FAG Thrust Cylindrical Roller Bearing Features Thrust cylindrical roller bearings have a small axial section height, high load capacity and high stiffness. One-way thrust cylindrical roller bearings consist of thrust cylindrical rollers and cage assemblies, a seat washer centered by the bearing seat, and a shaft washer centered by the shaft. The inner and outer diameters of the bearings and the running surfaces of the shaft and raceway are all finished. Bearings can withstand unidirectional axial force. Bearings 810 and 811 are single row bearings and conform to standard DIN 722/ISO 104. Angular contact ball bearings Z-5 and F-8 are special series, there is no standard size and designation. Operating Temperature Axial cylindrical roller bearing and thrust cylindrical roller cage assemblies have an operating temperature range of 30°C to +150°C. Cages Such bearings usually use brass cages. In series 810 and 811 the suffix is u200bu200bM. By negotiation we can provide cage design information for special bearings. Suffix Meaning Suffixes for existing standard bearing designs, see table. Existing Designs 1) Specially designed non-standard (Z-5, F-8) bearing sizes are available by agreement.

Equivalent dynamic load of bearing For bearings under dynamic load, the following formula is used: P kN equivalent dynamic load of bearing Fa kN axial dynamic load of bearing. Bearing equivalent static load For the bearing bearing static load, the following formula is used: P0 kN bearing equivalent static load 0a kN bearing axial static load. Minimum axial load To ensure reliable operation of the bearing, the minimum axial load Fa min must be calculated according to the following formula: Fa min N Minimum axial load C0a N (see dimension table) Basic static load rating ka Factor for determining the minimum load, see Table n min1 speed.

The entire face of the adjacent component design thrust bearing washers must be fully supported. Adjacent shoulders must be rigid, flat and perpendicular to the axis of rotation. Shaft and Housing Tolerances Shaft and Housing Tolerances: See Table. Orientation of shaft and housing hole tolerance washers Thrust bearing washers are installed with their raceways facing the rolling elements. For races, the raceway surface is the side with the smaller chamfer on the outside diameter. For shaft washers, the raceway surface is the side of the bore with the smaller chamfer. Accuracy Dimensional and Geometrical Tolerances The dimensional and geometrical tolerances of thrust bearing washers GS and WS are P5 or higher in accordance with DIN 620, see dimension table.
