Pillow block bearing unit is a bearing unit that combines a rolling bearing with a bearing housing. Most pillow block bearings are made of spherical outer diameter and are installed with pillow block which have spherical inner holes. They have various structural forms, good versatility and interchangeability.

The design of the UCPA series ball Bearing unit also has a certain degree of self-aligning, easy to install, with double structure sealing device, which can work in harsh environment. UCPA bearing block is generally cast. Other common types of bearing housing are UCP, UCF, UCFS, UCFC, UCFL, UCT etc.

Pillow blocks can refer to a variety of bearing styles such as single row ball bearings, double row ball bearings, spherical roller bearings, taper roller bearings, etc. A unit is typically a reference for a 1-piece housing as opposed to a split housing. For simplicity, this article will focus on single row ball bearing units.

UCPH bearing is a type of bearing unit. This bearing unit is also a combination of PH bearing housing and pillow block bearing. UCPH bearing seat is much higher than other types of bearing housing, mainly used in special installation environment. The bearing housing is mainly made of cast iron, and stainless steel and plastic materials are used less than cast iron. The pillow block bearing is the same with the other types of mounted bearings unit.

The insert ball bearing is a variant of the deep groove ball bearing. the outer diameter surface of the outer ring is spherical, which can be fitted into the corresponding concave spherical surface of the bearing housing to play the role of centering. The insert ball bearing 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

Although its basic performance is similar to that of deep groove ball bearing, most of the bearings are used in relatively rough machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole is neutral, or the shaft is long and the deflection is large, and the accuracy of the bearing itself is not high enough, and some structures are relatively rough, so the actual performance of the bearing is relatively the same specification Deep groove ball bearings are subject to considerable discount.

The code of Insert ball bearing with set screw is uc200 series (light series), uc300 series (heavy series) and UB (sb) 200 series. If the application environment is small, uc200 series is usually selected on the applications,, otherwise uc300 series is selected. Generally, there are two jackscrews on the spherical surface ball bearing, with an included angle of 120 °.

Generally, there are two jackscrews on the spherical surface ball bearing, with an included angle of 120 °. The characteristic is that the jackscrew is used to Jack the shaft when cooperating with the shaft, and then it has a fixed effect. However, the cooperation environment needs to have a small oscillation scale.
