Description:

NNC4930V used in medium-sized motors, locomotives, machine tool spindle, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen and lifting transportation machinery.

NNC4930V Cylindrical roller and the raceway is in line contact bearings. Load capacity, mainly bear radial load. Rolling ring wall friction is small, suitable for high-speed rotation. According to ring without ribs, it can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing inner ring, outer ring separable structure.

NNC4930V No inner or outer wall of the cylindrical roller bearings, the inner and outer rings can be relative to the axial movement, so it can be used as a free end bearings. In an inner and outer side of a double-wall, the other side of the ring has a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy solid cage. But there are also part of the use of polyamide forming cage.

Types of Cylindrical Roller Bearing:

N series cylindrical roller bearing design The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.

NU series cylindrical roller bearing design The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.

NJ series cylindrical roller bearing design The outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction.

NF series cylindrical roller bearing design The outer ring has one integral flange and the inner ring two integral flanges.

NP series cylindrical roller bearing design  The outer ring has one integral flange and one non-integral flange in the form of a loose flange ring and the inner ring two integral flanges.

NUP series cylindrical roller bearing design The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.

RN series cylindrical roller bearing design No outer ring and the inner ring two integral flanges.
