Cylindrical Roller Bearings (NU,N Series)

Since the rolling elements in cylindrical roller bearings make line contact with raceways, these bearings can accommodate heavy radial loads. The rollers are guided by ribs on either the inner or outer ring, therefore these bearings are also suitable for high speed applications. Furthermore, cylindrical roller bearings are separable, and relatively easy to install and disassemble even when interference fits are required. Among the various types of cylindrical roller bearings, Type E has a high load capacity and its boundary dimensions are identical to standard type. HT type has a large axial load capacity, and HL type provides extended wear life in conditions where the development of a lubricating film inside the bearing is difficult. Double and multiple row bearing arrangements are also avaible. For extremely heavy load application, the non-separable full complement SL type bearing offers special advantages. NU type outer rings have double ribs; outer ring and roller as well as cage can be separated from inner ring. N type inner ring have double ribs; inner ring and roller as well as cage can be separated from outer rings. Unable to accommodate even the lightest axial loads. This type is extremely suitable for and widely used as , the floating side bearings.
