Choosing Bearing Grease: What Grease for Car Bearings

Why It Matters

Grease reduces friction, dissipates heat, seals and prevents rust. Wrong grease kills bearings early.

Types

• Lithium: General purpose, most suspension bearings
• Complex lithium: High temp, water resistant - hub bearings
• Synthetic: Wide temperature range, long life
• Moly grease: Heavy load, low speed

Selection

• Temperature: Match dropping point to service temp
• Speed: Lower consistency for high speed
• Sealed: Maintenance-free bearings need no regreasing
• Compatibility: Mixing types causes separation

Fill Amount

Fill 1/3-1/2 of internal space - overfilling causes heat. Huami tip: quality seals keep grease in.
