Bantalan Rol Dorong Tirus

Our tapered thrust roller bearings are designed to accommodate heavy axial loads and peak loads. Tapered thrust roller bearings include rollers that have conical sections. The bearings are very stiff and require little axial space. Cage materials include steel, pressed steel cage, or machine brass cage.

Bantalan Rol Dorong Tirus

The inner and outer raceways of tapered thrust roller bearings are tapered, and the rolling elements are also tapered rollers. The extension lines of the three converge at the same point as the bearing line. Therefore, the movement friction is smaller than other thrust roller bearings. Tapered thrust roller bearings do not allow angular error between the shaft and the bearing seat.

Types of tapered thrust roller bearings

Taper thrust roller bearings enable axially very compact bearing arrangements to be produced, which can carry hefty axial loads, and are insensitive to shock loads. They make single and double-direction taper thrust roller bearings. They are used for rolling mill screw-down arrangements. The screw-down approaches constitute a unique design of single-direction taper thrust roller bearing and have a full complement of rollers.

single direction taper thrust roller bearings

We produce single-direction taper thrust roller bearings in two designs that differ in the execution of the washers.

Bearings of the one design (1) have a shaft and housing washers with the exact dimensions. These washers both have a tapered raceway and one retaining flange. The bearings have a cage that is centered on both washers. Bearings of this design are to be preferred where hefty axial loads occur, for example, in the swivels of drilling rigs or crane hooks.

Bearings of the other design (2) have a shaft washer with the tapered raceway and retaining flange, whereas the housing washer is a plane (flat). Therefore, bearings of this design can accept minor eccentricities of the shaft concerning the housing bore without any detrimental influence on bearing performance. Except for a few sizes with a full complement of rollers, the bearings are fitted with a roller-centered cage.

Double direction taper thrust roller bearings

Taper thrust roller bearings of the double direction type are mainly used together with multi-row cylindrical roller bearings in rolling mill applications. Those bearings with a plane shaft washer(3) are the more popular as they can accommodate slight eccentricities of the shaft concerning the housing bore, of the order of the radial internal clearance of the radial bearing with which they are used. A spacer sleeve is arranged between the two housing washers. This is dimensioned so that the cover screws of the chock can be fully tightened, and no unique spring adjustment of the bearing is required.

The double direction taper thrust roller bearings with tapered raceways on the shaft and housing washers (4) generally have a higher axial load-carrying capacity than the bearings with a plane shaft washer. They are also able to locate the shaft to a certain extent radially. Double-direction tapered roller thrust bearings are usually installed with a loose fit in the roll neck and housing, and most bearings have one or two locating grooves in the shaft washer. This prevents the shaft ring from disengaging.

Features of tapered thrust roller bearings

  • Desain terpisah
    The shaft and housing washers and the roller and cage thrust assemblies of tapered thrust roller bearings with cages can be mounted separately.
  • Gesekan rendah
    The flange's optimized roller end design and surface finish promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear.
  • Umur panjang
    Depending on the design, crowned or logarithmic raceway profiles optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment compared with conventional straight raceway profiles.
  • Keandalan operasional yang ditingkatkan
    The surface finish on the contact surfaces on the rollers and raceways supports the formation of a hydrodynamic lubricant film.
  • Kapasitas pengangkutan beban tinggi
    The rollers incorporated in tapered thrust roller bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution and enables the bearings to accommodate heavy axial loads.

Applications of tapered thrust roller bearings

Single-direction taper thrust roller bearings are suitable for hook and oil drilling rig rotation. Double direction taper thrust roller bearings are ideal for rolling mill roll necks.
