Bearings • Roller Bearings • Spherical Roller Bearings

Spherical roller bearings employ rolling elements that are thick in the middle and thinner at the ends, with a race shaped to match. As a result, they are better suited to adjust to and support high radial loads and moderate axial loads, even when they are misaligned. One slight variation is the spherical roller thrust bearing, which is used specifically to support axial loads (e.g., vertical shafts). The elements can be spherical, conical, or cylindrical in shape; and for particularly heavy loads or where low friction is important, non-rolling elements can be employed, as well (e.g., hydrostatic, magnetic). Although these designs come with many advantages over traditional ball bearings, they are more expensive and produce higher friction, sometimes resulting in shorter operational life.

Compared with other thrust roller bearings, it is of a small friction coefficient, high speed and self-aligning.

  • Turbo Bearings

    Turbo Bearings is a manufacturer of spherical roller thrust bearings and double row spherical roller bearings. Offerings also include tapered roller bearings, double row tapered roller bearings, cylindrical roller bearings, needle roller bearings, and thrust bearings.

  • KML Bearing & Equipment

    KML is a manufacturer of spherical plain bearings which have an inner ring with a sphered convex outside surface, and an outer ring with a correspondingly sphered concave inside surface. The design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be permitted at relatively slow sliding speeds.

  • QM Bearings & Power Transmission

    QM Bearings manufactures spherical roller bearings. These bearings can accommodate shaft sizes from 1 7/16" to 7" and most metric sizes, are built to order, have steel housings, are easily converted from fixed to floating in the field, have external covers for extra sealing protection, and have standard withdrawal holes on all piloted flange cartridges.

  • WD Bearing

    WD Ball & Roller Bearings is a manufacturer of spherical roller bearings. These bearings are designed for heavy loading capacity, can compensate for shaft deformation and non-centered error with symmetrical double row spherical rollers self-aligning in the groove of the outer ring.

  • SNR

    SNR Industry is a manufacturer of spherical roller bearings which can accommodate misalignment up to 0.5° and are particularly suitable for heavy mechanics and heavy-duty operation. They sustain very high radial loads and moderate axial loads, both at low rotating speeds.

  • Bajaj Bearings

    Bajaj Bearings is a manufacturer and supplier of spherical roller bearings. These spherical roller bearings are known for their heavy-duty features. They contain two rows of barrel-shaped rollers which can align themselves freely in the sphered outer ring raceway. This provides compensation for bearing seat misalignment and shaft deflection. Positive roller guidance is achieved by the integral inner ring lip. The spherical roller thrust bearings incorporate a maximum number of large diameter and extra long rollers. The high degree of roller raceway conformity ensures even load distribution and a high carrying capacity. Bajaj spherical roller bearings are manufactured according to standard tolerances. The clearance groups normal, C3, and C4 make up for the different operating mounting conditions.

  • Schaeffler Group

    Schaeffler Group manufactures spherical roller bearings which are double row, self-retaining units comprising solid outer rings with a concave raceway, and solid inner rings and barrel rollers with cages. The inner rings have tapered or cylindrical bores. Symmetrical barrel rollers align themselves to the outer concave ring raceway. As a result, misalignments of the bearing seats and shaft deflections are compensated.

  • Ixin Bearing

    IXIN is a manufacturer of spherical plain bearings which feature a long working life, come in a wide range with various structures, and are made with refined chrome steel.

  • Metalcraft Engg Co

    Metalcraft is a manufacturer of spherical roller bearings.  Most of these bearings are self-aligning. Each roller features a curved form at a right angle to the direction of rotation, conforming closely to the outer and inner raceways. This gives this bearing high radial load carrying capacity. Applications include rudder shafts and support rollers, crankshafts, heavy ship line shafts, grinding machines and rolling mills.

  • NKE

    NKE Bearings is a manufacturer of spherical roller thrust bearings which are separable single direction acting axial bearings. These bearings are able to accommodate misalignment, are suitable for high axial and some radial loads, and have relatively high speed ratings. Applications include heavy vertical shafts, injection molding machines, etc.

  • NSK

    NSK is a manufacturer of spherical roller bearings which are designed for high load capacity. Some types have pressed steel cages, some have machined brass cages, and some have especially high load capacity, feature low torque and have a high-strength cage.
