Single-row full complement cylindrical roller bearings

Single-row full complement cylindrical roller bearings

Because the ring raceways are full of rollers and having no cage, the full complement cylindrical roller bearings have higher bearing capacity. At the same time, because this type of bearing has no cage to guide and separate the roller, there will be relative slippage between the rollers. So, compared with the ordinary cylindrical roller bearings, their using speed is lower and noise is lager. The main structures are: single row (NCF type) and double row (NNCF) bearings.

Product introduction

NCF type

NCF - it is single row roller bearing, can carry unidirectional axial load, and can be used as unidirectional positioning bearing;

NNCF type

NNCF - it is double row roller bearing, can carry unidirectional axial load, can be used as unidirectional positioning bearing, and is suitable for the low speed and heavy load conditions.

Open single row and double row full complement cylindrical roller bearings are mainly used for the low speed and heavy load conditions of general mechanical equipment.

Closed double row full complement cylindrical roller bearings are mainly used for wire rope pulley of crane.
