In many well-known foreign brands SKF bearings, FAG bearings, NSK bearings, NTN bearings, INA bearings; shafts or other components of rotating machinery; generally supported by a fixed end bearing and a floating end bearing. Fixed end bearing refers to A mechanical component is axially positioned in two directions. The most suitable bearing is a bearing that can accept a combined load; or a bearing that can be axially guided when used with another bearing.
A floating bearing is a bearing that can accommodate the axial movement of the shaft. For example, when the shaft is in thermal expansion, the bearing will not receive an excessive rated load. The most suitable bearings are needle bearings, NU and N-type cylindrical rollers. Bearings. NJ cylindrical roller bearings and some full complement cylindrical roller bearings can also be used as floating bearings.
The required amount of axial displacement is relatively large; and there may be applications of viewpoint errors; the bearing of the floating bearing at the CARB bearing is capable of allowing the axial displacement between the shaft and the bearing housing to occur in the bearing. The corresponding product table gives the amount of axial displacement allowed.
For example, the use of deep groove ball bearings or spherical roller bearings and other non-detachable bearings as floating bearings; in the middle of a bearing ring is necessary for the cooperation of the gap.

Screw Pump

There have three type screw pumps: 1. Single Screw Pump. 2. Three Screw Pump. 3. twin screw pump 1. single screw pump usually been used to transfer sludge, mud, sauce etc thick liquid. 2. three screw pump usually beed usde to transfer the temperature not higher than 150 degree diesel fuel oil, lubricating oil etc oil. and heat insulation triple screw pump beed used to transfer bitumen, heavy oil etc, pump can bear 300 degree high temperature.
