Angular contact ball bearing equivalent dynamic load and tolerance

Design and Safety Guidelines for Single Row Angular Contact Ball Bearings Equivalent Dynamic Load of Bearing Equivalent Dynamic Load of Bearing Equivalent Dynamic Load P is suitable for the case where the bearing is subjected to both radial and axial dynamic loads. The rated life of the bearing under the equivalent dynamic load P is the same as the bearing under the actual combined load. For bearings under dynamic load, the following formula is used: contact angle 4Fa kN bearing axial dynamic load Fr kN bearing radial dynamic load P kN bearing equivalent dynamic load under combined load. For bearings under dynamic load, the following formula is used: contact angle 3Fa kN bearing axial dynamic load Fr kN bearing radial dynamic load P kN bearing equivalent dynamic load under combined load. Minimum load Under continuous operating conditions, for angular contact ball bearings with cages, the minimum radial load must meet P/Cr 0.01. For the speed limit nG of the bearing, please refer to the dimension table. The running speed of the bearing cannot exceed the dynamic limit speed nG. The bearing arrangement load is greater than the bearing equivalent dynamic load for a single bearing P u003d Fr P u003d 0.35 · Fr + 0.57 · Fa The bearing arrangement load is greater than the bearing equivalent dynamic load for a single bearing P u003d Fr P u003d 0.39 · Fr + 0.76 · Fa The bearing arrangement is designed to make the bearing The performance is comprehensively utilized, and the adjacent structure must have an appropriate design. Shaft and housing bore tolerances For the recommended tolerances of cylindrical bores to bearing shafts, see the table on page 37. Refer to the table on page 38 for the recommended tolerances of the radial bearing housing holes. Mounting dimensions The bearing dimension table gives the maximum values u200bu200bof the lead angle radii ra and ra1 and the diameters Da, Db and da of the shoulders of the adjacent structure. The main dimensions of standard angular contact ball bearings with precision dimensions and geometric tolerances conform to the standard DIN 628-1. The size and geometric tolerance of the standard bearing is P5, which conforms to the standard DIN 620-2. According to the agreement, we can provide non-standard bearings with other tolerance levels.
