Selecting the best grease for wheel bearings
- Improper lubrication is a major cause of bearing failure. Insufficient lubrication, degraded grease and use of the wrong lubricant account for 36% of all bearing failures.
- Every precaution should be taken to prevent premature bearing failure, so selecting the correct grease is essential for reliable operation.
What is bearing grease?
SKF considers lubricant essential to the proper operation of any bearing system. Grease can be described as “thickened oil”. Bearing grease is generally made from base oil held in a thickener with various additives. Changing these components produces greases for different applications. Grease is commonly a soap mixture emulsified with mineral or vegetable oil. It is primarily a lubricant with a semi-solid structure that can flow like a liquid under stress. Its most important functions are corrosion inhibition and lubrication. When choosing a grease, always consider base-oil viscosity, consistency, thickener and intended application.
Grease for wheel bearings
Grease is used in systems that could be oil-lubricated but where oil would not remain in place. It also acts as a seal against water ingress. Its consistency provides excellent frictional performance in bearings. Avoid assuming that a general-purpose grease suits every mechanism; the wrong choice can do more harm than good. Bearings operate under diverse conditions, so the lubricant must match the application. SKF offers a special wheel-bearing grease with extreme-pressure performance and thermal stability throughout its operating range, including intermittent operation up to 220°C (428°F), making it suitable for wheel bearings.
Benefits:
- Excellent short-term lubrication at temperatures up to 220°C (428°F)
- Protects wheel bearings operating under harsh conditions
- Effective lubrication in wet conditions
- Good water and corrosion resistance
- Excellent lubrication under heavy loads and at low speeds
How to grease wheel bearings
Do wheel bearings need grease? SKF offers guidance on the correct procedure. Distribute grease evenly through the free space between the rolling elements and bearing rings. Rotate the bearing by hand until all internal surfaces are covered. For larger bearings, such as truck wheel bearings, SKF offers bearing-grease packs. Correct application ensures even grease distribution among the rolling elements, cage and raceways.
