13208 |
B |
| A detachable assembly in or on which a journal, gudgeon, pivot, or the like moves. It is used to carry a load and to reduce sliding friction. It does not employ rolling elements. The item consists of a bored precision ground ball (or spherical plain bearing) around which an outer ring is fitted. The assembly may be either separable or nonseparable. Excludes BEARING, PLAIN, ROD END and BEARING, PLAIN, SPHERICAL. | ||
BEARING, PLAIN, SPHERICAL |
13204 |
C |
| A detachable part in or on which a journal, gudgeon, pivot, or the like moves. It is used to carry a load and to reduce sliding friction. It does not employ rolling elements. It may be divided into two or more segments of 180 degrees (3.141 radians) or less. The item has a cylindrical bore and is basically spherical in its exterior design to allow for shaft misalignment. Excludes BEARING, PLAIN, SELF-ALIGNING. | ||
BEARING, PLAIN, TRACK ROLLER |
42389 |
J |
| A detachable assembly consisting of an outer and inner ring, designed for use in a track roller or similar application. It is used to carry a load and reduce sliding friction. It does not employ rolling elements, but may incorporate non-metallic liners or sleeves to aid in reducing friction and/or providing lubrication. See also BEARING, BALL, TRACK ROLLER and BEARING, ROLLER, TRACK ROLLER. Excludes BEARING, PLAIN, SPHERICAL and BEARING, PLAIN, SELF-ALIGNING. | ||
BEARING, SLEEVE |
13205 |
D |
| A tubular shaped item with or without flange(s) designed to reduce friction and carry a kinetic load on the surface(s) parallel to the axis of the bore. It must have a visible or detectable means of lubrication or be self-lubricated. The overall length must exceed 25 percent of the outside diameter or the shortest distance between peripheral flats of the body, except for straight tubular (without flange or shoulder) items having a bearing surface(s) parallel to the axis of the bore only. Includes items which are divided into 2 or more segments which include 180 degrees (3.141 radians) or less of the bearing periphery. See also BUSHING, SLEEVE; SPACER, SLEEVE; and WASHER (as modified). Excludes PIN, HOLLOW. | ||
BEARING, V |
20574 |
E |
| A cylindrical device, primarily designed to furnish a bearing surface for a low-speed oscillating shaft. The item consists of a precision machined or inclosed V or modified V groove and may include a drilled hole for spring loading. | ||
BEARING, WASHER, THRUST |
13211 |
L |
| An item of any peripheral shape usually having one flat or spherical surface and a centrally located hole. It is designed for applications involving moving (kinetic) loads. Except for items fabricated from bearing quality synthetic (plastic) or composed of multilayer material, one bearing surface must either have a specific surface finish designation of 32 microinch (0.8 micrometre) or less, arithmetical average (aa) (arithmetic mean deviation) or one of the following conditions: be lapped or ground; have visible or detectable means of lubrication; grooves, indentations; or self-lubrication. The thickness must not exceed 25 percent of the outside diameter of the shortest distance between peripheral flats (when thickness and/or outside diameter is designated as a tolerance dimension, the maximum dimension will be used to determine compliance). Excludes straight, tubular (without flange) items having a bearing surface(s) parallel to the axis of the bore only. See also WASHER, FLAT and SPACER, SLEEVE. | ||
Bushing |
||
| 1. A replaceable part, cylindrical in shape, hollow, and designed primarily to be inserted in a hole to reduce the effective inside diameter of the hole, and to protect the body structure about the hole from damage resulting from stress, strain, and vibration. Excludes BEARING, SLEEVE; GROMMET (as modified) and REDUCER (as modified). | ||
BUSHING BLANK |
21872 |
F |
| A solid metallic item, usually cylindrical, with or without a flange at one end. It is designed to be inserted into a hole to reduce the inside diameter of the hole and protect the surrounding body structure from damage resulting from stress, strain and/or vibration, but without a through hole parallel to the axis. It is intended for subsequent drilling operation. | ||
BUSHING, SLEEVE |
13206 |
K |
| A tubular shaped unthreaded item with or without a flange at one end designed to be inserted into a hole to reduce the inside diameter of the hole and to protect the surrounding body structure from damage resulting from stress, strain, and/or vibration. The overall length must exceed 25 percent of the outside diameter or the shortest distance between peripheral flats of the body. Includes items which are divided into two or more segments which includes 180 degrees (3.141 radians) or less of the bearing periphery. For items made of rubber, see BUSHING, NONMETALLIC. See also BEARING, SLEEVE; BUSHING, TAPERED; SPACER, SLEEVE; INSULATOR, BUSHING; and BUSHING, ELECTRICAL CONDUCTOR. Excludes BUSHING, DRILL, JIG. | ||

| A tubular shaped metallic item designed to provide a replaceable wearing surface for a centrifugal pump shaft. See also BEARING, SLEEVE; BUSHING, SLEEVE; and SPACER, SLEEVE. | ||
SPACER, SLEEVE |
13207 |
M |
| A tubular shaped item with a round or hexagon peripheral shape having two flat bearing surfaces perpendicular to the axis of the centrally located hole. It is designed to maintain a predetermined distance between assembled parts. The item may be with or without flange(s) of any peripheral shape. The overall length must exceed 25 percent of the outside diameter or distance across peripheral flats of the body. (When the length, outside diameter, and/or distance across peripheral flats are designed as a tolerance, the maximum dimension will be used to determine compliance). For items having other than a round or hexagon peripheral shape, see SPACER, PLATE. Excludes items with lubricating features, see BEARING, SLEEVE and BUSHING, SLEEVE. See also BUSHING, TAPERED; SPACER, RING; WASHER, FLAT; and WASHER, (as modified). | ||
