NTN Inner Dia 20 mm Cylindrical Roller Bearing Single Row NF204   Features Type of Product : Cylindrical Roller Bearing Single Row Inner Diameter : 20 mm Model No : NF204 Width : 14 mm     1.  Types, design features, and characteristics Cylindrical roller bearings can accommodate heavy radial loads due to the line contact formed between their rolling elements and raceways. These bearings are also suitable for high speed applications since the rollers are guided by either inner or outer ring ribs. Cylindrical roller bearings are separable, allowing them to be easily installed and disassembled even when interference fits are required.Among the various types of cylindrical roller bearings, E type and EA type have a high load capacity while maintaining standard boundary dimensions. HT type has a large axial load capacity, and HL type provides extended fatigue life in poor lubrication conditions. Multiple row bearing arrangements are also available.For extremely heavy load applications, the non-separable full complement SL type bearing offers special advantages. For SL type and four- row cylindrical roller bearings, see section “C. Special application bearings.”Table 1 shows the various types and characteristics of single row cylindrical roller bearings. Table 2 shows the characteristics of non-standard type cylindrical roller bearings. Table 1  Cylindrical roller bearing types and characteristics Type code Design  Characteristics NU type N type -NU type outer rings have two ribs. The outer ring, roller, and cage assembly can be separated from the inner ring. N type inner rings have two ribs. The inner ring, roller, and cage assembly can be separated from the outer ring.-Unable to accommodate any axial loading. -This is widely used as the floating side bearing in a fixed-float arrangement. NJ type NF type -NJ type has two ribs on the outer ring, a single rib on the inner ring; NF type has a single rib on the outer ring, and two ribs on the inner ring.-Can receive single direction axial loads. -When there is no distinction between the fixed side and floating side bearing, these types can be used as a pair in close proximity. NUP type NH type (NJ＋HJ) -NUP type has a collar ring attached to the ribless side of the inner ring; NH type is NJ type with an L type collar ring attached.

The basic load ratings listed in the dimension charts correspond to use of the standard cages listed in Table 3. The basic load ratings listed in the dimension tables are for standard configurations. These ratings can change when a different cage type and number of rolling elements is utilized. Note: 1. Within the same bearing series, cage type is constant regardless of the cylindrical roller bearing type (NJ, NUP, N, NF).2. For high speed and other special applications, machined cages can be manufactured when necessary. Consult NTN Engineering.3. Among EA type bearings that use resin cages as standard, certain varieties use pressed cages. Consult NTN Engineering.4. Although machined cages are the standard for two-row cylindrical roller bearings, resin cages may also be used in some of these bearings for machine tool applications.
