How the BT2-8010-HA3VA901 model number is decoded
Journal and housing interface: the 386 mm bore takes a m6 shaft seat and the 574 mm outside diameter pairs with an H7 housing bore; the 220 mm width defines shoulder depth and the 185000 g mass is the dead load in thermal-growth calculations. Variant check: catalogue siblings of BT2-8010-HA3VA901 carry different variant suffixes at the same boundary dimensions; the TDIS/NVY code on this unit is not a cosmetic mark — it fixes the internal setting and must match on replacement. TDI mounting: the double cone takes the m6 shaft seat at 386 mm bore, and the two single cups are seated separately in the housing — check cup-face contact around the full circumference before axial clamping.SKF BT2-8010/HA3VA901 belongs to the SKF TDI double-row range — the 386 mm bore entry with a 574 mm outside diameter and 220 mm overall width, typical for rolling-mill and heavy industrial shafts.On the SKF nameplate, BT2-8010-HA3VA901 reads as base BT2-8010 in the TDIS/NVY design variant; boundary dimensions 386×574×220 mm come from the base number, while clearance setting and spacer style come from the variant. Substitution checkpoint: another brand's double-row unit of the same 386×574×220 mm envelope may carry a different internal clearance class — match the TDIS/NVY execution meaning, not just the boundary dimensions, before swapping. Static check: with C0 6550 kN the unit carries shock and standstill load up to the static safety factor of the application; the 510 kN Pu governs the fatigue side of the same calculation.
Typical equipment & failure modes
Common applications
- large crusher and mineral-processing drives
- wind-turbine main shafts
- marine propulsion gearboxes
- wind-turbine main shafts
Known failure patterns
- brinelling of both raceways when mounting force is transmitted through the roller complement
- thermal clearance loss when housing cooling is undersized for two rows of tapered contact
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- mounting score marks when the cone is cocked over the shaft keyway or a burr
- electrical pitting on VFD-driven shafts without grounding protection
Selection pitfalls — read before you substitute
- The 386 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 BT2-8010-HA3VA901.
- The 386 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 BT2-8010-HA3VA901.
- Contamination control matters twice over for double-row units: particles trapped between the rows of BT2-8010-HA3VA901 cannot migrate out, so flush the housing before assembly and fit filtration matched to the oil flow.
- The 2967/6550 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 BT2-8010/HA3VA901 designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of BT2-8010-HA3VA901?
The SKF BT2-8010/HA3VA901 is a double-row tapered roller bearing of TDI design with 386 mm bore, 574 mm outer diameter and 220 mm overall width (15.197 × 22.598 × 8.661 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 2967 kN, C0 6550 kN, fatigue load limit Pu 510 kN, mass about 185.00 kg.
What does the TDIS/NVY variant code on BT2-8010-HA3VA901 mean?
Double-row tapered bearings of this size follow SKF works numbering: the base number BT2-8010 fixes the 386×574×220 mm envelope, and the TDIS/NVY 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 BT2-8010-HA3VA901?
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 185.0 kg assembly mass and instrument the first run with temperature logging.
Can components of BT2-8010-HA3VA901 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 BT2-8010-HA3VA901 as a complete assembly in the same TDIS/NVY variant.
How does BT2-8010-HA3VA901 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.
