How the BT2-8009-HA3 model number is decoded
At 165.0 kg the BT2-8009-HA3 assembly needs mechanical handling at mounting — sling through the bore or use lifting eyes on the shaft, and never lift the unit by one ring alone: the rings are separable. The catalogue publishes no speed ratings for this size class — permissible speed is set by the application thermal balance; plan lubrication and cooling against the 165.0 kg mass and the 560 mm OD surface. Operating context for the 380 mm bore: a shaft of this diameter typically runs in the xl-bore band of industrial duty, and the 560 mm OD places the housing shoulder near 568 mm outer abutment. Ordering discipline for BT2-8009-HA3: quote base number and TDIS/NY variant together — the base alone is ambiguous because several internal executions share the same 380 mm bore boundary. In the TDI O-arrangement the spread of the two rows of BT2-8009-HA3 gives high moment stiffness; the cups must be free to float microscopically in the housing so shaft thermal growth does not consume the factory clearance.In SKF catalogue PUB BU/P1 17000, BT2-8009-HA3 appears as SKF BT2-8009/HA3: a TDI-design double-row tapered roller bearing for a 380 mm shaft, rated C 1617 kN in the TDIS/NY execution.Reading the designation: BT2-8009 is the SKF double-row base number tied to the 380 mm bore and 560 mm OD, and the TDIS/NY suffix identifies the internal design variant — cup/cone configuration, spacer execution and clearance class are encoded there rather than in a generic suffix.
Typical equipment & failure modes
Common applications
- heavy-duty rolling-mill gearboxes
- large crusher and mineral-processing drives
- wind-turbine main shafts
- large industrial mixer shafts
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
- rib-roller contact scoring from loss of the EP additive film
- hard-particle indentation of the tapered raceway in unfiltered oil
Selection pitfalls — read before you substitute
- The 380 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 BT2-8009-HA3.
- The 380 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 BT2-8009-HA3.
- Do not mix components between units of the same BT2-8009 base number: cones, cups and spacers are matched per serial — interchange only complete assemblies.
- The 1617/6550 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 BT2-8009/HA3 designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of BT2-8009-HA3?
The SKF BT2-8009/HA3 is a double-row tapered roller bearing of TDI design with 380 mm bore, 560 mm outer diameter and 200 mm overall width (14.961 × 22.047 × 7.874 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 1617 kN, C0 6550 kN, fatigue load limit Pu 520 kN, mass about 165.00 kg.
What does the TDIS/NY variant code on BT2-8009-HA3 mean?
Double-row tapered bearings of this size follow SKF works numbering: the base number BT2-8009 fixes the 380×560×200 mm envelope, and the TDIS/NY 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 BT2-8009-HA3?
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 165.0 kg assembly mass and instrument the first run with temperature logging.
Can components of BT2-8009-HA3 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 BT2-8009-HA3 as a complete assembly in the same TDIS/NY variant.
How does BT2-8009-HA3 react axial load?
The TDI design works as a fixed O arrangement: one double cone between two single cups gives a wide load spread and high moment stiffness while reacting thrust in both directions through the two rows.
