cylindrical roller bearing

Nu type and N type allow the shaft to move axially relative to the shell within a certain range, so they are suitable for free end bearing.

NJ type and NF type can bear a certain degree of unidirectional axial load.

NUP type and NFP type can bear axial movement in two directions to a certain extent, so they are suitable for free end bearing.

Double row cylindrical roller bearing

Double row cylindrical roller bearings are divided into two types: cylindrical bore and conical bore.

In addition, there are bearings with oil holes and oil grooves in the outer ring.

Most of these bearings are used in machine tool spindle, but they can also be used in other occasions.

Four row cylindrical roller bearing

Four row cylindrical roller bearing can bear large radial load and impact load. It has high machining accuracy and is suitable for high speed. Most of them are used in rolling mill roll, but they can also be used in other occasions.
