KDD Performance Bearing Coating Service

An Extra Layer of Protection When Conditions Are Anything but Normal

Under normal operating conditions, properly lubricated engine bearings experience very little wear and can provide an exceptionally long service life. Bearing failures typically occur because something else has gone wrong, such as oil starvation, contaminated oil, debris passing through the lubrication system, excessive heat, or a loss of oil pressure.

KDD's performance bearing coating service adds a durable, low-friction protective layer to the bearing surface. This coating provides an additional margin of protection during startup and other brief periods when the oil film may be compromised. It can also help the bearings tolerate heat, contamination, and momentary lubrication problems that could otherwise result in metal-to-metal contact and catastrophic engine damage.

In severe conditions, the coating acts as a sacrificial barrier between the bearing and the crankshaft. It cannot correct a failed lubrication system or replace proper maintenance, but it may provide enough protection to prevent crankshaft damage and save the engine when an unexpected problem occurs.

Benefits of Coated Engine Bearings

• Reduces friction during startup and momentary oil-film loss
• Provides added protection against oil starvation
• Improves resistance to heat, contamination, and debris
• Helps reduce bearing and crankshaft damage during abnormal conditions
• Adds valuable protection for high-performance, competition, towing, and severe-duty engines
• May help prevent a lubrication problem from becoming a complete engine failure

For an engine built to deliver greater performance, reliability, and durability, coated bearings are affordable insurance against the conditions that cause most bearing failures.
