What is the replacement interval for industrial closed gear oil 320?

First, confirm whether the industrial closed gear oil 320 is fully synthetic. Fully synthetic gear oil is SHC320, while mineral oil is XP600220. For mineral oil, the replacement interval is 5,000 hours. For fully synthetic oil, under normal operating conditions, the replacement interval exceeds 10,000 hours. The exact replacement time should be determined based on regular inspections. Advantages of industrial gear oil: Excellent load-carrying capacity, suitable for gear systems operating under harsh conditions; outstanding lubrication performance, far superior to traditional mineral-based gear oils, extending component lifespan. Precautions for industrial gear oil: Industrial gear oil cannot replace automotive engine oil, as their lubrication properties and viscosity differ, which may affect the engine.

I previously used this type of oil when maintaining equipment in a chemical plant. The replacement cycle for industrial closed gear oil ISO 320 definitely can't be generalized. For equipment running 24/7 non-stop, we conducted oil analysis every six months and replaced immediately if viscosity changes or contaminant levels exceeded standards. For regular production line equipment with light loads and clean environments, mineral oil could last about two years. The key factors are: the manufacturer's recommended interval in the manual, whether the oil color has turned black, and if operating temperature exceeds 90°C. I remember that time when the centrifuge gearbox overheated - the oil thickened like asphalt after just eight months of use. Fortunately, timely detection prevented a major accident.

The lab just completed a gear oil lifespan test. For 320 viscosity oil, the key factor is the base oil formulation. Mineral oil can last up to two years in a clean, room-temperature environment at best, while full synthetic oil starts at five years. But let's face it, workshops are never ideal environments. In dusty workshops, particles contaminating the oil can wear out gears in just three months. In humid conditions, water ingress causes oil emulsification, requiring replacement in as little as half a month. For normal operating conditions, we recommend setting the initial replacement interval at one and a half years, followed by quarterly sampling to monitor three key indicators: replace if viscosity change exceeds 15%, replace if acid value increases by 1.5 mgKOH/g, and replace if iron content surges significantly indicating gear wear.

Having repaired mining machinery for twelve years, I've found that 320 gear oil has an exceptionally short lifespan in crushers. Under heavy-duty operation during summer with continuous running, the oil temperature can soar to 110°C, causing the oil to oxidize and turn black within three months. In contrast, mineral oil in lightly loaded conveyor belt gearboxes can last two years. The telltale signs of gear oil's end of life are a burnt smell and a gritty, non-slippery feel when rubbed between fingers. Once saw a factory that hadn't changed oil for three years - the gear meshing surfaces were completely scored, and replacing that gearbox cost enough to buy ten years' worth of oil. When checking oil levels monthly, take a glance at the sight glass too; if the oil turns coffee-colored, start preparing for an oil change.
