Low friction between rolling body and ring retaining edge, suitable for high speed rotation.
According to whether the ring has a side, the bearings can be divided into NU, NJ, NUP, N, NF and other single-row bearings, and NNU, NN and other double-row bearings.
The bearing is a detachable structure with inner and outer rings.
Cylindrical roller bearings with inner ring or outer ring without flank, the inner ring and outer ring can move relative to each other in axial direction, so they can be used as free end bearings.
One side of the inner ring and the outer ring has a double flank, and the other side of the ring has a single flank cylindrical roller bearing, which can bear a certain degree of axial load.
The cage is usually made of steel plate or copper alloy car.
But some use polyamide forming cages.
To use:
The four-row cylindrical roller bearing mainly bears radial combined load in diameter and axis.
Bearing capacity depends on the raceway Angle of the outer ring, the greater the Angle, the greater the bearing capacity.
This kind of bearing belongs to separate type bearing, which can be divided into single row, double row and four row tapered roller bearings according to the number of rolling body in the bearing.
Clearance of single row tapered roller bearing shall be adjusted by the user during installation;
The clearance of double-row and four-row tapered roller bearings has been given according to the customer's requirements when the product leaves the factory, and it does not need to be adjusted by the customer.
Four row cylindrical roller bearings have conical inner ring and outer ring raceway, conical roller arranged between the two.
All projection lines on the conical surface meet at the same point on the bearing axis.
This design makes tapered roller bearings particularly suitable for bearing combined (radial and axial) loads.
The axial load capacity of the bearing is mostly determined by the contact Angle a.
The greater the alpha Angle, the higher the axial load capacity.
The Angle is expressed by the calculation coefficient e;
The larger the e value, the larger the contact Angle, the greater the applicability of bearing bearing axial load.
The four-row cylindrical roller bearings are usually separable, that is, the conical inner ring consisting of the inner ring of the roller and retainer assembly may be mounted separately from the conical outer ring (outer ring).
Four-row cylindrical roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
