(hereinafter referred to as NSK) has successfully developed high-speed ball bearings for electric vehicle drive motors. The development of the product can greatly improve the speed of the driving motor, which has made a great contribution to reducing the energy consumption of electric cars, extending the range of driving and improving the comfort of driving. NSK expects the product to reach a sales target of 10 billion yen by 2030.

Bearing ring is a one or a few raceway centripetal roller bearing ring parts.

Flange bearing from printers, fax machines to monitor, in the household goods used in daily life has a flange bearing products show the space of technology.In the size and accuracy requirement of the standard ABEC - level 1, the production of bearings, can satisfy the general use of products.

Axial bearing roller bearing thrust bearing of the kind.Is the nominal contact Angle is 90 ° of thrust bearing, such as thrust ball bearing, etc

Rigid [1] refers to the two objects collide not happen deformation, so the two rigid bodies will not occupy the same space, particles, atoms is such substances. Modern furniture manufacturing technics.System furniture under static load, the ability to resist deformation.Industry, mechanical stiffness, is also an important index of a mechanical. In mathematics, rigid equation refers to a differential equation, the solution of stable only in the time interval is very small, as long as the time interval is a little big, the solution will be unstable.Difficult to accurately define which differential equation is rigid equation, but general idea is: part of the equation solution contains a rapid change. For example, in terms of the numerical simulation of the plasma, as a result of the plasma body cavity indoor electronic relative to the ion mobility is bigger, to solve the electronic related physical quantities, if the time step is too big, can't high accurate simulation of the electron motion, so it's no meani

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.
