A double-tapped bushing, commonly shortened to bushing, is a fitting which serves as a reducer. It is a sleeve similar to a close nipple, but is threaded on both its inner and outer circumferences. Like a reducer, a double-tapped bushing has two threads of different sizes.
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
A drill bushing, also known as a jig bushing, [1] is a tool used in metalworking jigs to guide cutting tools, most commonly drill bits. Other tools that are commonly used in a drill bushing include counterbores, countersinks, and reamers. They are designed to guide, position, and support the cutting tool. [2]
IPSCO Inc. began as Prairie Pipe Manufacturing Co., Ltd. in Regina, Saskatchewan in 1956, changing its name to Interprovincial Steel and Pipe Corporation, Ltd. in 1960 and IPSCO, Inc. in 1984; [25] [26] the company would later be purchased by SSAB, and is the origin of SSAB's operations in the region. All SSAB operations in North America are ...
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.
The high-voltage primary windings are brought out to bushings on the top of the case. Single-phase transformers, generally used in the North American system, are attached to the overhead distribution wires with two different types of connections: Wye – A 'wye' or 'phase to neutral' transformer is used on a wye distribution circuit.
The term "bracket" refers to the tube fittings that are used to hold frame tubes together in lugged steel frames [1] which also form the shell that contains the spindle and bearings; the term is now used for all frames, bracketed or not. There is some disagreement as to whether the word axle or spindle should be used in particular contexts.
In electric power, a bushing is a hollow electrical insulator that allows an electrical conductor to pass safely through a conducting barrier such as the case of a transformer or circuit breaker without making electrical contact with it. Bushings are typically made from porcelain, though other insulating materials are also used.
