Pillow Block Bearings

Pillow Block Bearings

Product Description
Pillow block bearings are composed of the outers spherical ball bearings with double-seal and the casting pedestal(or pressed steel plate). The inside structure of the pillow block bearings is the same as deep groove ball bearings, however the outer ring of this type has the outer surface of section balls, it can be Self-aligning when fitted with concave of the bearing pedestal. Generally there are clearance between the inner bore and shaft, we must fixed the inner ring with the shaft by tip wire, eccentric sleeve or clamping sleeve, then the bearing could rotate with the shaft. The pillow block bearings are compact in structure, convenient for assembling and disassembling. They are suitable for simple support. They are often used in mining, metallurgy, agriculture, chemical, transmission machinery and other industries.
The main structure type of bearings:
1. With tip wire: This type can be used in the situation of changeable rotate direction, it includes two forms: UC with wide inner ring and SB with one flat end inner ring.
2. With eccentric sleeve: This type can be used in the situation of steady rotate direction, it includes two forms: NA with wide inner ring and SA with one flat end inner ring.
3. With clamping sleeve: UK+H: With wide inner ring and the inner diameter are tapered hole. This type can be used the situation of changeable rotate direction and high speed, at the same time, rotation is more reposeful than above two types.
4. Wide inner ring and with tip wire: SER: The surface of out ring is cylindrical. This kind of bearings can be combined with shell directly, it needn't the bearings pedestals.
