29240E Spherical roller thrust bearings
 
 
 
Specifications:

Spherical roller thrust bearing with special design of raceway, equipped with a large number of asymmetric roller.Have a perfect fit between race, so as to optimize the load distribution on the roller.As a result, they used in high speed, on the one hand, under high axial load, on the other hand, withstand high radial load applications.To load with the bearing axis at an Angle from one race to another race.Spherical roller thrust bearing is a kind of since the self-aligning bearing, can withstand the axial deviation between shaft and bearing caused by factors such as static in the wrong.
 
Basic information edit this paragraphThrust roller bearing is used to carry axial load of axial, radial joint load, the radial load shall not exceed 55% of the axial load.Compared with other thrust roller bearings, the bearing friction factor is low, high speed, and has a self-aligning performance.Related matters to edit this section
 
1. Have a look at the choice of thrust roller bearing chamber tolerance and control: after the thrust roller bearings thrust roller bearing pressure should be flexible rotation without blocking.If there are any obvious rotation is not flexible, indicates the size of the shaft is too big, tolerance to downgrade.Such as thrust roller bearing pressure into the shaft by hand after the rotation has obvious "sasha vujacic" feeling, may be the shaft or shaft roundness tolerance is too big.So in good control of shaft and thrust roller bearing chamber of tolerance when also want to control the roundness, at present many domestic manufacturers to control the tolerance only, not to control the roundness.
 
2, thrust roller bearing assembly way: because the thrust roller bearing is high precision products, such as improper assembly is easy to cause damage to the thrust roller bearing channel, lead to damage of thrust roller bearing.Thrust roller bearings in the assembly shall have a dedicated mold, not casually, only small circle of stress when pressure into the shaft, pressure can force the circle circle.Require the use of pneumatic or hydraulic assembly, lower die when being connected to outside the state level, such as with sloping channel leads to thrust roller bearing due to mechanical damage, and make the guide ring thrust roller bearings.
 
3, the assembly to prevent foreign body: thrust roller bearings when loaded on the rotor to do dynamic balance will easily generated when the dynamic balance of iron into internal thrust roller bearings, so it is best to do dynamic balance before loading thrust roller bearing.There are some manufacturers in order to convenient assembly, assembly in indoor thrust roller bearing with some oil or grease lubrication effect, but usually operators good amount of it is hard to control, if oil or grease in the indoor storing up more thrust roller bearings, thrust roller bearing rotating when along axis to the thrust roller bearings inside easily.Thrust roller bearing chamber is best not to apply oil or grease, if must apply to control shall not be storing up in thrust roller bearing interior.
 
4, paint, rust prevention: paint rust is characterized by multiple in sealing type motor, the motor sound is very good, when it is assembled but put some time in the warehouse, the motor sound is very big, remove the thrust roller bearings with serious rust phenomenon.Before a lot of manufacturers will think is a problem of thrust roller bearing, through our continuous publicity, motor factory now have realized mainly is a question of insulating varnish.Acid varnish comes out of the problem is mainly due to the formation of corrosive substances under certain temperature, humidity, the thrust roller bearing channel after corrosion lead to damage of thrust roller bearing.The problem now is only to choose good insulating paint, after drying and ventilation assembly after a period of time.
 
Edit this section product featuresUsed to carry axial load of axial, radial joint load, radial load of not more than 55% of the axial load.Compared with other thrust roller bearings, the bearing friction factor is low, high speed, and has a self-aligning performance.
 
Type 29000 stick for asymmetric spherical roller bearing, can reduce the relative sliding roller and race in the work, and roller is long, large diameter, roller number, high load capacity, usually adopt oil lubrication, individual is lubricated by grease at low speed.While selecting a design, should first selection;
 
80000 type thrust cylindrical roller bearings, the type 90000 type thrust tapered roller bearing and AXK thrust needle roller bearing, can bear the axial load of one-way, it is bigger than thrust ball bearing axial load capacity is much, and large rigidity, axial space is little.
 
Thrust cylindrical roller bearings, thrust taper roller bearing is suitable for low speed, speed slightly higher than the thrust tapered roller bearing thrust cylindrical roller bearings.Separated type thrust cylindrical roller bearing is a bearing and can only carry axial load one-way and slight shock, to restrict axis (or shell) in one direction axial displacement, thus can be used as a one-way axial positioning.But its carrying capacity is far greater than thrust ball bearing.Due to linear velocity is different on both ends of the roller, roller rolling make the roller in the roll ring road inevitably produces sliding, as a result, this kind of bearing limit rotational speed is low thrust ball bearing, usually only suitable for low speed occasion.
 
Standard design of thrust roller bearing used car metal solid cage, according to user requirements, also can use other type or material of the cage.Thrust tapered roller bearings can only carry a one-way axial load, one-way axial displacement can limit bearing, so it can be used as a one-way axial positioning.Compared with cylindrical roller thrust bearing, large carrying capacity, relative sliding is small, but limit rotational speed is low.
 
Product use edit this paragraphThrust cylindrical roller bearing is mainly used in heavy duty machine tools, high-power Marine gearbox, oil drilling machine, vertical machine and other machinery.
