Bearing Unit consists of a set of bearing and bearing housing. Or named bearing with pillow block. Most of People say bearing unit are the same with pillow block bearings, But actually Bearing unit have so many kinds of design, Pillow Block Bearings are the most widely used on kinds of Bearing unit the market. According to the type of bearing, there are ball bearing unit, roller bearing unit, ball bearing unit also have insert ball bearing unit(pillow block bearing unit), linear bearing unit and self-aligning ball bearing unit; The roller bearing unit have spherical roller bearing unit. Tapered roller bearing unit. According to different applications, there are have different design just like high-temperature bearing units, stainless steel bearing units, high-speed bearing units, maintenance-free bearing units, ceramic bearing units, corrosion-resistant bearing units, etc.; Bearing housing(Pillow Block or Plummer Block) include cast iron, ductile cast iron, heat-resistant plastic, Stainless steel, ceramic and other designs of different materials. The seals of Bearing Unit we can provide four-star seals, maintenance-free seals, pillow block colors we can produce black, blue and green colour.
Mounted Pillow Block Ball Bearing Unit is one of the most used and widely used types in the market, we can produce a full range of Bearing unit. Here we introduce the ball bearing unit as follows:
Ball Bearing Unit is a kind of bearing unit which combines rolling bearing with bearing housing. Most of the Ball Bearing Unit are made of spherical surface, and are installed with bearing pedestal with spherical inner holes. They have various structure forms, good universality and interchangeability. The internal structure of Pillow Block Bearings is the same as that of deep groove ball bearing.
Although its basic performance should be similar to that of deep groove ball bearings, because this kind of bearings are mostly used in rougher machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole are poorly aligned, or the shaft is long and deflection In the case of large-scale bearings, the accuracy of the bearing itself is not high enough, and some structures are relatively rough, so the actual performance of the deep groove ball bearing of the same specification will be discounted. For example: the Pillow Block Bearings with top wire is applied to the through shaft with large rigidity difference and large deflection. This kind of bearing has seal rings on both sides to prevent the intrusion of dirt. It has been filled before leaving the factory.
The performance of the Ball Bearing Unit with eccentric sleeve and the Pillow Block Ball Bearings with top wire are basically the same, except that the top wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered Pillow Block Bearings is a tapered hole with a taper of 1:12, which can be directly installed on a tapered shaft or on an optical shaft without a shoulder with the aid of a tightening bushing, and the bearing clearance can be fine-tuned.

It is mainly used to bear the combined radial and axial load, which is mainly the radial load. Generally, it is not suitable to bear the axial load alone. This type of bearing can be installed with an inner ring (with a full set of rollers and retainers) and an outer ring. This kind of bearing does not allow the shaft to be tilted relative to the housing, and additional axial force will be generated when the radial load is used. The size of the axial clearance of this kind of bearing has a great influence on whether the bearing can work normally. When the axial clearance is too small, the temperature rise is higher; when the axial clearance is large, the bearing is easy to be 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 used to increase the rigidity of the bearing.
