The early linear motion bearing method; that is, a row of wooden poles placed under the raft. This skill may be traced back to the time of construction of the Great Pyramid of Giza; although there is no clear basis. Modern linear motion bearings use one. Kind of operation principle; only sometimes use a ball instead of a roller.
The earliest sliding and tumbler bearings were made of wood. Ceramics, sapphires or glass were also used; steel, copper, other metals, plastics (such as nylon, bakelite, Teflon and UHMWPE) were used.
From heavy-duty wheel axles and machine tool spindles to fine wall clock parts; rotary bearings are required in many applications. The simplest rotary bearing is a bushing bearing; it is only a bushing sandwiched between the wheel and the axle. This depiction is subsequently Roller bearings are replaced; many cylindrical rollers are used instead of the original bushings; each roll is like a single wheel. The earliest useful roll bearing with cage is the waller John 0?? 760 years created for the manufacture of H3 chronographs.
An ancient Roman ship found in Lake Nami, Italy; an example of an early ball bearing was discovered. This wooden ball bearing was used to support a rotating tabletop. This ship was built in 40 BC. I heard that Leon Nado 0? Moved? 500 years ago, a ball bearing was previously depicted. Among the various immature elements of ball bearings; it is very important that there will be bumps between the balls; the formation of rated conflicts. But this can be avoided by putting the ball in a small cage. The 17th century; Galileo made the earliest depiction of the "fixed ball"; perhaps the "cage ball" ball bearing. But then for a long time later The bearing on the machine has never been completed. The first patent on the ball channel was obtained by Carmarthen's Philippe 0?? in 794.
