The SCE24 needle roller bearing is a high-performance, thin-walled drawn cup bearing engineered for applications where space is limited and radial load requirements are high. Featuring a precision-steeled outer ring and hardened needle rollers, the SCE24 (also known as B24 or BA24) offers a low cross-section and maximum power density.
