Question 5

What is an Annular Ball Bearing?

Accepted Answer

An Annular Ball Bearing (BEARING,BALL,ANNULAR) is a cylindrical device in which the inner or outer ring turns upon a single or double row of hardened balls which roll easily between the two rings, thus minimizing friction. For items with faces specially ground for duplex mounting see BEARING, BALL, DUPLEX. Excludes BEARING, BALL, AIRFRAME.

Question 6

What is a Cylindrical Roller Bearing?

Accepted Answer

A Cylindrical Roller Bearing (BEARING,ROLLER,CYLINDRICAL) is a nonadjustable roller bearing consisting of a single or multiple-row of hardened cylindrical rollers and a retainer used with or without inner or oute r rings. Excludes BEARING, ROLLER, AIRFRAME.

Question 7

What is a Self-Aligning Roller Bearing?

Accepted Answer

A Self-Aligning Roller Bearing (BEARING,ROLLER,SELF-ALIGNING) is an antifriction bearing having a cylindrical rolling element and one spherical raceway which will adjust to varying degrees of shaft and/or support misalignment without damage to the raceways and permits the full rating of the bearing to be utilized.

Question 8

What is a Journal Roller Bearing?

Accepted Answer

A Journal Roller Bearing (BEARING,ROLLER,JOURNAL) is an item in which the shaft or revolving part turns upon hardened rollers usually contained in a cage. It must contain an inner or outer race, or both. For items without a race(s), see RETAINER AND ROLLER, BEARING.

Question 9

What is a Thrust Ball Bearing?

Accepted Answer

A Thrust Ball Bearing (BEARING,BALL,THRUST) is an antifriction bearing having a ball rolling element, designed to resist axial thrust, or to support an axial load. Excludes BEARING, BALL, PIVOT.

Question 10

What is a Tapered Roller Bearing?

Accepted Answer

A Tapered Roller Bearing (BEARING,ROLLER,TAPERED) is a cylindrical device in which the inner cone or outer cup turns upon a single or double row of tapered hardened rollers which roll easily in a race, thus minimizing friction and designed to carry a radial load and capable of sustaining axial thrust. Excludes BEARING, ROLLER, THRUST.

Question 11

What is a Tapered Roller Bearing Cone And Rollers?

Accepted Answer

A Tapered Roller Bearing Cone And Rollers (CONE AND ROLLERS,TAPERED ROLLER BEARING) is an assembled inner component of a tapered roller bearing, consisting of a cone (which provides a contact surface for the rolling elements of the bearing), a complement of tapered rollers (the rolling elements), and frequently a retainer (which spaces the rolling elements).

Question 12

What is a Bearing Ball Retainer?

Accepted Answer

A Bearing Ball Retainer (RETAINER,BALL,BEARING) is a frame or inclosure which spaces and retains the rolling elements of a BEARING, BALL (as modified).

Question 13

What is a Bearing Ball?

Accepted Answer

A Bearing Ball (BALL,BEARING) is a homogenous spherical body, a series of which provides the rolling elements in a BEARING, BALL (as modified). The item is designed primarily to alleviate friction. It may have other usages such as the checking component in a ball-type check valve. Excludes BALL, CHECK; BALL, VALVE, PORTED.

Question 14

What is a Bearing Roller?

Accepted Answer

A Bearing Roller (ROLLER,BEARING) is a cylindrical body of either solid or hollow construction which provides the rolling elements in the roller bearing.

Question 15

What is a Needle Roller Bearing?

Accepted Answer

A Needle Roller Bearing (BEARING,ROLLER,NEEDLE) is a single or multiple-row antifriction bearing used with or without inner or outer races characterized by relatively small size rollers usually not ranging above 0.250 inch (6.35mm) diameter and generally longer in length in relation to diameter.

Question 16

What is a Bearing Retaining Plate?

Accepted Answer

A Bearing Retaining Plate (PLATE,RETAINING,BEARING) is a comparatively flat rigid item, with or without a centrally located aperture, designed to hold an annular bearing or a sleeve bearing in a fitted inclosure. It must have drilled and/or tapped holes for mounting purposes. Excludes END BELL, ELECTRICAL ROTATING EQUIPMENT.

Question 17

What is a Mechanical Equipment Bearing Replacement Parts Kit?

Accepted Answer

A Mechanical Equipment Bearing Replacement Parts Kit (PARTS KIT,BEARING REPLACEMENT,MECHANICAL EQUIPMENT) is a parts kit consisting of one or more bearings or bearing assemblies, which are issued as a unit for repair/replacement. It may include gasket(s), O-ring(s), race(s), seal(s), spacer(s), washer(s), or the like.
