Description of HK1616 Drawn Cup Needle Bearing used as Auto Spare Parts 1.Overview: Drawn cup needle roller bearings ,needle roller bearing support radial loads and reduce friction between rotating components, with a drawn outer shell serving as a raceway for the rollers. The low cross section of the drawn cup bearing provides high load-carrying capability with minimum required space. Drawn cup bearings are easily installed with a press fit in the housing.   2.Advantages:needle roller bearing - Smaller cross-section leading to greated rigidity,higher load-carrying capacity & lower inertia of the needle roller bearings help size and weight reductions in machinery. - Though they are less wide,their load carrying capacity is high and is most suitable for applications where the load is high & the radial space is less. - Needle roller bearings,which are designed to withstand oscillation can operate under severe conditions & interchange with sliding bearings   3.Applications:needle roller bearing - Transmissions,transfer cases,engines & valve trains -Steering and braking systems - Axle support -Outboard engines   3.Expanded Options - Assemblies with bearings - Engineered polymer cages - Bearings with one or two seals -Closed end bearings - Oil holes -Drawn sleeve   4.Needle roller bearing specifications & Standards: -Dimensions:the boundary dimensions of the drawn cup needle roller bearings are in accordance with ISO -Bore size:Its size is meassured in millimeters.The bore is a hollow cylindrical chamber or barrel shaped where the metal balls  are placed. -Outer ring width:It is the width of the outer ring measured in millimeters.   5.Markets: needle roller bearing or needle bearing for Transmissions, transfer cases, engines, valve trains, steering and braking systems, axle supports,outboard engines, power tools, copiers, fax machines, paper-moving equipment and appliances.   Parameter of HK1616 Drawn Cup Needle Bearing used as Auto Spare Parts
