Lubrication in hydraulic systems reduces seal friction and wear. Hydraulic fluid itself acts as a lubricant, but dry running during startup can damage seals. Pre-lubrication with compatible grease prevents initial wear. In food-grade systems, food-safe lubricants are mandatory. Insufficient lubrication causes heat buildup, hardening, and cracking of seals, especially in high-speed app... https://globalsealstech.com/hydraulic-seals/
