Spherical Bearings

Spherical bearing is a variant from Deep Groove Ball Bearing actually,is characterized by its outer diameter surface of the sphere, can be blended with a bearing block corresponding concave spherical bearing self-aligning within the role play.

Although its basic performance with the deep groove ball bearings should be similar, but because most of the bearings used in the rough machinery, the installation location is not precise enough, shaft and housing bore axis of the neutral difference, or the long axis of the deflection and large cases, and the precision of the bearing itself is not high enough, some structure is relatively coarse, so performance is same as the actual performance specifications deep groove ball bearings play on a considerable discount. For example: with the top wire of the outer spherical ball bearings used through the large stiffness difference deflection shaft, the bearings on both sides with a ring, to tight to prevent dirt intrusion, the factory had filled the right amount of lubricant before installation without cleaning, No additional lubricant, the bearing inner ring on the top of the wire protruding end of screw fastening on the shaft. Permissible axial load shall not exceed dynamic load rating of 20%.

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

Spherical Bearings priority for applications that require simple equipment and spare parts where, for example, agricultural machinery, building transportation systems or machinery.

Mainly used to bear radial load mainly radial and axial joint load, generally should not alone bear the axial loads, such bearings can be installed inner ring (with the whole group of roller and cage) and the outer ring. This kind of bearing does not allow a tilt axis relative to housing, the radial load at the next appointment will produce additional axial force. This kind of bearing axial clearance of the size of the bearing can work in it when the axial clearance is too small, the higher temperature; axial clearance is large, easy to damage the bearing. Therefore, in the installation and operation should pay special attention to adjust the bearing axial clearance, if necessary, can be preloaded when installed, to increase the bearing stiffness.

Spherical bearings including types :

Spherical bearings
Such bearings are also designed with a certain tone heart and mind, easy to install, has a dual structure of the sealing device that can work in harsh environments. Bearing cast molding is generally used. Common block has vertical seat (P), a square block (F), Boss Tower Square (FS), Boss circular seat (FC), diamond-shaped seat (FL), seat ring (C), the slider block, etc. ( T).

Spherical bearings are roller bearing and the bearing of a bearing unit together. Most spherical bearings are made of the diameter sphere, and with a ball bearing installed within the hole together, structural diversity, versatility and interchangeability.

Meanwhile, also in the design of these bearings has a concentric tone, easy to install, has a dual structure of the sealing device that can work in harsh environments. Bearing cast molding is generally used. Common block has vertical seat (P), a square block (F), Boss Tower Square (FS), Boss circular seat (FC), diamond-shaped seat (FL), seat ring (C), the slider block, etc. ( T).

Spherical bearings into the bearing center and housing, based on the name for bearing with bearing seat call center, such as set screws with spherical bearings UC205 with Vertical Block said UCP205.Spherical bearings as highly interchangeable, bearing in mind the same specifications can be freely assembled bearing in different shapes.

Spherical Bearing disassembly :
390 000 series, spherical bearing is eccentric to the bearing inner ring and shaft, put the eccentric socket head cap screw from tightening effect. In maintenance, many machines will not be dismantling the bearing hand, it is necessary to introduce the spherical bearing disassembly 390,000 series of technical issues and considerations:

Disassembly :

1. First with a hex wrench to loosen the locking screw bearing eccentric sleeve, and eccentric with a small iron bar into the roof put on the sink hole, going against the axis of rotation to play loose eccentric sleeve.

2. Loosen the fixed bearing bolts. Together with the bearing from the shaft bearing removed. Note that the demolition of one end of the bearing before the shaft. Should be the other side of the bearing shaft bolts loose, so as not to each other at both ends of the bearing strength and damage.

Installation :

1. Bearing to the shaft before installing, you must first remove the fixed pin bearing jacket, while the journal surface polished smooth clean, oiled and rust in the journal office and lubrication (bearings in the shaft to allow a slight rotation).

2. Bearing in the bearing with the top coat with oil, the bearing into the bearing seat. Then assembled with the bearing and the bearing sleeve on the shaft. Pushed to the desired location for installation.

3. Fixed bearing, do not tighten the bolts, let the jacket bearing can rotate within the bearing.Also installed the other end with a shaft bearing and seat, the axis of rotation a few times, so that the bearing itself automatically find the location is. Then tighten the bolts a good bearing.

4. Loaded eccentric. Condom at first eccentric eccentric sleeve bearing on the steps and along the axis of rotation by hand tighten. Then insert a small iron bar or put on the sink hole to withstand eccentric. Hand-hammer percussion along the axis of rotation of small iron bar. The eccentric sleeve is securely mounted, and finally put the locking eccentric socket head cap screw.

Applications :
Transmission system, Agricultural machinery , Pumps , Mining , Marine Textile machinery, Printing Machinery Automotive applications .
