Cylindrical roller bearings, full-complement, two r.

Full-complement cylindrical roller bearings are specifically suitable for highly stressed bearing points with moderate speeds. These non-sealed bearings are preferably used in gearbox production.

In addition to very high radial forcers, the two-row cylindrical roller bearings NNCF….V do also accept axial forces in one direction. Thus they can also be used as step bearings.

Heat treatment
Full-complement cylindrical roller bearings have been heat treated so that they can be used up to an operating temperature of 150 °C. Bearings with an outer diameter over 120 mm maintain the accurate dimensions up to 200 °C.

Tolerances
The basic design of full-complement cylindrical roller bearings has the standard tolerance of radial bearings. Also other bearing tolerances are available on request.

Bearing clearance
The radial bearing clearance corresponds to the bearing clearance group CN in accordance with DIN 620-4. Other designs are possible on request.

Compensation of misalignment
The modified line contact between rollers and raceways of the cylindrical roller bearings prevents edge stresses and allows compensation of misalignment to a certain extent. The installation points of two-row cylindrical roller bearings must not be misaligned.
