How the BT2B332754 model number is decoded

Dividing C 3270 kN by the 368.3 mm bore gives 8.88 kN per millimetre of journal — heavy-section density typical of double-row tapered units built for slow, heavily loaded shafts. Cross-section geometry: the 114.3 mm half-section ((596.9−368.3)/2) places the roller pitch diameter near 482 mm, and the 203.2 mm axial width sets the abutment depth — geometry that fixes the contact angle behaviour of BT2B332754. When cross-referencing BT2B332754, note that the TDO/XDC variant is part of the SKF works designation: same-envelope units under another variant code can differ in clearance class and load rating even though d/D/T match. In the TDO X-arrangement the two cones of BT2B332754 locate the shaft in both axial directions; the housing seat for the 596.9 mm double cup is a loose-to-transition fit so thermal growth does not preload the rows.In SKF catalogue PUB BU/P1 17000, BT2B332754 appears as SKF BT2B 332754: a TDO-design double-row tapered roller bearing for a 368.3 mm shaft, rated C 3270 kN with the factory-set internal clearance of the TDO/XDC variant.The code SKF BT2B 332754 is not an ISO 355 number: double-row tapered bearings of this size follow SKF works numbering, where BT2B 332754 fixes the 368.3×596.9×203.2 mm envelope and the variant suffix (TDO/XDC) fixes the internal execution. Lubrication planning: two roller rows inside a 596.9 mm OD envelope sweep a large contact area per revolution; oil circulation or a defined grease-relubrication interval should be sized against the 188.0 kg assembly mass.

Typical equipment & failure modes

Common applications

  • rolling-mill roll-neck bearings
  • heavy-duty rolling-mill gearboxes
  • large crusher and mineral-processing drives
  • offshore winch and drawworks drums

Known failure patterns

  • water or scale ingress at the separable ring parting lines in roll-neck service
  • water or scale ingress at the separable ring parting lines in roll-neck service
  • cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
  • edge loading from shaft deflection or housing misalignment
  • grease degradation after long shelf storage without rotation or re-greasing

Selection pitfalls — read before you substitute

  • Contamination control matters twice over for double-row units: particles trapped between the rows of BT2B332754 cannot migrate out, so flush the housing before assembly and fit filtration matched to the oil flow.
  • The 368.3 mm bore seat must be checked for ovality before mounting — at this size a worn seat lets the cone creep, and fretting debris then works between the rows of BT2B332754.
  • Lifting BT2B332754 by one ring separates the assembly; sling through the 368.3 mm bore or use the shaft as the lifting member.
  • The 3270/5850 kN ratings are SKF catalogue 17000 values for this execution; SKF can revise internal geometry without changing the order number, so keep the catalogue version (PUB BU/P1 17000/1 EN, 2018) with the specification.
  • Quote the full SKF BT2B 332754 designation when purchasing — base-number-only orders are ambiguous across executions and variants.

Frequently asked questions

What are the dimensions and catalogue data of BT2B332754?

The SKF BT2B 332754 is a double-row tapered roller bearing of TDO design with 368.3 mm bore, 596.9 mm outer diameter and 203.2 mm overall width (14.5 × 23.5 × 8 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 3270 kN, C0 5850 kN, fatigue load limit Pu 465 kN, mass about 188.00 kg.

What does the TDO/XDC variant code on BT2B332754 mean?

Double-row tapered bearings of this size follow SKF works numbering: the base number BT2B 332754 fixes the 368.3×596.9×203.2 mm envelope, and the TDO/XDC code identifies the internal design variant — spacer execution, rib detail and clearance class. Same-envelope units under a different variant are not interchangeable without checking the variant meaning.

Why does the catalogue list no speed rating for BT2B332754?

Bearings of this size class run in slow, heavily loaded machinery where the permissible speed is set by the application heat balance rather than a universal table value. Plan lubrication and cooling against the 188.0 kg assembly mass and instrument the first run with temperature logging.

Can components of BT2B332754 be interchanged with another unit of the same base number?

No — cones, cups and spacers of a double-row set are matched per serial and the clearance is set by selective grinding at the factory. Replace BT2B332754 as a complete assembly in the same TDO/XDC variant.

How does BT2B332754 react axial load?

The TDO design works as a fixed X arrangement: one double cup with two cones locates the shaft in both axial directions, with load shared between the two rows according to the factory-set clearance.
