Cylindrical roller bearing

Quick introduction: The internal structure of Cylindrical Roller Bearing adopts the rollers 90 ° perpendicular cross arrangement, equipped with spacing cage or spacers between the rollers, which can prevent mutual friction or tilt between the rollers, effectively preventing the increased rotational torque.

Features: 

1. Radial load capacity, suitable to withstand heavy load and shock load.
2. The friction coefficient is small, suitable for high speed, speed limit near the deep groove ball bearings.
3. N type and NU type can move axially, able to adapt the relative position change caused by thermal expansion or installation error of shaft and housing, can be used for supporting the free end.
4. have a higher request on shaft or housing bore machining, the relative deflection of outer ring axia should be strictly controlled after installation to avoid contact stress concentration.
5. The inner or outer ring separable, easy installation and removal.

Structure:

single row: N ourter ring unflanged, inner ring both sides flanged.

                NU outer ring two sides flanged, inner ring unflanged.

                NF outer ring one side flanged, inner ring both sides flanged.

                NJ outer ring two sides flanged, inner ring one side flanged.

                NUP outer ring two sides flanged, inner ring one certain side flanged, the other side has loose rib.

                NFP outer ring one certain side flanged, the other side has loose rib, inner ring two sides flanged.

                NH  NJ bearing + HJ separate thrust collar

double row: NN outer ring unflanged, inner ring both sides flanged, also flanged in the middle.

                 NNU outer ring both sides flanged, also flanged in the middle, inner ring unflanged.

                 NNF full complement & double rows, composed by one middle flanged outer ring + two both sides flanged inner ring.

four row: FC, composed by two outer rings and one inner ring, two outer rings both sides flanged, and middle flanged, inner   ring unflanged.

             FCD, composed by two NN type.

*Four row cylindrical roller bearings are mainly used in the cold, the hot rolling mill, billet and other rolling mill machinery, bearings for the separation of structure, bearing rings and the rolling element can be easily separated, and therefore, the bearing cleaning, inspection or installation disassembly are very convenient

Application: Medium-sized motors, locomotives, machine tool spindle, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen and lifting transportation machinery.
