Lubrication reduces friction and prevents temperature rise in gears. Three main methods: grease, splash (oil bath), and forced oil circulation. Method choice depends on tangential and rotating speeds
Water-resistant greases up to +60°C for Archimedian screws. Non-water-resistant greases up to +120°C for water pumps. Multipurpose greases up to +120°C for various applications. High-temperature greases (>+120°C) for heavy loads
Mineral oils are basic, affordable but perform poorly. Semi-synthetic oils combine mineral and synthetic for better protection. Synthetic oils provide highest performance but are most expensive
ISO VG classifies industrial lubricants based on viscosity at 40°C. ISO VG 22-100 grades provide different properties for various applications. ISO VG 32-100 are suitable for hydraulic systems and high-stress applications
ACEA was founded in 1991 by 15 major European car manufacturers. ACEA sets oil standards but doesn't approve them. New standards are updated every few years to reflect industry developments
