Except for RAA, all cylindrical roller bearings can precisely control the rollers during operation at various speeds. The inner or outer ring of this type of bearing is designed with precision ground dual edge flanges, which are mainly suitable for high radial load turbine engine spindles, transmission devices, and gearbox applications.
Size range: Outer diameter 22 mm to 300 mm (special design up to 600 mm available)
Design Features
RF and RJ structures are particularly suitable for applications that require axial positioning or unidirectional thrust.
For working environments with higher loads and speeds, RJ construction is particularly convenient for lubricating the inner ring through fuel injection holes.
RU and RN adopt a fully floating structure, allowing for some axial movement during operation. Among them, the advantage of RN is that when the high-speed operation load is small or the load is constantly changing, the rollers are less likely to slip or slide; The design of RU is beneficial for lubrication under heavy loads.
RUS and RNH bearings are designed as a whole, with rollers rolling directly on reinforced and ground shafts or bearing seats, and their performance characteristics are similar to RU and RN.
RAA has a single gear inner and outer ring, and the bearing has a high flange structure that can bear partial thrust in one direction, making it suitable for low-speed or oscillating working environments.
