Cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, double row bearings, multi-row bearings, single, double and multi-row full complement bearings (without a cage) and split bearings complete the international standard assortment provided here.
Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds. Full complement bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. CHG high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with a cage.
1. Cylindrical roller bearings feature high radial load because the rollers and raceway are in linear contact
2. The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft axial movement, to a certain extent, relative to the housing position
3. The NJ and NF types carry a certain degree of axial displacement in both directions so they are also use
d as free side bearings
4. Models available: NU, NG, NUP, N, NF, NH, NNU, NIV
