Single-row full-complement cylindrical roller bearings are suitable for arrangements with a large radial load and lower speeds compared to cylindrical roller bearings with a cage. Full-complement cylindrical roller bearings have the largest possible number of rollers and are without a cage. Additional designation V. Single-row full-complement cylindrical roller bearings are manufactured in two designs.

NCF Design

The inner ring of the bearing has guiding flanges on both sides. The outer ring has one guiding flange. The NCF design bearing is axially guiding in one direction. The bearing accommodates axial load in one direction and accommodates axial displacement of the shaft relative to the housing in the opposite direction. The outer ring has a retaining ring on the side without the guiding flange, which secures the components in the mounted state. The NCF design corresponds to the SL1818, SL1819, SL1830 and SL1822 designs of INA bearings.

NJG Design

The outer ring of the bearing has guiding flanges on both sides. The inner ring has one guiding flange. The NJG design bearing is axially guiding in one direction. The bearing accommodates axial load in one direction and accommodates axial displacement of the shaft relative to the housing in the opposite direction. The NJG bearing is a dismountable bearing. When the inner ring is removed, the rollers hold together with the outer ring due to the optimal alignment of the raceway diameter of the outer ring and the diameter and number of rollers. The NJG design bearings belong to the heavy 23 dimension series. The NJG design corresponds to the SL1923 design of INA bearings.

Boundary dimensions

The boundary dimensions of single-row full-complement cylindrical roller bearings given in the dimension tables comply with the ISO 15 international dimension plan.

Precision

Single-row full-complement cylindrical roller bearings are normally manufactured with the normal precision grade P0, which is not designated. Limiting values for dimensional and running accuracy deviations are given in ISO 492.

Designation

The designation of bearings with the basic design is given in the dimension tables. The difference from the basic design is designated by additional marks according to STN 02 4608. The table section also contains the designation of the INA design with matches for individual bearings.

Radial Clearance

Single-row full-complement cylindrical roller bearings are manufactured with a normal radial clearance, which is not designated. Bearings with reduced (C2) or increased (C3, C4, C5) radial clearance are available for special arrangements. The values of radial clearance comply with ISO 5753-1 and are valid for bearings in the unmounted state.

Permissible Misalignment

The permissible misalignment of single-row full-complement cylindrical roller bearings is subject to the same conditions as standard single-row cylindrical roller bearings with a cage (see the Single-row Cylindrical Roller Bearings chapter).

Operating Temperatures

For arrangements with an operating temperature higher than 120°C, bearings are supplied with specially heat-treated components, which ensure dimensional and shape stability even with long-term exposure to higher temperatures from 150°C to 400°C (S0, S1, S2, S3, S4). The supply of stabilised bearings needs to be negotiated in advance with the supplier.

Minimum Load

For single-row full-complement cylindrical roller bearings, a minimum radial load corresponding to 4% of the basic dynamic bearing capacity is recommended. Cylindrical roller bearings work reliably when axial loads are applied if the bearings are radially loaded at the same time. The Fa/Fr ≤ 0.5 ratio must be observed.

Dynamic and Static Equivalent Bearing Load

Dynamic Equivalent Bearing Load

If full-complement cylindrical roller bearings are used exclusively with a radial load without axial forces, the dynamic load is calculated as follows:

Pr = Fr

If the bearings are also used to accommodate axial forces, the dynamic loads are calculated as follows:

Where:
e = calculation coefficient
e = 0.2 for NCF series bearings (18)
e = 0.3 for NCF (22, 29, 30) and NJG (23) series bearings

Y = axial load coefficient
Y = 0.6 for NCF series bearings (18)
Y = 0.4 for NCF (22, 29, 30) and NJG (23) series bearings

Static Equivalent Bearing Load

The following applies to statically loaded cylindrical roller bearings:

P0r = Fr
