Spherical Roller Bearings of the Series 213

Special feature of this series: Main dimensions according to DIN 635-2. Spherical roller bearings of the series 213 are narrower than spherical roller bearings of series 223 with the same inner diameter and outer diameter. It results a lower weight as well as a higher limiting speed. They are more resilient than the bearings of the series 222 but not that resilient as the bearings of the series 223.

Bore design, either cylindrical or tapered (1:12)

Maximum permissible load capacity of the bearing based on the materials used and the geometric design.

Noise level of the bearing during operation.

Smooth-running bearings have low frictional resistance.

Resistance of the materials used in the bearing to water and other corrosive media.

Maximum permissible speed of the bearing.

Protection of the bearing from the ingress of foreign particles and liquids.

Highest ambient temperature at which the bearing can be used without restrictions

Lowest ambient temperature at which the bearing can be used without restrictions

The bearing clearance is the amount by which the two rings of a non-installed roller bearing can be displaced in relation to one another. There are different internal clearance classes. CN is "normal internal clearance" and is the best choice for many applications. C3, C4, ... indicates increased clearance. C2, C1, ... stands for reduced clearance.

Inner and outer ring material

Material of the rolling element (i.e. the balls or rollers)

Material of the cage (the cage holds the rolling elements in place)

Type of lubrication of the rolling bearing. Rolling bearings are usually either greased, oiled or dry.
