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 -Â Â 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 cylinÂdrical 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?Â
 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.
