Caterpillar 4F-2041 Cup Bearing Caterpillar 4F-2041

4F-2041 Cup Bearing, Caterpillar Cat, is the cup Half of a tapered roller bearing assembly designed for Cat equipment. This cup-only component features a 190.50 mm outer diameter and is intended to pair with a compatible cone bearing to form a complete tapered roller bearing set. Cup bearings like 4F-2041 are engineered to withstand large radial and thrust loads while reducing friction between mating parts in drivetrain or hitch interfaces. Caterpillar emphasizes that Cat bearings are built to application-specific standards to ensure drive-train components wear as a coordinated system, helping minimize downtime when used with the matching cone. This part for Cat machines carries a California Prop 65 warning due to potential lead-containing materials. The 4F-2041 designation identifies the cup portion of the tapered roller bearing pair, enabling technicians to source the corresponding cone for a full installation. Note that this is the cup component only; the inner cone and rolling elements are not included and must be sourced separately.
