    Heavy Duty Needle Roller Bearings (Machined)重载滚针轴承(机加工)

    201312922541555906 Machined Type Heavy Duty Needle Roller Bearings are bearings with a low sectional height and large load ratings.机加工型重载滚针轴承是一种截面高度低,负荷额定值大的轴承。 The outer ring has high rigidity and can easily be used even for light alloy housings.外圈具有高刚性,即使轻合金外壳也可轻松使用。 These bearings are available in metric series and inch series, both of which have the caged type and the full complement type.这些轴承有公制系列和英制系列,均有笼式和满装式。 It is therefore possible to select a suitable bearing for use under various conditions such as heavy loads and high-speed or low-speed rotations.因此可以在各种条件下选择合适的轴承,例如重载和高速或低速旋转。 In addition, there are bearings with and without an inner ring.此外,还有带有和没有内圈的轴承。 As the type without inner ring uses a shaft as the raceway surface, a compact design is possible.由于没有内圈的类型使用轴作为滚道表面,所以可以实现紧凑的设计。

    Design Attributes设计属性

    High-strength cage retains and guides rollers高强度保持架和导向滚轮
    High speed and lubrication-retention capability.高速和润滑保持能力。 A lubrication groove and hole in the OD facilitate relubrication through the outer ring.外径上的润滑槽和孔有助于通过外圈再润滑。
    Bearings can be used with or without a machined and ground inner ring depending on the suitability of the shaft as a raceway surface.根据轴作为滚道表面的适用性,轴承可以带或不带机加工和磨削的内圈。
