What is the function of a bearing?
Friction is bound to occur between the rotating shaft and the part that supports the rotation. Bearings are used between these two components. The bearings serve to reduce friction and allow for smoother rotation. This cuts down on the amount of energy consumption.

What does C4 mean on a bearing?
C3 – Refers to a “greater than standard clearance”. This is the most common type of bearing, and is the correct choice for the majority of applications. C4 – Refers to “greater than C3 clearance”. Not as common as C3, but often specified in small engine crankshaft bearings.
What is a bearing clearance?
Bearing internal clearance is defined as the total distance either inner or outer ring can be moved when the other ring is fixed. If movement is in the radial direction, it is called radial internal clearance; if in the axial direction, axial internal clearance.
How do you read a bearing number?
The first digit indicates the width or height series (dimensions B, T or H). The second digit identifies the diameter series (dimension D). The last two digits of the basic designation identify the size code of the bearing bore. The size code multiplied by 5 gives the bore diameter (d) in mm.
What is bearing characteristic number?
Bearing characteristic number = N. p. μ It is a non-dimensional number, where µ is the viscosity, N is the speed of the.
What is meant by bearing modulus?
Bearing modulus is a modulus used in journal bearing design. It is a dimensionless number. ==Formula== Bearing Modulus (C) is C = (Zn/p) where For any given bearing, there is a value for indicated by C, for which the coefficient of friction is at a minimum.
What are hydrodynamic bearings?
HYDRODYNAMIC THRUST BEARINGS These bearings are made of either metal or high strength ceramic and designed specifically for demanding applications with high loads. Lubricant is distributed through grooves in the bearing to form a lubricant layer which prevents metal to metal contact.
What is meant by hydrodynamic lubrication?
Hydrodynamic lubrication occurs when non-parallel rigid bearing surfaces lubricated by a film-fluid slide over each other, forming a converging wedge of fluid and forming a lifting pressure (Williams, 1994).
What type of lubrication is best for the engine?
The most popular lubes are usually moly-based (Molybdenum Disulfide) and are designed to operate at high temperatures. Newer compounds are manufactured with additives that hold up better under extreme pressures and also act as rust inhibitors much like the compound Cosmoline.
What are the types of lubrication?
There are 4 types of lubricants: Oil, Grease, Penetrating Lubricants, and Dry Lubricants. The 2 most common lubricants you’ll be dealing with daily are oil and grease, however, your facility will still be using dry and penetrating lubricants.
What is mixed lubrication?
Mixed lubrication is an operating state (regime) of a lubricated contact in which surface roughness ( Surface Roughness) significantly affects the performance of the contact. It may occur with conformal contact lubrication, such as journal bearing lubrication.
What is extreme pressure lubrication?
Extreme pressure additives, or EP additives, are additives for lubricants with a role to decrease wear of the parts of the gears exposed to very high pressures. They are also added to cutting fluids for machining of metals. The chemical reaction between the additives and the surface is confined to this area.
Which one of the following is incorrect for boundary lubrication?
Question 9: Which one of the following is INCORRECT for boundary lubrication? A. Solid surfaces are so close together that appreciable contact between opposing asperities occurs and lubricants become ineffective.
What is lubrication and types?
There are three different types of lubrication: boundary, mixed and full film. Each type is different, but they all rely on a lubricant and the additives within the oils to protect against wear. Elastohydrodynamic lubrication is similar but occurs when the surfaces are in a rolling motion (relative to each other).
What are the characteristics of a good lubricant?
A good lubricant generally possesses the following characteristics:
- A high boiling point and low freezing point (in order to stay liquid within a wide range of temperature)
- A high viscosity index.
- Thermal stability.
- Hydraulic stability.
- Demulsibility.
- Corrosion prevention.
- A high resistance to oxidation.
What is the purpose of using lubricant?
Functions of lubrication : To lubricate each part of the bearing, and to reduce friction and wear. To carry away heat generated inside bearing due to friction and other causes. To cover rolling contact surface with the proper oil film in order to prolong bearing fatigue life.
