Single bearing, for single row bearing, roller bearing such simple design, is a separate type, suitable for high speed, and even very high speed, and very durable in operation, almost no maintenance.Such as single row angular contact ball bearings can only carry axial load in one direction.Such bearings under pure radial load, due to the rolling element load action line with radial load is not the same radial plane, produce internal axial force component, so must be installed in pairs.

In ultra small aperture in the miniature bearing, miniature deep groove ball bearing type has the metric 68 series, 69 series, 60 series, etc., inch on a total of 6 R series, based on this, also can be divided into with ZZ steel dust cover bearing series, rubber sealing ring with RS miniature bearing series, teflon bearings seals series and flanged penal series and so on.

Motor bearing and motor or motor bearing, bearing is specially applied to the motor or motor on a special bearings.Motor used in bearing is a supporting shaft parts, it can guide the axis of rotation, can also turn over the shaft parts, under the concept of bearing is very broad.Motor commonly used there are four types of bearing, the rolling bearing, sliding bearing, joint bearing and oil bearing.The most common type of motor bearing is rolling bearing, namely have a rolling element bearing.Sliding bearing to denote no rolling element bearings, the sliding movement of the bearing, which also some bearings for a Boundary Lubricants.

Rolling mill bearing, refers to the used for rolling industries, namely, non-ferrous metals, ferrous metals and non-metallic products rolling.Used for rolling roll diameter and the roll system of the roller bearings.Usually takes four row cylindrical roller bearing radial load, thrust roller or thrust ball bearing and radial angular contact ball or roller bearings carry axial load.Now most of the lubrication oil and gas or oil mist lubrication and grease lubrication cooling way.

Main Bearing is the direct holding support within the crankshaft Bearing.

General AISI52100 bearing steel (GCr15), stainless steel AISI440 cr18 (9), silicon nitride (Si3N4) and zirconia (ZrO2) four kinds of bearing material performance comparison, ceramic bearing as an important basis of mechanical parts, since it has the excellent properties of metal bearing can not reach, such as resistance to high temperature and super strength is leading the world in the new materials.For nearly 10 years, in the various fields of national economy and people's livelihood is becoming more and more widely used.

Use the plastic bearings in general can be divided into plastic rolling bearings and plastic sliding bearing;Plastic rolling bearing and the working principle of plastic sliding bearing can by name can distinguish, plastic rolling bearings rolling friction is the friction at work, and plastic sliding bearing work happens when sliding friction;The rolling friction is mainly depends on the size of the manufacturing accuracy;And the size of the plastic sliding bearing friction is mainly depends on the slip plane of the bearing material.

Spindle bearing performance, spindle imported bearing oil is a special lubricating oil for precision machine tools and similar equipment spindle bearing, it is to ensure the working accuracy and performance of the spindle, extending its service life plays a very important role, also known as bearing oil.

A set of bearings and made up by the above two kinds of bearing structure of rolling bearing.Such as needle roller and cylindrical roller bearings, thrust needle roller and thrust ball bearings, needle roller and angular contact ball bearings, etc.

For high speed and high power machines, a loss of lubricant can result in rapid bearing heating and damage due to friction. Also in dirty environments the oil can become contaminated with dust or debris that increases friction. In these applications, a fresh supply of lubricant can be continuously supplied to the bearing and all other contact surfaces, and the excess can be collected for filtration, cooling, and possibly reuse. Pressure oiling is commonly used in large and complex internal combustion engines in parts of the engine where directly splashed oil cannot reach, such as up into overhead valve assemblies.[21] High speed turbochargers also typically require a pressurized oil system to cool the bearings and keep them from burning up due to the heat from the turbine.

Some machines contain a pool of lubricant in the bottom, with gears partially immersed in the liquid, or crank rods that can swing down into the pool as the device operates. The spinning wheels fling oil into the air around them, while the crank rods slap at the surface of the oil, splashing it randomly on the interior surfaces of the engine. Some small internal combustion engines specifically contain special plastic flinger wheels which randomly scatter oil around the interior of the mechanism.

Bearings can be lubricated by a metal ring that rides loosely on the central rotating shaft of the bearing. The ring hangs down into a chamber containing lubricating oil. As the bearing rotates, viscous adhesion draws oil up the ring and onto the shaft, where the oil migrates into the bearing to lubricate it. Excess oil is flung off and collects in the pool again.

Some bearings use a thick grease for lubrication, which is pushed into the gaps between the bearing surfaces, also known as packing. The grease is held in place by a plastic, leather, or rubber gasket (also called a gland) that covers the inside and outside edges of the bearing race to keep the grease from escaping. Bearings may also be packed with other materials. Historically, the wheels on railroad cars used sleeve bearings packed with waste or loose scraps of cotton or wool fiber soaked in oil, then later used solid pads of cotton.

This example shows how to perform fault diagnosis of a rolling element bearing based on acceleration signals, especially in the presence of strong masking signals from other machine components. The example will demonstrate how to apply envelope spectrum analysis and spectral kurtosis to diagnose bearing faults and it is able to scale up to Big Data applications.

Joint bearing is a kind of spherical sliding bearing, the sliding contact surface is an inner spherical surface and an outer sphere, rotary oscillation motion can be in any Angle, it USES the surface phosphating, Fried, padded, spraying and other special craft processing method.Joint bearing with large load capacity, impact resistance, corrosion resistance, wear resistance, from the heart, good lubrication, etc.
