    Lotton tapered roller bearings are separable bearings, the bearing outer ring has a tapered raceway. This kind of bearing according to the number of columns loaded roller into single row, double row and four row tapered roller bearings Lotton different structural types. Lotton single row tapered roller bearings can bear radial load and axial load in one direction. When the bearing radial load, will produce an axial force component, so when you need another can withstand the axial force in the opposite direction of the bearing to be balanced.
    Definitions
    Ability Lotton single row tapered roller bearing axial load depends on the contact angle, the outer ring raceway angle, the greater the angle, the greater the axial load capacity. Lotton tapered roller bearings are used in an amount up to the Lotton single row tapered roller bearings. In the car's front wheels, the small size of the Lotton spend a double row tapered roller bearings. Lotton four tapered roller bearings used in large-scale cold rolling mill and other heavy machines.
    Structural features
    Lotton tapered roller bearing type code 30000, Lotton tapered roller bearings for the separation of bearings. Under normal circumstances, Lotton cone inside, especially in GB / T307.1-94 "Rolling bearings tolerance" are involved in the size range of roll is one hundred percent can be used interchangeably between universal child bearing outer ring and inner components .
    The angle of the outer ring and the outer raceway diameter has been standardized with the same dimensions specified. Not allowed to change the design and manufacturing time. Between the outer and inner components to cause Lotton tapered roller bearings are interchangeable common worldwide.
    Lotton Tapered roller bearings are mainly used to bear radial load mainly radial and axial load. Compared with the angular contact ball bearings, bearing capacity, low speed limit. Lotton Tapered roller bearings can withstand axial load in one direction, a direction to limit the axial displacement of shaft or housing.
    Classification
    Lotton single row tapered roller bearings have an outer ring, the inner ring and a set of tapered roller cover from the box-type cage into an inner component. Outer and inner components separated according to ISO tapered roller bearings standard dimensions, any one standard model of Lotton tapered roller bearing outer or inner components and the same model should be able to outer or inner components to achieve international swap. That same model except that the Department of outer dimensions, tolerances must comply with ISO492 (GB307) provided, the inner components of the cone angle, cone diameter components must also comply with the relevant provisions interchangeable.
    Typically, Lotton single row tapered roller bearing outer ring raceway of the cone angle between 10 ° ~ 19 °, able to withstand the combined effects of axial and radial loads. The larger cone angle, the axial load bearing capacity is also greater. Large cone angle of the bearing, post code plus B, cone angle between 25 ° ~ 29 °, it can withstand greater axial load. In addition, Lotton single row tapered roller bearings can be resized clearance during installation.
    Lotton double row tapered roller bearing outer ring (or inner) as a whole. Two inner (or outer) face similar small, middle spacer, clearance by the spacer to adjust the thickness of the spacer can also be used to adjust the thickness Lotton double row tapered roller bearings preloaded.
    Lotton four-row tapered roller bearings, such bearings Lotton performance and double row tapered roller bearing is basically the same, but more than Lotton double row tapered roller bearings to withstand greater radial load, lower speed limits, mainly for heavy machinery.
    Multi-sealing double, Lotton four tapered roller bearings, Lotton offers long life, multi sealed double, Lotton four tapered roller bearings. Personalize bearing the new design, fully sealed bearings change traditional design method, using the new structure type seal and dust seal combination, to improve the sealing effect, improve sealing performance. Multi-sealing double, Lotton four-row tapered roller bearings compared with open structure bearing, life expectancy increased from 20% to 40%; lubricant consumption reduced by 80%.
    Use
    Lotton Tapered roller bearings are mainly exposed to the radial diameter, axial load. Bearings carrying capacity depends on the outer ring raceway angle, the angle the greater the bearing
     The greater carrying capacity. This kind of bearing is a separate type of bearings, according to the number of columns bearing rolling elements are divided into separate, Lotton double row and four-row tapered roller bearings. Lotton single row tapered roller bearing clearance to be adjusted during installation; Lotton E double row and four row tapered roller bearing clearance in the factory based on user requirements for a given, not to be user adjusted.
    Lotton Tapered roller bearings have tapered inner and outer ring raceways, tapered roller arranged between the two. All conical surface projection lines in the bearing axis with a little together. Lotton This design makes tapered roller bearings particularly suitable for bear compound (radial and axial) loads. Most of the axial load bearing capacity is determined by the contact angle α; α angle the greater the axial load capacity is higher. Angle size to calculate the coefficient of e said; e larger the value, the greater the contact angle, the bearing axial load greater applicability.
    Lotton Tapered roller bearings are usually separated type, that is with roller and cage assembly of inner components can be tapered conical cup (outer ring) installed separately.
    Lotton Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics machinery and other industries.
    Installation
    The following information is provided by the quick and easy optimization Daquan automatic selection.
    Adjust the axial clearance of tapered roller bearings for Lotton installation 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 Lotton tapered 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 enable Lotton tapered 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.
    Lotton four tapered roller bearing installation (roller bearings):
    A, Lotton four-row tapered roller bearing inner ring and the roll neck with generally band gap, the first bearing into the bearing box during installation, and then loaded journal bearing box.
    Two, Lotton four tapered roller bearing outer ring and bearing housing bore also uses moving with, the first outer ring A load bearing box. The factory in the outer ring, the inner ring and the inner and outer spacer are printed with the word {HotTag} character symbols, character symbols must be the order of sequentially load bearing box during installation. It can not be arbitrarily interchanged to prevent changing the bearing clearance.
    Third, after all the parts are loaded into the bearing housing, the inner ring and the inner cage, outer ring and the outer spacer axial try to be.
    Fourth, the outer end face of the measurement gap width between the bearing cover plates to determine the thickness of the respective gasket.
    Multi-sealed bearings with post-code XRS flag.
