Incorrect lubrication accounts for up to 36 % of premature bearing failures. All–purpose greases are inadequate for specialised bearing needs and can cause problems rather than be beneficial. bearing applications have wide variations of operating conditions and correct lubrication calls for matching the grease precisely to the application. bearing greases help ensure smooth, trouble–free operation and maximum reliability even under the most extreme conditions. They help prevent contamination from penetrating the bearing, cushion any shock loads and protect against corrosion.
