Judge ntn corner exposed to trouble of ball bearing damage and adjust the preloading method


12th December 2013 Bearing Technology 0 Comments
From peeling off, impression, corrosion, crackle, abrading,etc. will reflect seeing in the vibration measurement of the bearing, it is very responsive that ntn bearing shakes the damage to the bearing, so, the angle contacts the ball bearing through adopting the special bearing to shake the measurer frequency analyser,etc. Can measure the vibrating magnitude, assign to and can't educe the out of order detailed conditions through the frequency. Different because of using the sensor erection site of conditioned disjunction to wait for of the bearing because of number values that is measured, so ...

The angle is exposed to the basic shaft system that the ball bearing is used to be traditional


4th September 2013 Bearing Technology 0 Comments
Cut the basic shaft system of the lathe with numerical control gold, as its name suggests have high rotation speed, but this does not have rigorous demarcation line. For that regarded as machining center and numerical control milling machine which cut the representatives of lathes, it is greater than or equal to the main shaft system of 10,000r/min to refer to the highest rotational speed the same, and have high angles to add reduce correspondingly The speed, in order to realize the instant of the basic shaft hoists or lower the speed and start-stop. In order to meet the manufacturing ...

The angle of uniline is exposed to the structural style of the ball bearing


4th September 2013 Bearing Technology 0 Comments
The angle of uniline has the following structural styles to contact the ball bearing: 1 The angle of separate type contacts the ball bearing The coaxiality of bearing S70000, its outer lane ball track have lock, can separate with inner circle, retainer, the intersection of key link and the intersection of ball and assembly, therefore can install separately. This kind is mostly that internal diameters are smaller than the miniature bearing of 10mm, used for the top trochanter, little electric motor,etc. having the running balancing, noise, vibration, stability in a device of the great ...

QJ the intersection of uniline and corner keeps in touch the ball bearing ‘ Use four point contact) Advantage


4th September 2013 Bearing Technology 0 Comments
QJ uniline angle contacts the ball bearing and adopts four point contact, so have the following advantages: But high-speed operation; Very accurate ' Can control the position of trochanter ; Can bear the huge pure axial load or foot-path axle bidirectionally and combine the load. Its most important characteristic is, the bearing will bear enormous axial load and double ability to operate at a high speed and is rolled into one. In with minor or pre- lighter in load interval cases, the angle of uniline can enable the accurate positioning of pivot to contact the bearing. The ball track of ...

The accurate angle of SUNTHAI high speed is exposed to the method of erection of the ball bearing


4th September 2013 Bearing Technology 0 Comments
The accurate angle of SUNTHAI high speed is exposed to the method of erection of the ball bearing The accurate angle of SUNTHAI high speed contacts the ball bearing, is used mainly in the high-speed rotation occasion lighter in load, require the bearing high-accuracy, high rotational speed, rise in low shaking and certain service life at low temperature. Often make the support in the electric basic shaft of high speed to install and use in pairs, it is key fittings in the electric basic shaft of high speed of grinding machine of interior surface. Main technical indicator: 1.Three Thai bearing ...

The two-bank angle contacts the characteristic of the ball bearing


4th September 2013 Bearing Technology 0 Comments
Retainer Use the two-bank angle which rams the steel plate retainer to be exposed to the suffix about retainer of the ball bearing without. It use have machine process more leading brass from steel ball by entity the bearings of retainer with behind M show the most. The suffix MA means using by the leading retainer bearing of brass entity of the outer lane. Use polyamide 66 retainers of glass-fiber reinforcement ' Suffix TVH or TVP Bearing under steady without being lasted 120 ‚ĄÉtemperature. If the bearing adopts the oil lubricating method, additive then in the oil may shorten the life ...

The angle is exposed to the determination of the running speed of the ball bearing


31st August 2013 Bearing Technology 0 Comments
While producing, the antifriction bearing has a limit at the speed of runtime. This limit speed is contacted the material of the part of the ball bearing to presume by the operating temperature or angle of lubricant. There is open horn in the regular backlash that contacts the ball bearing and uses for the grease lubrication horn and contacts the ball bearing: Lubricant: Contain the regular lithium soap grease lubrication of mineral group oil, the degree of viscosity in 40 degrees Centigrade is from 100 to 200mm2/s such as ISO VG 150 The angle contacts the ball bearing reference burning ...

The angle contacts the ball bearing and presents the noise in use, there are the following aspects mainly


31st August 2013 Bearing Technology 0 Comments
The angle contacts the ball bearing and presents the noise in use, there are the following reasons mainly 1. Lubricating oil or grease variety is selected wrong; 2. It is insufficient oil level and too low to lubricate, the oil or lipoprotein passes the sealed leakage loss ; 3. Horn it contacts backlashes of ball bearing to be too little ' Do not cooperate and choose appropriately ; 4. The angle is contacted and mixed in the ball bearing in impurity such as the sand grain or carbon granule, play abradant function; 5. The angle is contacted and mixed in the ball bearing in the moisture, ...
