ACL Race Series & CT-1 Calico Coating

ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world. When the hardened Tri-Metal construction of ACL Race bearings is combined with Calico's CT-1 Dry Film Lubricant coating, it creates the ultimate engine protection for high-RPM, high-stress motorsport applications.

CT-1 is a Dry Film Lubricant coating that helps reduce friction and abrasive wear. It provides intermittent dry lubrication and is not affected by dust or dirt. CT-1 is specifically engineered to withstand the extreme conditions of today’s high performance engines. Professional engine builders enjoy a higher level of confidence with increased embedability, strength and durability.

Process

CT-1 Dry Film Lubricant coating is applied as a spray process. Different surface preparation methods appropriate for the substrates will be used prior to the coating process.

Coating thickness is varied to suit the application. Typical coating thickness for engine bearings is 0.00025” to 0.00030” inch (6 to 7.5 microns).

Advantages

Provides intermittent dry lubrication, not affected by dust or dirt, low coefficient of friction. Thin coating to accommodate assembly constraints, chemical resistance, corrosion protection, reduced friction and drag resulting in decreased parasitic losses.

• Corrosion Protection
• Increased Lubricity
• Low Coefficient of Friction
• Oil and Fuel Resistant

Embedability

CT-1 coated bearings have excellent embedability characteristics, allowing debris contaminates to embed in the bearing, avoiding damage to the crank.

Extreme Oil Temperatures

CT-1 coated bearings have shown a reduction in oil temperatures as much as 8°C - 11°C / 15˚F - 20˚F. Lower oil temperatures also aid in the loss of viscosity due to extreme heat.

Low Oil Pressure / Oil Starvation

Theoretically a crankshaft rides on a thin film of oil that protects both the crank and bearing. Real world experience such as cold starts and rough terrain conditions have proven otherwise. CT-1 coated engine bearings provide a dry film lubricant that protects against intermediate oil starvation.
