Needle roller bearings are roller bearings, which have high load carrying capacity with a very small section height They are available with or without an inner ring In all needle roller bearings, except for full complement needle roller bearings, the needle rollers themselves are guided parallel to the axis by a dimensionally stable cage Needle roller and cage assemblies are offered in single/double row, solid/split cage, metric and inch sizes, as well as connecting rod bearings for special applications Features: Smaller cross-section, higher load carrying capacity, greater rigidity and lower inertia forces that facilitate size and weight reductions in machinery 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 tolerance for a multitude of applications Bore sizes: 3 to 1,500mm Outside diameters: 5 to 2,000mm Precision rating: P0/P2/P3/P4/P5/P6, non-standard, EMQ level.
