  • Tapered Roller Bearings Lm603049 Lm603011 451349dw 310 310cd Ee755280 755361cd - China

    The inner and outer ring raceways are segments of cones and the rollers are also made with a taper

    so that the conical surfaces of the raceways and the roller axes if projected,

    would all meet at a common point on the main axis of the bearing.

    This conical geometry is used as it gives a larger contact patch, which permits greater loads to be carried than

    with spherical (ball) bearings, while the geometry means that the tangential speeds of the surfaces of each of the rollers are

    the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs.

    When a roller slides rather than rolls, it can generate wear at the roller-to-race interface, i.e.

    the differences in surface speeds creates a scrubbing action.

    Wear will degenerate the close tolerances normally held in the bearing and can lead to other problems.

    Much closer to pure rolling can be achieved in a tapered roller bearing and this avoids rapid wear.

    The rollers are guided by a flange on the inner ring.

    This stops the rollers from sliding out at high speed due to their momentum.

    The larger the half angles of these cones the larger the axial force that the bearing can sustain.

    Tapered roller bearings are separable and have the following components: outer ring, inner ring, and roller assembly

    (containing the rollers and a cage).

    The non-separable inner ring and roller assembly is called the cone, and the outer ring is called the cup.

    Internal clearance is established during mounting by the axial position of the cone relative to the cup.

    The main purpose of such bearings: automotive front, rear, transmission, differential, pinion shaft, spindle,

    construction machinery, large-scale agricultural machinery, railway vehicles,

    gear reduction rolling mill roll neck small deceleration devices.

    Single-Row Tapered Roller Bearings

    The most basic and widely used tapered bearing, the single-row type consists of the cone assembly and the cup.

    It is usually fitted as one of an opposing pair. During equipment assembly, single-row bearings can be set to

    the required clearance or preload condition to optimize performance.

    Double-Row Tapered Roller Bearings

    Double- or two-row tapered roller bearings feature double cups and two single cones.

    They are available in a variety of configurations for general industrial and automotive applications.

    Four-Row Tapered Roller Bearings

    Four-row bearings combine the inherent high-load, radial/thrust capacity and direct/indirect mounting variables

    of tapered roller bearings into assemblies of maximum load rating in minimum space.
