Cylindrical Roller Bearings are bearings where cylindrical rollers are used as the rolling elements as opposed to balls.

Cylindrical roller bearings have a greater line of contact area with the outer ring and therefore distribute loads across a broader surface. Subsequently, they have a relatively high radial load capacity but are also very suitable for high speeds. Depending on the series as a number of cylindrical roller bearings have no ribs on either or both of the inner or outer rings, so the rings can move axially relative to each other which means they can be used as free-end bearings.

A number of cage styles are available to accommodate the vast range of applications thus providing a wide choice of speeds and loads. Polyamide, pressed steel and brass cages are all readily available. A full compliment variation is also available where higher loads and lower speeds are designated. For precision machine tools there are also an extensive range of double row cylindrical roller bearings that offer greater stability and high radial rigidity.

Typical designations for the cylindrical roller bearing are listed below to aid identification but our knowledgeable staff are always available if further assistance is required.

N Series - Bearings of N design are single row cylindrical roller bearing and have two fixed ribs on the inner ring that retain the rollers and cage and one smooth outer ring.    This design allows an axial displacement in certain limits, of the shaft in relation to the housing. N Series rolling bearings are used in non-locating bearing units and have virtually no thrust capacity.

NU Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and one smooth inner ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. NU Series rolling bearings are used in non-locating bearing units and have no virtually thrust capacity.

NJ Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and a fixed rib on the inner ring which can guide the shaft axially in a single direction 

NUP Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and, on the inner ring, a fixed rib and a support washer. They can be used as locating bearings, guiding the shaft axially in both directions.

RNU Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and has no inner ring. Instead, it uses the shaft as the opposing raceway.

NF Series - Also able to carry incidental thrust loads, this bearing type features two integral ribs on the inner ring and a single rib on the outer ring.

NN Series - Bearings of NN design are double row cylindrical roller bearing and have three fixed ribs on the inner ring that retain the rollers and cage and one smooth outer ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. NN Series rolling bearings are used in non-locating bearing units and they have no virtually thrust capacity.

NNU Series - Are double row cylindrical roller bearings and have three fixed ribs on the outer ring and one smooth inner ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. NU Series rolling bearings are used in non-locating bearing units and they have no virtually thrust capacity.
