K 240X250X42

The K 240X250X42 is a radial needle roller and cage assembly, representing a highly compact and efficient bearing unit. This specific design consists of a single row of needle rollers held and guided within a precision-engineered cage. Unlike conventional bearings, it does not have inner or outer rings. Instead, it is designed to run directly on a hardened and ground shaft and within a similarly prepared housing bore, which serve as the raceways. This construction results in a bearing arrangement with an exceptionally small radial cross-section, making it an ideal choice for applications where space is severely restricted. The dimensions 240x250x42 refer to its inner diameter, outer diameter, and width, respectively.

The primary advantage of the K 240X250X42 assembly is its remarkable radial load-carrying capacity relative to its minimal size. By utilizing the machine components as raceways, it allows for the design of very stiff and accurate bearing arrangements without the bulk of traditional bearings. This leads to lighter, more compact, and more cost-effective machinery designs, particularly in applications like planetary gear sets, automotive transmissions, and industrial pumps. The precise guidance of the rollers by the cage ensures excellent speed capabilities and reliable performance, offering engineers a high-performance solution for creating robust systems within a minimal footprint.
