Q:Full use roller bearings
The service is applied to all axle box bearings, including FAG cylindrical roller bearings, spherical bearings and tapered roller NSK bearings. In addition, FAG industry services also provide support to customers in the rail industry who introduce maintenance management systems. INA bearing agent Chinese by helping clients improve internal maintenance procedures, F IS can enhance the data exchange between various departments, and clearly useless procedures, such as entry in IT system and database in different kinds of data. This reduces the cost of raw material management and speeds up maintenance activities. NSK it is very important for the effective maintenance management to install the bearing units rapidly and effectively in china. At the same time, the F IS offers a range of energy saving bearing heaters. Including the FAG Powertimken series induction heater, to enable customers to reduce the installation time of bearing, NSK bearings so as to shorten the downtime, instead of using the traditional heating method (oil bath heating stove, or board). FAG is a research and development partner and supplier of the world's leading Boeing 787 manufacturer. The quality, reliability and efficiency of Schaeffler's aviation bearings, INA bearings, price fits, and performance in extreme conditions, the INA bearing agent provides support for the international space navigation corporation. FAG's bearing technology is used on almost all modern aircraft.
Q:Cylindrical roller and bearing outer ring processing is sheet metal forming?
Rolling bearings are made by special bearing factories and manufactured by precision special machine tools. It is a highly specialized field in mechanical manufacture. Precision bearings are the key parts to determine the accuracy and operation of the machine. At present, China mainly relies on imports (such as Japan NSK bearings) in high precision bearings.
Q:How to check the thrust cylindrical roller bearings?
Bearing dimensions (or bearing samples) have "basic rated load (KN)", this column can be directly detected, in general, according to the use of appropriate multiplied by a (1.2~1.5) safety factor. In accordance with the requirements of the design manual, the equivalent load can be calculated (considering the speed, temperature, load and stability).
Q:Cylindrical roller bearings N216E and N216EM after the code name is different,
Cylindrical roller bearingN216E stands for the bearing retainer as a steel cageN216EM stands for the bearing holder as brass holderThe material of the cage is different (the structure that holds the roller in it for a long time)
Q:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
Bearing accuracy grade standards for, divided into 0, 6X, 6, 5, 4, 2, six grades.The accuracy of bearings is increased in order of magnitude 0, which is adequate for general 0, but requires 5 or higher accuracy when used in other conditions or situations.In most cases, it is sufficient to apply KOYO bearings (tolerance grade PN) with general dimensional accuracy and rotational accuracy. When higher requirements are required, the bearings require higher levels of accuracy, for example, the spindle axis of the machine toolBearing. In order to achieve higher precision requirements, the standard specifies the tolerance levels of P6, P6X, P5, P4 and P2. KOYO also specified P4S, SP and UP tolerances for some special bearings in accordance with company standards.
Q:Does the thrust cylindrical roller bearing need a bearing seat?. Five

Q:Cylindrical roller bearings standard 10
Bearing (Bearing) is an important component of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement and guarantee its rotation accuracy.According to the friction property of the moving element, the bearings can be divided into two kinds: rolling bearing and sliding bearing. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimensions, vibration and noise are relatively large, and the price is higher.Generally, the rolling bearings are composed of four parts: the outer ring, the inner race, the rolling body and the cage. According to the shape of the rolling element, the rolling bearings are divided into two major categories: ball bearings and roller bearings.
Q:What are the materials of the homemade bearings / homemade Zhejiang Tianma cylindrical roller bearings / bearings?
Domestic bearings used in the cage and rivet and washer, spacer ring, sealing ring, pillar, pin etc. the material is divided into black metal materials (such as low carbon steel, stainless steel etc.), non-ferrous metal materials (such as brass, bronze and Aluminum Alloy etc.) and non metal materials (such as plastics, phenolic textolite three) etc..Imported bearings are basically the same as those made in China. There are copper, steel, alloy and so on.
Q:NSK cylindrical roller bearings EW/EM series of differences and characteristics
E international is called "reinforced type" load, also means to increase rolling bodyW international is called a steel cage
Q:What are full cylindrical roller bearings?
Full cylindrical roller bearingCommon cylindrical roller bearings1, single row full cylindrical roller bearingsNCFNJG2 、 double row full cylindrical roller bearingNNCLNNCFNNCNNFTwo, not common full cylindrical roller bearings1, full spherical cylindrical roller bearings2, CARB ring roller bearings
