2. Roller locked - Wikipedia

   en.wikipedia.org/wiki/Roller_locked

   The ball-bearing roller locking system used in straight-pull rifles like the Anschütz 1827 Fortner, Crossfire MK1, Heym SR 30 and Savage Impulse. The collet locking system used in the Blaser R8 / R93 / Blaser Tactical and Thompson .30-06 prototype which uses an expanding collet in a similar fashion.

3. Shaft collar - Wikipedia

   en.wikipedia.org/wiki/Shaft_collar

   His safety set collar was soon copied by others and became an industry standard. The invention of the safety set collar was the beginning of the recessed-socket screw industry. [1] Set screw collars are best used when the material of the shaft is softer than the set screw. Unfortunately, the set screw causes damage to the shaft – a flare-up ...

With the new design came a new dry-fire method; instead of the ...

7. Rolling-element bearing - Wikipedia

   en.wikipedia.org/wiki/Rolling-element_bearing

   The downsides to this bearing is that due to manufacturing complexities, tapered roller bearings are usually more expensive than ball bearings; and additionally under heavy loads the tapered roller is like a wedge and bearing loads tend to try to eject the roller; the force from the collar which keeps the roller in the bearing adds to bearing ...

8. Horse harness - Wikipedia

   en.wikipedia.org/wiki/Horse_harness

   A horse harness is a device that connects a horse to a horse-drawn vehicle or another type of load to pull. There are two main designs of horse harness: (1) the breast collar or breaststrap, and (2) the full collar or collar-and-hames. For pulling heavy loads, a full collar is required because it distributes pressure over a larger area of the ...

   For example, a widely used ball bearing slide in the furniture industry is a ball bearing drawer slide. Commonly constructed from materials such as aluminum, hardened cold rolled steel and galvanized steel , ball bearing slides consist of two linear rows of ball bearings contained by four rods and located on differing sides of the base, which ...
