Cylindrical Roller Bearing
Double Row Full Complement Cylindrical Roller Bearing
A double row full complement cylindrical roller bearing is a kind of cylindrical roller bearing. Double row full complement cylindrical roller bearings are designed to withstand heavy loads. Under the same width, this kind of bearing has a very high load carrying capacity compared with the traditional bearing with a cage; the radial section is small and can save space, but the speed is relatively low. Our double row full complement cylindrical roller bearings incorporate a maximum number of rollers, as they are not equipped with a cage. You can get three open bearings (NNCL, NNCF, and NNC design) and NNF design sealed bearings.
As one of the cylindrical roller bearing manufacturers, suppliers, and exporters of mechanical products, We offer cylindrical roller bearing and many other products. Please get in touch with us for details.

Series of double row full complement cylindrical roller bearings
Popular types of Double row full complement cylindrical roller bearings:
- NNCL design (open)
- NNCF design (open)
- NNC design (open)
- NNF design sealed bearings
Features of double row full complement cylindrical roller bearings
- High load carrying capacity
Bearings without a cage incorporate a maximum number of rollers. Therefore, double row full complement cylindrical roller bearings are suitable for weighty radial loads because of their second row of rollers. - High stiffness
The increased number of rollers increases radial stiffness. - Long service life
Applications of double row full complement cylindrical roller bearings
Double row full complement cylindrical roller bearings can withstand large radial and axial loads and resist overturning moments. Therefore, the length is used as a fixed bearing. If the same several bearings are installed on a shaft, the outer ring can have different rotation speeds because the outer ring is narrower than the inner ring. To make the pulley easy to fix to the outer ring of the bearing, there are annular grooves on both ends of the outer ring that can be fitted with elastic retaining rings. This is somewhat suitable for the pulley mechanism.
Double row full complement cylindrical roller bearings are industry interchangeable with size numbered bearings and are used in such applications as accumulator sheaves, gearboxes, and walking beam furnace eccentrics.
