introduction：Tapered roller bearingsIt belongs to the separation type bearing，Bearing insides、The outer rings have conical raceways。This type of bearing is divided into a single row according to the number of rows of rollers installed、Double row and four row tapered roller bearings and other different structural types。Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction。When the bearing is under radial load，Theres going to be an axial component，So when you need another bearing that can withstand the axial force in the opposite direction to balance it。

introduction：Teflon conveyor beltBe divided into two，One is the Teflon high-temperature cloth conveyor belt，The other is a Teflon mesh conveyor belt。 Main performance characteristics of Teflon high temperature conveyor belt： 1、Resistance to bending fatigue，Can be used for smaller wheel diameters。 2、For low temperature-196℃，hyperthermia300℃among，It is resistant to weather、anti-aging。Through practical application，As in250℃Place continuously at high temperature200day，Not only does the intensity not decrease，And it doesnt lose weight；in350℃Place at high temperature120hours，Weight loss only0.6％around；in-180℃The original softness can be maintained under ultra-low temperature。 3、Chemical resistance，Strong acid、Strong base、Aqua regia and corrosion of various organic solvents。

introduction：Current relay physical wiring diagram A current relay is an electronic control device，It has a control system（Also known as input loop）And the controlled system（Also known as output loop），It is usually used in automatic control circuits，It actually uses a smaller current to control a larger current“Automatic switch”。The current relay is a switch element that protects the human body，Thats why its so important at the beginning，If you get it wrong, it wont work，The following by Feng Ye Xiaobian teach you how to correct wiring！

introduction：It has many trenches With the development of automation machinery industry，More and more machines and equipment cannot be transmitted without the synchronous belt。It has many trenches（Multigrain tape，Wedged belt）It refers to the flat belt as the matrix、The inner surface is arranged longitudinally with equal spacing40°Trapezoidal wedge ring rubber belt，The working face is the side of the wedge。For the common use of multi-furrowed belts，I believe that some people do not understand its characteristics，The following Feng Ye Xiaobian will take you to understand。

introduction：Steel high temperature resistant linear bearings： Operating temperature at150℃The bearings used above are called high temperature bearings。Due to chromium bearing steel in use temperature exceeds150℃~Cwhen，Its hardness will drop sharply，Dimensional instability，And cause the bearing to not work normally。So for the operating temperature at150℃~E～250℃The bearing works under conditions，If the ring and rolling body are still made of ordinary high-carbon chromium bearing steel，It is necessary to carry out special tempering treatment for bearing parts，Generally, it should be higher than the operating temperature50℃Next to temper。Bearing steel tempered according to the above requirements，It can be used normally at operating temperature。However, the hardness decreased after tempering，Bearing life is reduced。When the bearing operating temperature is higher than250℃when，It must be made of high temperature bearing steel。
