Product Description

Product Description
needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The ends of the rollers are relieved slightly to modify the line contact between the rollers and raceways. This prevents stress peaks at the roller ends to extend bearing service life. In spite of their low cross section, needle roller bearings have a high load carrying capacity. Therefore, they are extremely suitable for bearing arrangements where radial space is limited.
C&H supplies needle roller bearings in many different designs, series and in a wide range of sizes, which make them appropriate for a wide variety of operating conditions and applications.
