...being turned during assembly, but are positioned or released by torqueing a nut. Screws are externally threaded fasteners that can be inserted into pretapped holes or can perforate a material and create their own internal threads. Screws are fastened...

Constant Force Springs

...springs that spin conversely at the same rate. The sum of the torques and opposing rotations offer stable extension at long deflections. Cavity mounting is an inexpensive mounting method, but does not feature a stop or brake. This high-friction design may...

...workpieces in relation to each other. Screws come in many varieties. The external threads on the screw can either mate with an internally threaded nut or hole, or cut its way into a soft material. Screws are inserted via torque applied--in a clockwise...
Technology | Test Equipment Depot | Newark. Calibration standards and reference sources provide standard values for calibrating instruments and comparing materials and components. Gage blocks, balls, and rings provide dimensional standards for calibration...

A malleable-metal lead shield allows machine screw anchors to compensate for uneven or irregular hole / roundness conditions. Screw anchors - Screw anchors (drop-in anchors) are used in concrete and solid block materials. Upon installation, four surfaces...

Load Cells

(380 companies)
Load cells are force sensors that often incorporate mechanical packaging to fit into testing and monitoring systems. They can be used for tension, compression, and/or shear measurement, and can be configured to measure force or load along one or more axes.

Combustion Engines

...often require warming up under very cold conditions before use. Diesel engines also provide more torque than gasoline engines. Liquefied propane gas (LPG) is a mixture of propane and butane which is a gas at standard conditions but can be stored...

Ball Valves

(2,066 companies) able to pass through the valve. When the valve is closed the ball is rotated so the hole is perpendicular to the flow, blocking the media. Segmented characterizable balls do not use the entire sphere to block flow; they only use enough to block...

Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits.

Butterfly Valves

(1,240 companies) Other seal arrangements use a clamp-ring and backing-ring on a serrated edge rubber ring to block extrusion of the O-ring. In high-performance designs, the seal maybe provided by an interference-fit seat design of a line-energizes seat design. The seal...
Bearing pullers and bearing tools are devices for assembling and disassembling bearings. They are often hand-held and manually-powered devices, but this area also includes mountable and powered devices like bearing heaters used before assembly.
Manifolds and manifold systems are fluid-distribution devices. They range from simple supply chambers with several outlets to multi-chambered flow control units including integral valves and interfaces to electronic networks.

Tapered Roller Bearings

...for moderate or high RPMs. The high-speed torque of a greased bearing is lower than an oiled bearing, but the opposite is true at lower speeds. Dry films are never an ideal lubricant, but are used where greases and oils may not be suitable. Films are difficult...

Boring Machines
