Cylindrical Roller Bearing

Cylindrical roller bearings are designed to accommodate heavy radial loads, and only some of them can additionally accommodate light short-term axial loads. Cylindrical roller bearings are especially suitable for use in applications with heavy radial loads, high speeds, and where interference fits are required on both bearing rings.

Structures

Panding Bearing can supply cylindrical roller bearings in the numerical series:

Single row cylindrical roller baerings

Single row cylindrical roller baerings are munufactured in various constructive versions, according to the pisition of the ribs on the rings, the NU NJ N NUP designs are given in the below table.
  Single row cylindrical roller bearings can be supplied with a snap ring groove in the outer ring. These bearings can be axially located in the housing by a snap ring to save space and reduce installation time.

Double-row cylindrical roller bearings

Panding bearing mainly supply double-row cylindrical roller bearings in NN30 NN30K NNU49 NNU49K series.

Cylindrical roller bearings without cage - Full complement cylindrical roller bearings

Single row full complement cylindrical roller bearings with NCF and NJG design are used to locate the shaft axially in one direction and eventually to accommodate axial displacement of the shaft relative to the housing in the opposite direction.

Double row full complement cylindrical roller bearings NNCL, NNCF and NNC open design bearings, as well as sealed NNF design bearings, are non-separable and have an annular groove and three lubrication holes in the outer ring to facilitate lubrication. NNF design bearings have three additional lubrication holes in the inner ring.

Multi-row cylindrical roller bearings

Four-row cylindrical roller bearings for the rolling mills - FC FCD FCDP 4NNU Series

The other Multi-row cylindrical roller bearings also can be supplied, please contact us for the details.

Cage material

Generally, pressed steel cages are available for the small items. With the large size, silod machined steel or brass cages are used.

Application

Cylindrical roller bearings are mainly used in large size electric machines, machine tolls spindles, axle baoxes, diesel engine crankshaft, transmission cases, rolling mills and others.

Tolerance

Panding Bearing suplly cylindrical roller bearings with P0, P6, P5, and P4 precision grade asccording to the current standards.
