Single row cylindrical roller bearings

 

The rollers in a single row cylindrical roller bearing are always guided between the integral "open" flanges on one of the rings. These "open" flanges combined with the specially designed and surface treated roller ends, provide improved lubrication, reduced friction and consequently lower operating temperature.

The ring with the integral flanges together with the cylindrical roller and cage assembly can be separated from the other ring. This results in easy mounting and dismounting, particularly where the load conditions are such that interference fits are required for both rings.

 

Tolerances

 

 single row cylindrical roller bearings are manufactured to Normaltolerances for dimensional accuracy and to p6tolerances for running accuracy as standard. Some bearings, particularly those of the narrow series 18, 19 and 10, are also available with higher accuracy to tolerance class P6

The tolerances are in accordance with ISO 492:2002

 

Minimum load

 

To achieve satisfactory operation, single row cylindrical roller bearings, like all ball and roller bearings, must always be subjected to a given minimum load, particularly if they are to operate at high speeds or are subjected to high accelerations or rapid changes in the direction of load. Under such conditions, the inertia forces of the rollers and cage, and the friction in the lubricant, can have a detrimental influence on the rolling conditions in the bearing arrangement and may cause damaging sliding movements to occur between the rollers and raceways.

The requisite minimum load to be applied to single row cylindrical roller bearings can be estimated using where 

Frm = minimum radial load [kN]
kr = minimum load factor (see product data)
n = rotational speed [r/min]
nr = reference speed [r/min] (see product data)
dm = mean diameter of bearing 
= 0,5 (d + D) [mm]
