( With housing ) spherical ball bearings Introduction:

Spherical ball bearings is actually a variant of deep groove ball bearings , is characterized by its outer diameter surface of the sphere , can be equipped into the corresponding concave spherical bearing self-aligning effect.

Although its basic properties and deep groove ball bearings are similar, but because most of the bearings used in the rough mechanical , the installation location is not precise enough , the hole axis and the seat of the neutral difference , or the long axis deflection large etc., but not high enough precision bearing itself , some structures are relatively rough, so the actual performance of the performance of the same size on the fight deep groove ball bearing considerable discounts . For example: spherical ball bearings with the top wire used in stiffness difference , a big pass deflection shaft , the bearings with seals on both sides , can be tight to prevent dirt intrusion , had filled with the right amount of grease at the factory before installation without cleaning, no additional lubricant , the top end of the wire protruding screws on the bearing inner ring in the shaft when tightened , the permissible axial load should not exceed 20% of the rated dynamic load .

With eccentric outer spherical ball bearings and spherical bearings performance with the top wire of the same, just not on the top of the inner wire , but in the eccentric sleeve. Bore tapered bore spherical ball bearings with 1:12 tapered bore taper , can be installed directly on a tapered shaft, or with an adapter bushing is mounted on the shaft shoulder axis , and fine-tune the bearing clearance .

Spherical bearings priority for applications that require simple equipment and spare parts occasions , such as for agricultural machinery , transportation systems or construction machinery.

Spherical ball bearings are mainly used to bear radial load mainly radial and axial loads , generally should not alone bear the axial load bearing does not allow this kind of tilt axis relative to the housing . Under radial load , will produce additional axial force . This kind of bearing axial clearance of the size of the bearing can work properly when the axial clearance is too small , the higher temperature ; larger axial clearance , bearing easily damaged. Therefore, installation and operation of special attention to adjust the bearing axial clearance , if necessary, preloaded mounting to increase the rigidity of the bearing .

LNSERTED ball bearing type

LNSERTED bearing is a bearing unit rolling bearing and bearing combined. Most of the outer diameter of the outer spherical bearings are made ​​of spherical , installation and spherical bearing bore together with structural diversity, versatility and interchangeability .

Meanwhile, in the design of these bearings also has a certain Mind, easy to install, has a dual structure of sealing device can operate in harsh environments . Bearing casting is generally used . Common blocks are vertical seat (P), a square seat (F), Boss Square Block (FS), Boss round seat (FC), diamond-shaped seat (FL), an annular seat (C), slide seat , etc. ( T).

With spherical bearings into the bearing outer race and housing in the call is bearing housings plus titles, such as set screws with spherical bearings UC205 with Vertical Block , code-named UCP205. LNSERTED has a strong bearing due to the interchangeability , bearing the same specifications can be freely assembled in housings in different shapes .

LNSERTED ball bearing disassembly

Spherical bearings generally through eccentric shaft fixing the bearing inner ring and eccentric sleeve socket head cap screws from tightening effect. Maintenance , many machines are not dismantling the bearings hand , it is necessary to introduce the techniques and precautions removable outer spherical bearings :

Disassembly

1 first with a hex wrench to loosen the eccentric sleeve bearing locking screw , and then cover with a small iron bar sink hole eccentric sleeve , against the direction of rotation of the eccentric shaft to play loose .

2 Loosen the bolt housings . Together with the bearing housings removed from the shaft . Note that the demolition of the shaft end bearing, shaft bearing bolts should be the other end of the release , in order to avoid the presence of interaction between each other at both ends of the bearing damage .

Installation

1 To install the front shaft bearing , you must unplug the fixed pin bearing jacket , while ensuring that the journal surface polished , clean and painted in the journal of the rust lubricant ( allowing the bearing on the shaft slightly rotated ) .

2 in the bearing and bearing with lubricant topcoat , the bearing into the bearing . Then the assembled bearing and housing units along the shaft , pushed to the desired location for installation.

3 fixed bearing bolt , do not tighten , let jacket bearing in the housing can rotate . Also installed the other end of the same shaft bearings and the seat of the shaft a few times , so that the bearing itself automatically find the positive position, then the bearing bolt is good.

4 mounted eccentric . Eccentric condom on the first step in the eccentric sleeve bearing , along the axis of rotation and hand tighten , then a small iron bar sink hole insert or withstand eccentric sleeve , hand direction along the axis of rotation of the hammer hitting the small iron , so eccentric securely installed , and finally locking hex screw eccentric sleeve .

Insert Ball Bearings

Spherical ball bearings and shaft in accordance with the method to points, can be divided into three categories :

First, with the top wire , spherical ball bearings : Its code is : UC200 Series ( light series ), UC300 Series ( heavy series ) , and distortion product UB (SB) 200 series , if the use of the environment with the degree of small, usually pick UC200 Series , otherwise the selected UC300 series. Typically the top wire , spherical ball bearings on the two , its angle of 120 °, its specialty is working with the shaft , with the top wire to the top of the shaft, and then play a fixed role , but the demand is for the environment smaller oscillation amplitude . This spherical ball bearings commonly used , widely used in textile machinery, ceramic machinery and other industries.

Second, tapered , spherical ball bearings : Its code is : UK200 series , UK300 series. Such spherical ball bearing inner diameter of 1 : 12 taper bore , to cooperate with the tight sets use when applying . Such spherical ball bearings features as : the ability to accept than with the top wire , spherical ball bearing larger loads . Due to cooperate with the same type of tight sets with the top wire than the inner diameter of the spherical ball bearings smaller, for example, with an inner diameter of the top wire , spherical ball bearings UC209 is 45mm, with its diameter of the shaft relative to cooperative use of 45mm, and if replaced with taper spherical ball bearings , it can only pick inner diameter of 45mm adapter sleeve , and cooperation with 45mm tapered adapter sleeve , spherical ball bearings only with UK210 (of course with better words if possible the selection UK310 ) . Thus , UK210 acceptable fit of course much larger than the UC209 .

Third, with eccentric outer spherical ball bearings: Its code is : UEL200 series , UEL300 series , SA200 Series . Such spherical ball bearings for the end of the primary characteristics of a certain degree of eccentricity on bearing with the same eccentricity with its eccentric . Such bearings can also be said to be special bearings , which is mainly used in agricultural machinery ( harvesters, straw machines, threshers , etc.) , such a spherical ball bearings used in the case of relatively strong beat , with eccentric structure can effectively reduced the strong beat.
