TDO Jenis Dua Baris Inci Saiz Tirus Galas Gelek

TDO Type double row inch size tapered roller bearings are a common type of tapered roller bearings. It has a one-piece (double) outer ring and two single inner rings. TDO Type double row inch tapered roller bearings are usually supplied with an inner-ring spacer as a pre-set assembly. This configuration gives a wide practical bearing spread and is frequently chosen for applications where overturning moments are a significant load component. TDO bearings can be used in fixed (locating) positions or allowed to float in the housing bore, for example, to compensate for shaft expansion. TDO CD outer rings also are available in most sizes. These outer rings have holes in the O.D. that permit the use of pins to prevent external ring rotation in the housing.

Features of TDO Type double row tapered roller bearings

• Kapasiti membawa beban yang tinggi
  TDO 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
  TDO Type Double row tapered roller bearings locate the shaft in both directions with a specific axial clearance or preload.
• Kekakuan yang tinggi
  TDO Type Double row tapered roller bearings provide a stiff bearing arrangement.
• Geseran 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. In addition, the bearings can better maintain preload and run at reduced noise levels.
• Hayat perkhidmatan yang panjang
  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 TDO 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.
