introduction：Thrust tapered roller bearings form a very compact bearing configuration，This bearing can bear very heavy axial loads，Not sensitive to impact loads，And good rigidity。It is divided into unidirectional tapered roller bearings and bidirectional tapered roller thrust bearings。
2018-06-15 Reading quantity 360
introduction：The imported needle roller bearing has been vacuum degassed，therefore，The materials used are of high purity、Low oxygen content、Of good quality。The proper heat treatment was then used，The rolling fatigue life of the bearing is obviously improved。 Beyond the above steel grades，By special purpose，High speed steel with excellent heat resistance is also used，Good corrosion resistance stainless steel。 Cage material： Materials for stamping cages，Use low carbon steel。Depending on the use，Brass plates are also used、Stainless steel plate。Cut cage material，Use high strength brass、Carbon steel，Synthetic resins are also used。
2018-06-15 Reading quantity 227
introduction：1. The roller and the raceway are in line contact or repaired line contact，Large radial bearing capacity，Suitable for heavy loads and impact loads。 2. Low friction coefficient，Suitable for high-speed，Limit speed close to deep groove ball bearing。 3. NType sumNUThe type can move axially，It can adapt to changes in the relative position of the shaft and the housing caused by thermal expansion or installation errors，Can be used as free end support。 4. The machining requirements for shaft or seat hole are higher，After bearing installation, the relative deviation of the outer ring axis should be strictly controlled，Avoid contact stress concentration。 5. The inner or outer ring can be separated，Easy to install and remove。

introduction：The operation function of the outer spherical ball bearing The outer spherical bearing is increased after the amount of lubricating oil，Lubricating oil above bearing tile surface，While reducing damage to the oil film，Part of the reason is to avoid direct contact with the shaft and bearing，But in 62 The degree of，Balance is a high balance，Bearing operation risk is too great。 Better handling of bearing oil capsules。Fuel the tank、Tiled open grid tank、Designed to improve shaft lubrication and cooling oil circulation rate。These measures are not decisive。
2018-06-12 Reading quantity 319
introduction：Rod end joint bearing vibration is very sensitive to the damage of rod end joint bearing，exfoliation、impression、corrosion、crack、Wear and tear will be reflected in the vibration measurement of rod end joint bearing，therefore，By using a special rod end joint bearing vibration measuring device(Frequency analyzer)The magnitude of the vibration can be measured，The specific condition of the anomaly cannot be inferred from the frequency division。The measured values vary depending on the service conditions of the rod end bearing or the sensor installation position，Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment criteria。
2018-06-11 Reading quantity 245
introduction：entranceskfThe thread of a bearing has two manifestations：The threads formed on the outer surface of the cylinder are called external threads、A thread formed on the inner surface of a cylinder is called an internal thread。In general，What is the state of the bearing in the form of the thread forming a helix，Why does it form a spiral，Today, Feng Ye engineer and everyone together to open this unsolved mystery。
2018-06-11 Reading quantity 311
introduction：Linear bearings have high hardness outer cylinder and steel ball，Plus strict manufacturing requirements，Plus strict manufacturing requirements，So it has high precision；Use a high tensile resin retainer，Reduced noise volume。 Linear bearings can withstand loads in any direction： Commodity standard language、normalization，The corresponding components are easy to process，It is easy to meet the requirements in assembly。 Product form： The production of linear bearing products are：Normal form、Gap adjustment type、open-type、Lengthened type、And flange type，Convenient for customers to design and use。
