Paired tapered bearing purposes described

  Paired tapered bearing mainly exposed to the radial radial and axial load. Load bearing capacity depends on the outer ring raceway angle, angle the greater carrying capacity. These bearings are separable bearings, according to the number of columns bearing rolling elements into single row, double row and four row tapered roller bearings. Tapered roller bearings have tapered inner and outer ring raceways, tapered rollers are arranged between the two. All conical surface projection lines are a little get Tapered roller bearings  with the bearing axis. This design makes tapered roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. Single row tapered roller bearings have an outer ring, the inner ring and a set of tapered roller by basket-shaped cage into an inner components. Tapered roller bearings are mainly used to bear radial load mainly radial and axial joint load. Compared with angular contact ball bearings, single row cylindrical roller bearing  capacity, low speed limits. Tapered roller bearings can withstand axial load in one direction, a direction to limit the axial displacement of the shaft or housing. The ability to single row tapered roller bearing axial load depends on the contact angle, ie the angle of the outer ring raceway, the greater the angle, the greater the axial load capacity. Tapered roller bearings are up to the amount of single row tapered roller bearings. In the car's front wheels, and spend the small size of the double row tapered roller bearings. Four tapered roller bearings used in large-scale cold rolling mill and other heavy machines.

a polymer-dispersed liquid crystal

Between the solid and the liquid crystal is in a liquid organic substance having a certain orderly, with the dynamic optical scattering characteristics; which has a variety of liquid crystal phase, such as cholesteric phase, a smectic phase variety, the columns are equal. Depending on the nature of the material, each Stainless steel slewing bearing‍ phase of the liquid crystal material have been developed for large flat panel display devices, there has been developed a variety of nematic liquid crystal, a polymer-dispersed liquid crystal, a double (multiple) type liquid crystal, a ferroelectric  backing bearings‍ and anti-ferroelectric liquid crystal displays, including the development of the most successful, the market share of the largest and fastest-growing is the nematic liquid crystal displays. The liquid crystal display material is composed of a variety of small molecule organic compounds, the main structural feature of these small molecules are rod-like molecular structure. With the rapid development of  people interested in research and development of liquid crystal material is growing.
