Question 1

The rolling elements will ride in what is referred to as a ____.&#10;A) drum&#10;C) race&#10;B) cylinder&#10;D) ringer

Accepted Answer

The rolling elements in a bearing ride in a groove or channel called a "race." Option A (drum) and B (cylinder) are not typically used to describe the part of a bearing that the rolling elements ride in. Option D (ringer) is not a term commonly used in reference to bearings.

Question 2

What type of bearing load is present when pressure from the load is parallel to the axis of the shaft?&#10;A) radial&#10;C) thrust&#10;B) axial&#10;D) radial-axial

Accepted Answer

When pressure from the load is parallel to the axis of the shaft, it is an axial load. Therefore, option B - axial, is the correct choice.

Question 3

The ____ roll between the inner and outer rings.&#10;A) races&#10;C) separators&#10;B) rolling elements&#10;D) lubricators

Accepted Answer

The rolling elements, such as balls or rollers, are the components of a bearing that roll between the inner and outer rings. The races guide the rolling elements, the separators keep the rolling elements evenly spaced, and the lubricators provide lubrication for smooth operation.

Question 4

What type of bearing load is present when the pressure from the load is perpendicular to the axis of the shaft?&#10;A) radial&#10;C) thrust&#10;B) axial&#10;D) radial-axial

Accepted Answer

Radial load occurs when the force is perpendicular to the axis of the shaft, causing the bearing to support weight or pressure from the sides.

Question 5

Which series of bearing is used for a light-duty application?&#10;A) Series 100&#10;C) Series 300&#10;B) Series 200&#10;D) Series 400

Accepted Answer

Series 200 bearings are typically used for light-duty applications, while Series 100 bearings are used for medium-duty applications, Series 300 bearings for heavy-duty applications, and Series 400 bearings for extra heavy-duty applications.

Question 6

____ is a bonding, shearing, and tearing away of material from two contacting or sliding metals.&#10;A) Spalling&#10;C) Stripping&#10;B) Galling&#10;D) Gouging

Accepted Answer

Galling is the process of material transfer and adhesion from one metal surface to another during sliding contact, which can result in bonding, shearing, and tearing. Spalling occurs when surface material fractures and flakes away, stripping refers to complete removal of a coating or layer, and gouging involves mechanical damage caused by a hard object scraping against a surface.

Question 7

What type of bearing load is present when pressure from the load is both perpendicular and parallel to the axis of the shaft at the same time?&#10;A) radial&#10;C) thrust&#10;B) axial&#10;D) radial-axial

Accepted Answer

When the pressure from the load is both perpendicular and parallel to the axis of the shaft at the same time, it creates a combination of radial and axial load. Therefore, the best choice would be radial-axial load.

Question 8

Which of the following is not a type of Babbitt metal?&#10;A) steel&#10;C) bronze&#10;B) aluminum&#10;D) copper-lead

Accepted Answer

Steel is not a type of Babbitt metal. Babbitt metals are usually made up of tin, copper, and antimony, and may also contain other metals such as lead or silver. Common Babbitt metals include copper-lead, tin-based, and aluminum-based alloys.

Question 9

Which of the following has a cup and a cone?&#10;A) ball-thrust bearing&#10;C) taper-roller bearing&#10;B) angular-contact bearing&#10;D) stave bearing liner

Accepted Answer

A taper-roller bearing has both a cup and a cone. The cup is basically the outer ring while the cone is the inner ring of the bearing. This design allows the bearing to withstand both radial and axial loads.

Question 10

A ____ bearing is usually a sleeve or bushing that may support radial and axial loads.&#10;A) standard&#10;C) roller&#10;B) plain&#10;D) ball

Accepted Answer

Plain bearings, also known as sleeve bearings, rely on a surface of sliding contact to support a load. They can handle both radial and axial loads and are often used in applications where low speed or intermittent operations are required. Roller and ball bearings, on the other hand, are designed for high-speed applications and are better suited to handle primarily radial loads. Standard bearing is a general term that refers to bearings that meet industry standards and can include both plain and rolling bearings.

Question 11

Before most roller bearings can be installed onto a shaft, they first must be ____.&#10;A) lubricated&#10;C) tested&#10;B) painted&#10;D) heated

Accepted Answer

The answer of Before most roller bearings can be installed...

Question 12

____ damage occurs when continual impacting forces (such as vibrations) are passed from one ring to the other, through the rolling elements, when there is no rotation of the shaft.&#10;A) External&#10;C) Spalling&#10;B) False Brinell&#10;D) Excessive

Accepted Answer

The answer of ____ damage occurs when continual impacting forces...

Question 13
