Railway Bearing My email :skfbearing@chinakmbearing.com whatsapp:008618678825008     KMY BEARING provides tapered roller bearing units and compact tapered roller bearing units for various rail transit vehicles.     The products have been widely used in freight wagons including heacy wagons,subways and light rails. Consist of two inner rings, one common outer ring, two tapered roller and polymer cage assemblies, a central spacer, grease fill and two sealing systems.    Further components like lateral spacers, backing rings and end caps with their locking device can be added to the assembly as well as components based on specific customer requests.    roller bearing units were designed to replace plain bearings. These inch size TBU designs had to match the existing relatively long journal dimension. This design enables the integration of a seal wear ring on both sides where the garter seals are riding.     AAR has standardized these garter seals and seal wear rings, which are interchangeable with components from different bearing manufacturers. offers special LL seal designs for inch size TBUs that generate much lower friction.    LL seal benefits • improved protection against contaminants • longer grease life • better and longer performance Polymer spacer benefits: • fretting corrosion avoided • lower wear rate of the inner ring side face/backing ring contact zone • longer performance and longer maintenance intervals achievable because of longer grease life.      Grease life (and consequently TBU maintenance intervals) can be increased by providing a relubrication in service:     An amount of fresh grease is pumped into the unit and mixed with the already used grease    In this way it is possible to respect the most demanding maintenance intervals leader in the friction management and power transmission industries and continues to lead in advancing bearing technology through continuous innovation and development. In addition to railroad applications, AP bearings are successfully used in many types of industrial applications. This can be attributed to many factors including the bearing’s high load carrying capacity and its adaptability to a wide variety of applications. advantages of  HM127442(90930) Tapered Roller Train Railway Bearings • Self-contained unit provides substantial cost savings in design and installation. Many mounting parts are available with the bearing assembly. • Pregreased unit reduces installation costs. • Preassembled bearing reduces the number of separate parts to be applied and helps reduce the chance of incorrect assembly. • High quality, tested and improved radial lip seals provide exceptional protection, minimum relubrication and low maintenance. • Positive alignment of rollers is maintained in the bearing due to its basic tapered roller construction. This distributes the load over the entire roller length and helps to prevent rollers from skewing. • On-apex design provides true rolling motion with less friction and more resistance to wear. • Case-hardened and hardened cones, cups and rollers put hardness where it is needed at the working surfaces. The core of these parts, being more ductile, resists the propagation of fatigue cracks and spalls. 2 - HM120848 cones;1 - HM120817XD cup;1 - HM120848XA cone spacer (fitted for normal internal clearance);2 - K86890 seal wear rings ;2 - K86895 seal assemblies;1 - K86874-90010 backing ring assembly consisting of: 1 - K86874 backing ring ;1 - K89716 vent fitting
