Product Description


Pillow block bearing is a bearing element that combines rolling bearing and bearing seat. Most of the outer spherical bearings are made of spherical outer diameter, with spherical inner hole of the inlet bearing seat installed together, the structure of a variety of forms, versatility and good interchangeability.



The pillow block bearing is the outer spherical bearing we usually call. The reason why it is called the ball bearing is because it belongs to the deep groove ball bearing, and the rolling element inside is the steel ball.

Pillow block bearings are more convenient to use than deep groove ball bearings. Its main features are simple loading and unloading and can be adjusted. The standard tolerance of the pillow block bearing is: internal plus external subtraction, and the inner diameter is adjusted to ensure the lightness when mating with the shaft. The bearings are not used separately. They must be fitted to the inner part of the bearing housing. The pillow block housings have various shapes and are suitable for a variety of structural positions. Pillow block bearings can be divided into three categories according to the way they are matched with the shaft:


1.With fastening screws:

Its codenames are: UC200 series (light series), UC300 series (heavy series), and UB (SB) 200 series. If the environmental load is small, the UC200 series is generally selected, otherwise the UC300 series is used. Generally, there are two fastening screws on the pillow block bearing, and the angle is 120°. The characteristic is that when the shaft is matched, the fastening screw is used to mount on the shaft, thereby playing a fixed role. Environmental requirements: The vibration range must be small. Such pillow block bearings are relatively common and are widely used in various manufacturing industries such as textile machinery and ceramic machinery.



Its code name is: UK200 series, UK300 series. This type of pillow block bearing has a 1:12 ratio taper inner bore and should be used with the adapter sleeve when in use. Features: Ability to withstand greater loads. Performance under high load conditions is significantly better than pillow block bearings with fastening screws.


3.With eccentric sleeve:

Its code name is: UEL200 series, UEL300 series, SA200 series. The main feature of this type of pillow block bearing is that the bearing has a certain degree of eccentricity at one end. An eccentric sleeve with the same eccentricity is matched with it. Such bearings can also be said to be special bearings, because they are mainly used in agricultural machinery (harvesters, straw returning machines, threshers, etc.). These pillow block bearings are mainly used in structures with relatively strong vibrations, eccentric structures. Cooperation can effectively reduce the violent vibration.


4.Double seal / three layer seal

Another feature of pillow block bearings over other common bearings is the double-layer seal, because the environmental conditions of the pillow block bearings are harsh, especially in the case of agricultural machinery bearings. The double seal ensures that dust does not easily enter the interior of the channel. In addition, our company's three-layer three-lip sealed outer spherical bearing greatly enhances the dustproof capacity and prolongs the service life of the bearing.

At the same time, this kind of bearing in the design also has a certain degree of centralization, easy to install, with a double structure of the sealing device, can work in bad environment. The bearing seat is generally cast. Commonly used seat has vertical seat (P), square seat (F), convex square seat (FS), convex circular seat (FC), diamond seat (FL), ring seat (C), slider seat (T) and so on.
