What is the difference between 220 and 320 gear oil?
1 Answers
The difference between 220 and 320 gear oil lies in their kinematic viscosity: the kinematic viscosity of 220 gear oil ranges from 198 to 242, while that of 320 gear oil ranges from 288 to 352. Gear oil primarily serves to lubricate gears and bearings, prevent wear and rust, and assist in heat dissipation for gears. Both 220 and 320 gear oils refer to medium-load gear oil CKC, representing medium extreme pressure gear oil, commonly used in the gearboxes, reducers, turbines, and gearboxes of machinery and equipment. The characteristics of this series of lubricants include good load-carrying capacity and anti-scuffing properties, excellent thermal and oxidation stability, good adhesion, and they are free of solvents, asphalt, heavy metals, and chlorine, meeting environmental requirements.
