ntnBearing type inquiry ntnBearing is an important part of todays mechanical equipment。It is mainly a part that supports a rotating shaft or other rotating parts,Guided rotational motion,And bear their radial and axial loads,And keep them in the right place at the same time。 ntnThe bearing has developed into one of the important tight accessories of modern machinery,And formed a complete production bearing industrial system。Widely used in automobiles、tractor、Locomotive and locomotive、boats、Machine tool,And various mines、metallurgy、petrification、agriculture、Engineering and other machinery、instrumentally。
Aligning roller bearings have double rows of rollers,Have an outer ring1One common spherical raceway,With an inner ring2raceway And inclined to an Angle relative to the bearing axis。This ingenious construction enables it to have automatic aligning performance, Therefore, it is not easy to be affected by the Angle of shaft and bearing box seat on the error or shaft bending,Suitable for mounting errors or shafts Deflection caused by Angle error。The bearing can bear radial load in addition,It can withstand both directions Use the axial load。 Self-aligning roller bearingsThe inner holes are cylindrical and conical,The taper of the conical taper hole is1:30 and1:12Two kinds of,The conical bore bearing is provided with a set sleeve or a release sleeve,The conical inner hole can be adjusted Heart ball bearing is convenient、Quickly assemble on optical shaft or ladder shaft。 Aligning roller bearing models are:Self-aligning roller bearings(20000CCtype);Taper hole aligning roller shaft bearing(20000CCKtype);Sel
ntnBearing Dongguan dealer NTNBearing dealerBe plentiful in,But many friends are still worried about buying fake goods。When buying bearings,If we can andNTNBearing dealer cooperation,Can reduce the risk of buying fake goods,The price is also relatively favorable。
ZWZbearingIt is a kind of rolling bearing,Rolling bearings change the sliding friction between the running shaft and the shaft seat into rolling friction,A precise mechanical element that reduces friction losses。Rolling bearings generally consist of inner rings、Outer ring、The rolling body and the cage are composed of four parts,The function of the inner ring is to match and merge with the shaft to rotate together;The function of the outer ring is to cooperate with the bearing seat,Play a supporting role;The rolling element is evenly distributed between the inner ring and the outer ring by means of a cage,Its shape, size and quantity directly affect the performance and life of rolling bearings;The cage allows the rolling element to be evenly distributed,Prevent the rolling element from falling off,Guide the rolling element to rotate to lubricate。
Conveyor beltIn transportation and storage,Keep clean from direct sunlight, rain and snow,Prevention and acid、alkali、Oils、Organic solvents and other substances contact,And a meter away from the heating device。 The warehouse temperature should be kept at18-40 ℃among,The relative humidity should be kept at 50- 80 %among。 Storage period,Conveyor belts shall be placed in rolls,non-folding,It should be turned once a quarter during storage。 Different types、The conveyor belts with the number of specifications should not be used together,The joint is best bonded。 Conveyor belt type、structure、specification、The number of layers should be selected reasonably according to the conditions of use。 Conveyor belt running speed generally should not be greater than 2 .5 meter/seconds,Large clumpiness,Low speed should be used as far as possible for materials with high wear and for fixed discharge devices。
AmericaMTSDisplacement Sensor Systems was founded1951years,It has rapidly developed into a market leader in mechanical testing and mechanical simulation systems and industrial automation measurement。AmericaMTSDisplacement sensorSystems Company is on the market to provide magnetostriction(MagnetoSTrictive)Pioneer in displacement measurement technology,Its innovation technology and technical support MTS The company has been in a leading position in the market,And in a number of countries set up branches or offices,And set up Guangzhou Nanchuang sensor division in China,It can provide the best service and solution for the users experiment and production。MTScompany-produced Tempo Sonics Magnetostrictive linear displacement sensors are suitable for many different industrial automation industries,To provide an innovative and reliable quality option for the precise measurement requirements of the industry。from70Date of development,More than a million sensors have been installed in various industrial environments。
RBCThe operating environment of bearings:According to the use of parts and use conditions and environmental conditions to select the size、precision,Suitable bearings are the prerequisite to ensure the life and reliability of angular contact ball bearings。

leserHigh pressure safety valve High pressure safety valve is a kind of safety protection valve,Its opening and closing parts are in a normally closed state under the action of external forces,When the medium pressure in the equipment or pipe rises,It automatically opens when the specified value is exceeded,Prevent medium pressure in pipelines or equipment from exceeding specified values by discharging medium outside the system。
leserMain safety valve leserThe main safety valve is in a normally closed state under the action of external force,When the medium pressure in the equipment or pipe rises beyond the specified value,A special valve that prevents the pressure of the medium in the pipe or equipment from exceeding specified values by discharging the medium outside the system。
