FAG Single Row Tapered Roller Bearing Features Tapered roller bearings consist of solid inner and outer rings with tapered raceways and tapered roller assemblies using stamped steel cages. Bearings are separable. Therefore, the inner and outer rings with the roller and cage assembly can be installed separately. In addition to standard-size and standard-labeled bearings, there are also special metric and imperial bearings. The non-standard bearing designations are Z-5 or F-8. In the new design, please choose metric tapered roller bearings.
Radial and axial load carrying capacity Tapered roller bearings can withstand uniaxial and high radial loads. Usually two tapered roller bearings are paired using a symmetrical arrangement. Contact angle The axial load-carrying capacity depends on the contact angle; that is, the greater the contact angle, the greater the axial load the bearing can withstand. The coefficient e in the dimension table shows the bearing contact angle and the bearing capacity. The improved contact line between the angular misalignment tapered roller and the inner and outer ring raceways optimizes the stress distribution at the contact point, prevents edge stress and allows bearing misalignment. When the load ratio is P/Cr ? 0.2, the relative tilt angle of the inner and outer rings of the bearing must not exceed 4 points. If you need to bear more load or more tilt angle, please contact Qingdao Ruijing Mechanical and Electrical Equipment Co., Ltd. Sealed standard tapered roller bearings are non-hermetic.
Lubricated bearings can be lubricated with oil or grease. Operating temperature Single row tapered roller bearings are suitable for operating temperatures ranging from –30 °C to +120 °C. If the continuous operating temperature is +120 °C, please contact us Qingdao Ruijing Mechanical and Electrical Equipment Co., Ltd. The dimensionally stable temperature with an outside diameter greater than 240 mm is +200 °C.
Single-row tapered roller bearing cages Single-row tapered roller bearings use stamped steel cages. Since the cage has a certain amount of protrusion, the mounting dimensions and the amount of cage protrusion in the dimension table must be noted on page 111. Suffixes of existing designs, see table. Current Design Design and Safety Guidelines Equivalent Dynamic Load Equivalent Dynamic load P is suitable for radial and axial loads. It is consistent with the calculated life of the bearing under the action of the composite load in the actual process. Bearings subjected to dynamic loads use the following formula: Single-row bearings under dynamic load Fa kN Bearings Axial dynamic load Fr kN Bearing radial dynamic load e, Y – Coefficient, see equivalent dynamic load under dimension table P kN composite load. A suffix improved design described internal design standard external dimensions conform to international standards X P5 higher precision than the specific design loads Equivalent dynamic bearing load P = FrP = 0.4 · Fr + Y · Fa equivalent static load equivalent static load P0 suitable to withstand radial And axial load. The stress caused by the center point of the area where the force is greatest between the rolling element and the raceway contact surface is equal to the stress caused by the actual load synthesis.
For single bearings under static load, use: Single bearing under static load F0a kN Bearing axial static load F0r kN Bearing radial static load Y0 – Parameter, see Dimensional tables P0 kN Equivalent static bearing load under combined load. The minimum load is to ensure that the bearing does not slip during operation, and the bearing bears at least one minimum radial load Fr min in the radial direction. This is especially important for high speed, high acceleration conditions. In continuous operating conditions, the minimum radial load of a roller bearing with a cage must meet P/Cr 0.02.
The speed that affects the bearing's limit speed is the bearing itself. The limit speed nG cannot be exceeded, see the dimension table. Only the peripheral structure design is reasonable for the bearing pairing design, and the bearing can give full play to its performance. Shaft and housing tolerances For cylindrical bore radial bearings, the recommended shaft tolerances are listed on page 37, table. Recommended bearing tolerances for radial bearings, see table on page 38. The dimensions of the chamfering radii ra and rb of adjacent parts and the diameters of the shoulders of adjacent structures are given in the dimensions of the mounting dimensions. The retainer cage protrudes slightly to the side. In order to prevent scratching of the cage, the lateral minimum dimensions Ca and Cb in the dimension table must be taken into consideration in the design of the adjacent structure.
