However, now, bigger versions of the heavy-duty tire changers are designed to mount/demount tires up to 95 inches (2.4 m) in diameter and also feature a hydraulically operated self-centering four-jaw chuck with clamping jaws that can clamp from 14 to 58 inches (0.36 to 1.47 m) either from the wheel’s inside or from the center bore.

For years, HP Vacuflo advocated the slightly smaller 1 + 13 ⁄ 16-inch (4.6 cm) piping size (outside diameter), claiming that their studies showed that it was less likely to clog. However, that manufacturer has also switched to the de facto industry standard size of 2-inch (5.1 cm) outside diameter piping and corresponding fittings. In most ...
Jeep Cherokee with 2 in (51 mm) suspension lift on 31 in (790 mm) diameter BFG all-terrain tires, using add-a-leaf and coil spring spacers The Jeep CJ vehicles had leaf spring suspension on both axles, which rendered the lifting process relatively simple. In this case, an inherent disadvantage of extreme lifting becomes obvious – the owner ...
Slotted spring pin (1) and washer (2) used to secure a shaft (3). A spring pin (also called tension pin or roll pin) is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the diameter of the hole they are intended for, and a chamfer on ...
These same 8 washers can be arranged in a 3-3-2 configuration (=), a 4-4 configuration (=), a 2-2-2-2 configuration (=), and various other configurations. The number of unique ways to stack n {\displaystyle {n}} washers is defined by the integer partition function p ( n ) and increases rapidly with large n {\displaystyle {n}} , allowing fine ...
A flat spring fixed only at one end like a cantilever, while the free-hanging end takes the load. Coil spring Also known as a helical spring. A spring (made by winding a wire around a cylinder) is of two types: Tension or extension springs are designed to become longer under load. Their turns (loops) are normally touching in the unloaded ...
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
Rings are also sprung to increase the contact force and to maintain a close seal. The spring force is provided by either the stiffness of the ring itself or by a separate spring behind the seal ring. It is important that rings float freely in their grooves within the piston, so that they can stay in contact with the cylinder. [5]
