Product introduction
The Cummins 2882087 bearing features a double-row angular contact ball bearing design with integrated high-temperature NBR seals, optimized to withstand rotational loads up to 5,200 rpm and extreme thermal cycling environments. As an original equipment manufacturer (OEM) part for 6.7 Cummins engine bearings and 5.9 Cummins engine bearings, the 2882087 engine bearing is specifically optimized for the cooling systems of ISB series 5.9L and 6.7L engines, ensuring a perfect match with the fan hub, pulley, and crankshaft. It adopts a double-sided contact seal to achieve completely closed operation, eliminating the need for regular greasing or maintenance, thus reducing operating costs and the risk of human error.

Product Advantages
The Cummins 2882087 bearing is a double-row angular contact ball bearing that can simultaneously withstand combined radial and axial loads under high-speed rotation, meeting Cummins' "1 million miles" durability standard and significantly improving operational stability under heavy load, high temperature, and high vibration conditions. The bearing steel is heat-treated for strength, and the seals are temperature resistant up to +150°C, providing long-term protection against coolant leakage, dust intrusion, and alternating thermal shocks, ensuring continuous and reliable operation in high-temperature and high-humidity regions such as Chongqing.
