Self-lubricating plain bearings category and classification

Bearing belongs to the category “general equipment manufacturing industry”, “bearings, gears, transmission and drive components manufacturing” in the class, “bearing manufacturing” small classes, is loaded axle parts, referred to as “mechanical joint”, is the basis of the indispensable in modern machinery and equipment parts.Bearing main function is to support the axis of rotation, or other movement of the body, rotating or moving during movement and the transfer of the load on the shaft or shaft parts, as long as it is movement joints where there is a bearing.Bearing can be divided into two categories, rolling bearing and sliding bearing.Work happens when rolling friction rolling bearings, sliding bearings work, it’s happened between surface and surface sliding friction;These are two different forms of exercise;Rolling bearing materials and manufacturing technology at home and abroad are already very mature, and the sliding bearing materials and manufacturing technology with the constant improvement of the design and use requirements are also gradually innovation development.Sliding bearing is the function of a support shaft operation with the bearing spaced out protect the shaft and bearing seat, an important function is to reduce the friction coefficient and wear;Sliding bearing according to the material and performance can be divided into self-lubricating sliding bearing and sliding bearing commonly, self-lubricating sliding bearing in the process of work can not achieve refueling refueling or less, and general sliding bearing itself does not have good lubrication function so must refueling operation process;Self-lubricating sliding bearings in general can be divided into three categories:
1, oil bearing, including porous metal, wood and oil bearing high polymer material;Such as feit oilless bearing the FU series of bearings.
2, dry friction bearing, its itself is not oily, the working process of the no oil or other fluid lubricant.It includes some of the plastic, metal and inorganic materials for matrix composite materials of bearing;Such as feit SF – 1, SF – 2, bearing JDB – 1.
3, special bearing, including rubber bearings, air bearings and magnetic bearings.Such as FD – AL bearing.
