidation stability, anti-wear protection, and demulsibility ensure pump and valve longevity even in demanding industrial cycles with frequent pressure surges.
Superior extreme-pressure protection for enclosed gear drives, worm gears, and open gearing across the heaviest industrial applications. The EP additive package creates a tough protective film under high contact pressure — preventing micropitting, scuffing, and gear tooth fatigue even under shock loading.
