See “High Speed Operation” and “Operation in Presence of Dust, Water or Corrosive Vapors” above. GREASE LUBRICATION. DODGE Type C Bearings are prepacked with a NLGI #2 lithium complex grease. For relubrication select a grease that is compatible with #2 lithium complex. The Timken Company TIMKEN BEARING DAMAGE ANALSIS WITH LUBRICATION REFERENCE GUIDE 7 Types of Bearing Damage Many different operating conditions can cause bearing damage. Those listed in this section make up the most commonly identified causes of damage for anti-friction bearings, including cylindrical, spherical, tapered and ball designs. Types of Lubrication. Five forms of lubrication can be identified: 1. Hydrodynamic 2. Hydrostatic 3. Elastohydrodynamic 4. Boundary 5. Solid film  Hydrodynamic (or full-film): in this type, the surfaces of the bearing are separated by a relatively thick film of lubricant (to prevent metal to metal contact).

Five Rights of Lubrication •Right Type of Lubricant •Right Quality •Right Amount •Right Place •Right Time. Causes of Friction in a Bearing A At Rest B Starting Up C Steady Speed t Smooth Rough Surfaces Hydrodynamic 0 Lubrication Velocity Lubrication and Friction. Full-pack solid grease is standard for self-aligning ball bearings, spherical roller bearings, and needle roller bearings. Primary advantages: (1) Grease leakage is minimal. (2) Low bearing torque with spot-pack type solid grease For more details, please refer to NTN special catalog of Solid grease bearings. The Timken Company TIMKEN BEARING DAMAGE ANALSIS WITH LUBRICATION REFERENCE GUIDE 7 Types of Bearing Damage Many different operating conditions can cause bearing damage. Those listed in this section make up the most commonly identified causes of damage for anti-friction bearings, including cylindrical, spherical, tapered and ball designs. The bearings with which we are concerned fit two basic categories – ball and roller. We will discuss both categories, and cover bearing types, installation, operating conditions, maintenance and troubleshooting. In addition, we will feature one particular type – the tapered roller bearing – . See “High Speed Operation” and “Operation in Presence of Dust, Water or Corrosive Vapors” above. GREASE LUBRICATION.

This publication gives a comprehensive overview of the lubrication .. surfaces and the kinematics of certain bearing types, such as axial. physical properties of the lubricant, notably the dynamic viscosity, that dictate coefficient dependent on materials and rolling-element bearing type (Table 19). 3. Being a solid when not under shear, grease forms an effective collar at bearing edges to help seal against dirt and water. 4. With grease lubrication, leakage is. bearing maintenance and lubrication, therefore NTN- .. This grease is for long- term lubrication for any type of bearing subjected to extreme temperatures. Lubrication of Bearings. In a bearing, lubrication forms a thin oil film on both the rolling surface and sliding surface to prevent metal- to-metal contact. White Paper on bearing lubrication including the role of bearing lubricant, types of lubricants, lubrication methods, shelf life Download PDF of this information. bearings. The maintenance of a sufficient lubrication oil film ensures stable and continuous . Table 1 Free space of open type deep groove ball bearing. REGIMES OF FLUID FILM LUBRICATION AT THE RIB-ROLLER CONTACT of the bearing types developed to combat these problems are discussed in (45). Was the bearing correctly lubricated with the right lubricant and did the lubricant meet proper specifications for the service? • Were the seals the right type. The purpose of bearing lubrication is to prevent direct for rolling bearings, lubrication has the following . V: Quantity of bearing space open type (approx.) .
