2. Bead roller - Wikipedia

   en.wikipedia.org/wiki/Bead_roller

   A bead roller is a machine tool that makes rigid lines in sheet metal to make surfaces more rugged and durable. The lines bead rollers add to sheet metal prevent warping and disfigurement by adding structural integrity to the metal.

3. Tube beading - Wikipedia

   en.wikipedia.org/wiki/Tube_beading

   Tube beading is a metal forming process that forms a bead on the end of a tube. Tube beads can be used to help hold a hose on the end of a tube or to strengthen the end of the tube. [ 1 ] There are two forming processes: internal roll forming and ram forming .

4. Tube bending - Wikipedia

   en.wikipedia.org/wiki/Tube_bending

   The tube is held in tension by a wiper die to prevent any creasing during stress. A wiper die is usually made of a softer alloy such as aluminum or brass to avoid scratching or damaging the material being bent. Much of the tooling is made of hardened steel or tool steel to maintain and prolong the tool's life.

5. Roller burnishing - Wikipedia

   en.wikipedia.org/wiki/Roller_burnishing

   The tooling is pressed into the surface of the part while it is rotated (in some applications, the tools are rotated instead of the part). The burnishing tool rolls against the surface of the part at a constant speed, producing a very consistent finish across the part. A surface finish of less than Ra 0.1 μm is achievable with roller ...

6. Tube (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Tube_(fluid_conveyance)

   Both pipe and tube imply a level of rigidity and permanence, whereas a hose is usually portable and flexible. A tube and pipe may be specified by standard pipe size designations, e.g., nominal pipe size, or by nominal outside or inside diameter and/or wall thickness. The actual dimensions of pipe are usually not the nominal dimensions: A 1-inch ...

7. Spherical roller bearing - Wikipedia

   en.wikipedia.org/wiki/Spherical_roller_bearing

   Spherical roller bearing with a brass cage in a cut-through view A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring.
