Pillow Block Bearing 2 Inch

Pillow block bearing is actually a variant of deep groove ball bearing, 2 inch pillow block bearing is a kind of outer spherical bearing, model is UCPX10-32. The characteristic of pillow block bearing is that the outer diameter surface of its outer ring is spherical, which can be matched into the corresponding concave spherical surface of the bearing seat to play the role of centering. The pillow block bearing is mainly used to bear the combined radial and axial load mainly based on the radial load, and it is generally not suitable to bear the axial load alone.

All models of pillow block bearing

What is pillow block bearing?

Although its basic performance should be similar to that of deep groove ball bearings, because these bearings are mostly used in relatively rough machinery, the installation and positioning are not accurate enough, the axis alignment between the shaft and the seat hole is poor, or the shaft is long and deflected. In the case of large and other, and the bearing itself is not high enough precision, and some structures are relatively rough, so the actual performance of the deep groove ball bearing of the same specification should be marked with a considerable discount. For example: the outer spherical surface ball bearing with top wire is used in the through shaft with large stiffness difference and large deflection. This kind of bearing has sealing rings on both sides, which can strictly prevent the intrusion of dirt. It has been filled with an appropriate amount of lubricant before leaving the factory and does not need to be cleaned before installation. No need to add lubricant, when the top screw on the protruding end of the bearing inner ring is fastened on the shaft. The allowable axial load shall not exceed 20% of the rated dynamic load.

The pillow block bearing with eccentric sleeve has basically the same performance as the pillow block bearing with top wire, but the top wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered hole pillow block bearing is a tapered hole with a 1:12 taper, which can be directly installed on the tapered shaft, or installed on the shoulderless optical shaft with the help of a tight bushing, and can fine-tune the bearing clearance. Pillow block bearings are preferably used in applications requiring simple equipment and components, such as agricultural machinery, transportation systems or construction machinery.

The 2 inch pillow block bearing is mainly used to bear the combined radial and axial load mainly based on radial load. Generally, it is not suitable to bear the axial load alone. The pillow block bearing can be installed with the inner ring (with a full set of rollers and cages). ) and the outer ring. This kind of bearing does not allow the shaft to be inclined relative to the housing, and additional axial force will be generated under the radial load. The size of the axial clearance of this kind of bearing has a great relationship with whether the bearing can work normally. When the axial clearance is too small, the temperature rise will be high; when the axial clearance is large, the bearing is easily damaged. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre-interference installation can be performed to increase the rigidity of the bearing.

2 inch pillow block bearing Important factors for proper operation and extended service life

The choice of lubricant is an important factor in ensuring proper bearing operation and extending its service life. Lubricants do the following:

Makes movement easier; Avoids wear and material fatigue; Reduces internal friction; Ensures bearings are sealed from external objects; Reduces operating noise; Protects bearings from corrosion.

You have two options: grease or oil.

In general, grease lubrication is definitely the easiest and most efficient option because it has all of the above features and is less expensive to maintain. However, if your bearings are integrated in an oil lubricated machine, we recommend that you use the same lubrication system.

In any case, the choice of lubricant depends on three factors: load, type of operation (continuous or intermittent) and rotational speed.

If bearings are prone to high loads, operate continuously and rotate at high speeds, oil lubrication is the ideal solution to ensure the proper functioning of rolling systems.

Conversely, if the load is low and the speed is limited, then grease is sufficient.
