High Precision Full Complement Roller Bearings C4 Long Service Life
Cylindrical Roller Bearings
Cylindrical roller bearings are commonly separable and easy to mount and dismount. They can be divided into single row, double row and multi-row cylindrical roller bearings. The widely used bearings are cylindrical roller bearings with cage. Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used. There are single or double row bearings with a full complement of rollers and other bearing arrangements. Cylindrical roller bearings have high radial load carrying capacity and are also suitable for high speeds
Features
Cylindrical rollers have linear contact with the raceway, and the bearings can carry heavier radial load. Cylindrical bearing applications are found in situations characterized by heavy load and shock load and also high rotation speed. The N type and NU type bearings can be movable along the shaft. They can adapt to the position changes between the shaft and housing caused by the thermal expansion or the mounting error and are most suitable for free end shafts. NJ and NF types can accept certain axial load in one direction, and NH and NUP types can accept certain axial load in two directions. Inner ring and outer ring can be separable, so they are convenient to mount and dismount.
Applications
These bearings are mostly found in middle-sized and large-sized motors, electricity generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, unloading and lifting machines and other industrial machines.
Concerning single row cylindrical roller bearing, N,NU,NJ,NF,NUP,RN,RNU series are also offered.
