The roller of the cylindrical roller bearing is in line contact with the raceway, so the bearing can bear heavier radial load.
Applications are found in situations characterizes by heavy load and shock load, and also by high-speed rotation.
These bearings are separable bearings, and convenient to be mounted and dismounted. They are designed as types of single,
double and multiple rows among which the single row cylindrical roller bearings are most applicable. Normally these bearings
can accommodate radial load only, none but single row bearings with ribs both on inner and outer rings can carry lighter constant
axial load.

Q4 - How to customize bearing(non-standard) from your company?
 A -We offer OEM,Customized(Non-standard) service and you need to provide drawing and detailed Technical Data.
Q5 -   What should I care before installation?
 A   - Normally, the preservative with which new bearings are coated before leaving the factory does not need to be
        removed; it is only necessary to wipe off the outside cylin­drical surface and bore, if the grease is not compatible
        with the preservative, it is necessary to wash and carefully dry the bearing.
      -Bearings should be installed in a dry, dust-free room away from metal working or other machines producing
        swarf and dust.
Q6 - How to stock and maintenance my bearings right? 
 A   - Do not store bearings directly on concrete floors, where water can condense and collect on the bearing;
      -Store the bearings on a pallet or shelf, in an area where the bearings will not be subjected to high humidity
       or sudden and severe temperature changes that may result in condensation forming;
      -Always put oiled paper or, if not available, plastic sheets between rollers and cup races of tapered roller bearings.

The spectacle blind is a kind of pipe parts, mainly for the convenience of maintenance. You can paint the upper half of "8" black to know the specific shape. It's half blind, half iron. It is commonly used for the pipeline flange that needs to change the process. The material mainly includes carbon steel, stainless steel and alloy. It can be selected according to the pipeline pressure grade and pipeline medium. The meaning of use is usually used on pipelines with large pipe diameter. Usually, one end of the flange is used to occupy the space to keep the pipeline unblocked. If necessary, the blind plate with the same thickness at the other end is used to cut off the pipeline. Avoid the forced expansion of pipeline caused by temporary replacement of other blind plates, which will affect the whole system.
