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.
