NNF 5014 ADA-2LSV full cylindrical roller bearing 5014

1. Cylindrical Roller Bearings introduction: 

2. Cylindrical Roller Bearings specification:

3. Cylindrical Roller Bearings usage:

1) Cylindrical roller bearings are widely used in automobile, electrical. (Home appliances, electric tools, fitness equipment, motors, medical devices, motorbikes, textile machines)

2) equipment, instrument, building machinery, rolling stock agricultural machinery and various specialized machineries.

4. Cylindrical Roller Bearings series:

The cylindrical roller is in the linear contact with the bearing race and has a large loading capacity, capable of carrying large and punching loads and applicable to high-speed rotation. Such bearing is in multiple varied structures including single-row, double-row and four-row ones and mainly applied to a wide range of motors, dynamos, combustion turbines, main shafts of machine tools, reducing gears, handling machineries and transporters; therein, the four-row cylindrical roller bearing is mainly applied to the rolling mill.

Types of cylindrical roller bearing

• 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. Therefore, N Series rolling bearings are used in non-locating bearing units. Also, the N Series bearings 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. Therefore, NU Series rolling bearings are used in non-locating bearing units. Also, the NU Series bearings 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 in a single direction (axially).
• 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. This way 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. Therefore, N Series rolling bearings are used in non-locating bearing units. Also, the NN Series bearings 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. Therefore, NU Series rolling bearings are used in non-locating bearing units. Also, the NNU Series bearings have no virtually thrust capacity.
