  • Needle roller cam follower for higher mileage applications of light, medium and heavy duty vehicles
    Patent number: 8991351
    Abstract: A roller assembly for a diesel engine used in a high mileage vehicle includes a roller having an exterior roller surface and an interior surface that defines a bore extending therethrough. A pin is positioned in the bore and defines an exterior pin surface. A plurality of rolling elements is positioned between the exterior pin surface and the roller interior surface. Each of the rolling elements rollingly engages the exterior pin surface and the roller interior surface. The roller assembly defines a clearance of between about 0.01 mm to about 0.03 mm between the rolling elements, the exterior pin surface and the interior surface. The roller assembly is configured to achieve extended life criteria wherein the clearance does not increase to more than 0.02 mm to 0.06 mm after 500,000 miles of travel of a vehicle powered by a diesel engine having the roller assembly installed therein.
