NSK 539/800K Spherical Roller Bearing

Spherical roller bearings consist of a common spherical raceway outer ring and two rows of spherical rollers between the double raceway inner ring. The spherical roller bearings is self-aligning, and can automatically adjust the misalignment caused by the deflection or misalignment of the shaft or bearing seat, and the allowable alignment angle is 1~2.5 degrees. Spherical roller bearings can bear radial load, bidirectional axial load and its combined load, especially the radial load capacity is large, and it has good anti-vibration and impact resistance. It is widely used in iron and steel metallurgical equipment, mining equipment, cement machinery, paper machinery, ships, coal mills, petroleum machinery, engineering machinery, etc.

Product Description

SPHERICAL ROLLER BEARINGS

Spherical roller bearings consist of a common spherical raceway outer ring and two rows of spherical rollers between the double raceway inner ring. The spherical roller bearings is self-aligning, and can automatically adjust the misalignment caused by the deflection or misalignment of the shaft or bearing seat, and the allowable alignment angle is 1~2.5 degrees. Spherical roller bearings can bear radial load, bidirectional axial load and its combined load, especially the radial load capacity is large, and it has good anti-vibration and impact resistance. It is widely used in iron and steel metallurgical equipment, mining equipment, cement machinery, paper machinery, ships, coal mills, petroleum machinery, engineering machinery, etc.

 

 

 

Installation method:

The inner hole of the spherical roller bearing has two installation methods: cylindrical and conical, and the conical tapered hole is 1:12 and 1:30. By unloading the sleeve, the bearing can be installed on the optical shaft or stepped shaft conveniently and quickly. The cylindrical inner hole can also be installed on the tapered shaft with an inner taper sleeve.

 

 

 

Features: 

CA type self-aligning roller bearings, the inner ring has no middle ribs, and there are small ribs on both sides, equipped with symmetrical rollers, brass or cast iron cages.

 

 

 

Advantages: 

The cage of CA type spherical roller bearing is designed as an integral cage. In addition to bearing radial load, this type of bearing can also bear bidirectional axial load and its combined load. It has a large bearing capacity and has good resistance impact capability.

 

 

 

Most spherical roller bearings are designed with two rows of rollers, allowing them to take very heavy radial loads and heavy axial loads. There are also designs with one row of rollers, suitable for lower radial loads and virtually no axial load. These are also called "barrel roller bearings" or "Tonnenlager" and are typically available in the 202- and 203-series.

The internal design of the bearing is not standardised by ISO, so it varies between different manufacturers and different series. Some features that may or may not exist in different bearings are:

  • Lubrication features in inner or outer ring
  • Central flange
  • Guide ring or center ring
  • Integrated seals
  • Cage
