hybrid bearings Precautions

Hybrid Hybrid bearings are sliding bearings in one, it is to work in a fluid state energy lubricated plain bearings, while static Hybrid bearings can operate under hydrostatic lubrication and hydrodynamic lubrication. When we pressed hybrid bearings in the movement need to pay attention to the following six things, prevent static journal bearing failure during use.
1, the normal use should be replaced 2 # spindle oil and coarse and fine filter after one year.
2, be sure to join the three-layer silk cloth filter during normal use pumping stations to add oil.
3, spindle pulley, wheel loading and unloading must be carried out in the state of the pumping station work. That spindle under hydrostatic oil floating state. This does not damage the spindle and Hybrid Bearing manufacturers.
4, the front wheel spindle work and grinding hydrostatic pressure pumping observation is within specification range.
5, when the device is shut down, it must first stopped grinding motor, until wheel stop, then turn off the pump station, or easy to damage the grinding head.
6, for any component on the pumping station, be sure to remove the high-pressure inlet hose fittings, complete replacement parts, oil self circulation 15-20 minutes before the inlet pipe connected to the grinding head, thus ensuring into the grinding spindle oil is filtered through fine super clean spindle oil. This can prolong the life of the hybrid spindle.

Precision angular contact ball bearings

In the several bearings to precision angular contact ball bearings most widely used. We all know that angular contact ball bearing rolling body is ball; because it is a point contact (as opposed to line contact roller bearings), so it can provide higher speeds, less heat and higher rotational accuracy. In some super-high-speed spindle applications, but also the use of ceramic balls (typically Si3N4 or Al2O3) hybrid bearings. Compared with the traditional full hardenability ball, ceramic ball material itself characteristic gives ceramic ball bearings with high stiffness, high speed, high temperature, long life, to meet customer demand for high-end products bearing the machine.
On angular contact ball bearing contact angle, the more popular 15 and 25 of the contact angle;???? 15, the contact angle is usually a relatively high speed performance, while 25 of the contact angle with high axial carrying capacity. Due to the impact of the choice of pre-loaded precision angular contact ball bearing applications is very large, for example, in high load, high rigidity of the occasion, the general will choose medium or heavy Bearing manufacturing machine preload; and for some high-speed, high-precision applications We in the early selection of the bearing, need to pay attention to choose the right pre-load, general light preload more common. Preload generally divided into light, medium and heavy three; in order to facilitate the customer's use, now several major bearing manufacturer in the world are generally available previously ground bearing end faces plus preloaded bearing, which is what we usually refer to the universal matching precision angular contact ball bearings form. This kind of Wind turbine bearing preload adjustment eliminates the customers, thus saving installation time.

Advantages of single ball bearings

Advantages of single ball bearings


(1 Ball+1 sleeve a single ball bearing is the improvement of traditional oil bearing, sliding friction and rolling friction mixed, in fact, Slewing bearing is to use a ball bearing paired with an oily bearings to reduce the cost of double ball bearing, it between the rotor and the stator with ball for lubrication, and with lubricating oil. It overcomes the problem that the life of the oil bearing is short, the operation is unstable, and the cost is very limited.

Single ball bearing to absorb oil bearing and double ball bearing has the advantages and the bearing service life of up to 40000 hours, the disadvantage is in after entering into the ball, and the running noise is increased, insert ball bearing but still less than the double ball bearing.

Presided over a number of provincial scientific and technological projects and the state standards, radial clearance ,provincial and ministerial level scientific and technological progress award a third prize 3, the municipal science and technology progress, fatigue testing machine ,each two second prize, a number of technical innovations included provincial scientific and technological achievements, won 7 national invention patent.

Bearing manufacturers and oil bearing

Major radiator bearing manufacturers in bearings with the launch of the new technology in recent years, such as magnetic bearing, fluid protection system bearings, hydraulic bearings, rifle bearing, nano ceramic bearing are also on the above the basic form of bearings improved, basic working principle is no change.

Oil bearing sleeve bearing is to use sliding sleeve bearings, Thin section bearing using oil as a lubricant and drag reduction agent, the initial use of operation low noise, low manufacture cost, but the bearing wear serious, life is ball bearing has a big gap.

And the bearing use time, due to the oil seal (computer radiator products can not use high-grade oil seal, in general, is ordinary oil paper), lubricating oil will gradually volatile, sealed angular contact ball bearing and dust will be entering the bearing, causing the fan speed slows down and increase the noise problems, serious but also because of bearing wear caused by severe vibration caused by eccentric fan. These phenomena, either open or seal gas, only buy new fan out.
