TDI Type Double-row Inch Size Tapered Roller Bearings

TDI Type double row inch size tapered roller bearings are a common type of tapered roller bearings. TDI Type double row inch tapered roller bearings consist of a single-piece (double) inner ring and two single outer rings. It is usually supplied complete with an outer-ring spacer as a pre-set assembly. TDI bearings can be used at fixed (locating) positions on rotating shaft applications. For revolving housing applications, the double inner ring of type TDI can be used to float on the stationary shaft.

Features of TDI Type double row tapered roller bearings

  • High load-carrying capacity
    TDI Type Double row tapered roller bearings are suitable for heavy radial and axial loads. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The contact angle size, usually between 10° and 30°, is related to the calculation factor e (from the product tables): the larger the value of e, the larger the contact angle.
  • Axial loads in both directions
    TDI Type Double row tapered roller bearings locate the shaft in both directions with a specific axial clearance or preload.
  • High stiffness
    TDI Type Double row tapered roller bearings provide a stiff bearing arrangement.
  • Low friction
    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. In addition, the bearings can better maintain preload and run at reduced noise levels.
  • Long service life
    The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles.
  • Enhanced operational reliability
    The optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
  • Consistency of roller profiles and sizes
    The rollers incorporated in our TDI Type double row tapered roller bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately.

Application of TDI Type double row tapered roller bearings

  • mining
  • petroleum
  • heavy machinery
  • wind power
  • engineering machinery
  • and other industries
