This is the maximum load experienced by the bearing spread over its projected area. For this the engine builder will need to know peak cylinder pressures and balance these forces with the inertial load (acceleration of piston and conrod masses). Generally speaking ACL Race bearing materials and design allow a great deal of flexibility for upgrading engine performance having an excellent balance of strength and forgiveness. The trade-off is: high load = shorter life. ACL Race bearings work well in street machines, that are rarely used at max power but are expected to have a normal engine life, as well as in 'Top Fuel' Dragster engines where bearing loads are several hundred MPa but life is measured in seconds!\u003c\/p\u003e\n\u003ch3\u003eCeramic Coating\u003c\/h3\u003e\n\u003cp\u003eDo you want lowered friction and more galling protection from your bearings? Then our advanced dry film lubricant ceramic coating is what you need. This coating will not need any changes to clearances as it bonds at 20 millionths of an inch or can be buffed to a \"0\" tolerance while still retaining it's properties. This coating will greatly reduce power robbing friction and actively retain oil films even after sitting for months or being oil starved in high-g racing to minimize the chances of a galled bearing.

This is the maximum load experienced by the bearing spread over its projected area. For this the engine builder will need to know peak cylinder pressures and balance these forces with the inertial load (acceleration of piston and conrod masses). Generally speaking ACL Race bearing materials and design allow a great deal of flexibility for upgrading engine performance having an excellent balance of strength and forgiveness. The trade-off is: high load = shorter life. ACL Race bearings work well in street machines, that are rarely used at max power but are expected to have a normal engine life, as well as in 'Top Fuel' Dragster engines where bearing loads are several hundred MPa but life is measured in seconds!\u003c\/p\u003e\n\u003ceol\u003e\n\u003ch3\u003eCeramic Coating\u003c\/h3\u003e\n\u003ceol\u003e \u003ceol\u003e\n\u003cp\u003eDo you want lowered friction and more galling protection from your bearings?
