China Needle Roller Bearing

China Needle Roller Bearing

Needle bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity, and lower inertia forces that facilitate size and weight reductions in machinery. They're designed to withstand oscillation, perform under severe conditions, and interchange with sliding bearings. Diverse types of needle bearings are available in a wide variety of sizes and tolerances, for a multitude of applications.

Product Details

The diameter ratio of the needle bearing and the length of the roller of the roller bearing are between 0.1 and 0.4. The typical structure consists of a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race (sometimes the housing itself). The friction coefficient of the rolling bearing is only 0.001-0.005.

Its radial structure is compact, its inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, and it is especially suitable for the support results of limited radial mounting dimensions. However, such bearings can only withstand radial loads.
