High-temperature lithium complex or polyurea grease with EP additives, replenished every 2,000-5,000 operating hours depending on load and environment.
Proper bearing selection reduces friction losses by 15-30%, improves heat dissipation, and prevents premature wear, directly impacting motor lifespan and energy consumption.
Increased noise (grinding/clicking), elevated temperature (>70°C above ambient), irregular vibration patterns, and visible wear particles in lubricant.
