    Lotton thrust-aligning roller bearings and spherical roller bearings Similarly, race raceway is consistent with the bearing center axis as the center point of the sphere, such as spherical roller bearing type, therefore, with self-aligning function, concentricity and shaft deflection less sensitive.
    Product Features
    Lotton thrust spherical roller bearings and other thrust bearing different samples, such axial load bearing capacity is very large, the axial load can also withstand a plurality of radial load, but the radial load shall not exceed an axial load 55%.
    Just load P and P0 does not exceed 0.05C0, and the shaft ring rotates, the bearings allow listed in the following table aligning angle.
    Aligning bearing diameter series angular bearing diameter series aligning angle 200 Series 1 ° ~ 1.5 ° 300 Series 1.5 ° ~ 2 ° 400 Series 2 ° ~ 3 ° smaller values ​​apply to larger bearings, and allows the load is increased aligning angle will be reduced.
    The general use of oil lubrication.
    Lotton thrust-aligning roller bearings can withstand axial load, axial displacement to limit one-way bearing, it can be used as a one-way axial positioning. And thrust cylindrical roller bearings compared to bearing capacity, sliding a small, but a lower speed limit.

    Lotton thrust spherical roller bearing retainer
    Cage generally use solid brass frame and stamping frame. When using solid brass cage, cage code does not post signs, and the rest mark the corresponding post code.
    Lotton thrust-aligning roller bearings minimum axial load
    Lotton thrust spherical roller bearings work required minimum axial load,
    Famin (whichever is greater of the following two formulas obtained)
    Famin = C0a / 1000
    Famin = 1.8Fr + 1.33 (C0a / 2000) 2 ×
    Famin: required minimum axial load kN
    n: Speed
    C0a: Basic static load rating kN
    Fr: radial load kN
    Equivalent dynamic load
    P = Fa + 1.2Fr
    Equivalent static load
    P0 = Fa + 2.7Fr
    Lotton thrust spherical roller bearings use
    ThLotton bearings are mainly used in oil rig, the system iron steel machinery, hydroelectric power, vertical motors, marine propeller shafts, tower cranes, extruders.
    Bearing Features
    1, Lotton thrust spherical roller bearing outer ring and the bearing housing bore should not use an interference fit with the inner ring and the journal should not be too tight, requiring adjustment nut should be used in the installation can make it produce more flexible axial displacement. Because Lotton thrust spherical roller bearings if interference fit, easy to change the contact angle of the bearing, resulting in uneven distribution of bearing loads, cause high temperature. Therefore, this type of installation with the inner bearing journal and bearing outer ring and the housing bore, the general should be hands thumbs can just push the journal bearing and the housing bore for the best.
    2, for Lotton thrust spherical roller bearings mounted axial clearance, the adjusting nut on the journal available, adjustment shims and bearing hole threads, or other methods spring preload adjustment. The size of the axial clearance, and bearing mounting arrangement when material from the bearing shaft and bearing between related, can be determined according to the working conditions. For high-load high-speed self-aligning roller bearings, when adjusting the clearance, must consider the impact of temperature on the axial clearance, will reduce the amount of clearance to estimate the temperature rise due account, that is, the axial travel To properly adjust the gap a little too big. For low speeds and withstand vibration bearings, should take no clearance installation, or preloaded installation. Its purpose is to make spherical roller bearings and roller raceway produce good contact load is evenly distributed, preventing rollers and raceways damaged by shock and vibration. After the adjustment, the size of the axial clearance with dial gauge testing. The method is first dial gauge fixed in the body or bearing housing, so that the dial gauge contacts against the smooth surface of the shaft, the shaft axially pushed around, is the biggest swing of the hands of the axial clearance value.
