Double Row Tapered Roller Bearings

We manufactures double row tapered roller bearings in the TDO and TDI designs, in many variants and with different features. Depending on the design, these bearings can accommodate heavy radial loads, axial loads in both directions and have a high degree of stiffness. You can get double row metric and inch size tapered roller bearings here.

Features of Double row tapered roller bearings

  • High load carrying capacity
    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 size of the contact angle, which is 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
    Double row tapered roller bearings locate the shaft in both directions with a specific axial clearance or preload.
  • High stiffness
    Double row tapered roller bearings provide a stiff bearing arrangement.
  • Low friction
    The optimized roller end design and surface finish on the flange 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 of 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
    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 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.
