How the BT2B332767A model number is decoded
Operating context for the 101.6 mm bore: a shaft of this diameter typically runs in the large-bore band of industrial duty, and the 146.05 mm OD places the housing shoulder near 154 mm outer abutment. The TDO/D suffix on BT2B332767A is a design-variant code in the SKF double-row numbering system; it identifies which internal configuration sits inside the 101.6×146.05×49.212 mm envelope. TDO mounting: the double cup is clamped in the housing and the two cones take interference on the 101.6 mm shaft; press force goes through the cone faces only — driving through the rollers brinells both raceways at once.In SKF catalogue PUB BU/P1 17000, BT2B332767A appears as SKF BT2B 332767 A: a TDO-design double-row tapered roller bearing for a 101.6 mm shaft, rated C 267 kN with the factory-set internal clearance of the TDO/D variant.Digit by digit, BT2B332767A breaks into the base number BT2B 332767 — the 101.6×146.05×49.212 mm boundary — and the TDO/D variant code, which is part of the order designation and must be quoted in full at purchase. Lubrication planning: two roller rows inside a 146.05 mm OD envelope sweep a large contact area per revolution; oil circulation or a defined grease-relubrication interval should be sized against the 2.5 kg assembly mass. Static check: with C0 375 kN the unit carries shock and standstill load up to the static safety factor of the application; the 40.5 kN Pu governs the fatigue side of the same calculation.
Typical equipment & failure modes
Common applications
- heavy industrial gearboxes and speed reducers
- large process pump and compressor shafts
- rolling-mill auxiliary drives
- large process pump and compressor shafts
Known failure patterns
- water or scale ingress at the separable ring parting lines in roll-neck service
- unequal load sharing between the two roller rows when the centre spacer loses its factory grinding
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- grease degradation after long shelf storage without rotation or re-greasing
- mounting score marks when the cone is cocked over the shaft keyway or a burr
Selection pitfalls — read before you substitute
- Lifting BT2B332767A by one ring separates the assembly; sling through the 101.6 mm bore or use the shaft as the lifting member.
- Contamination control matters twice over for double-row units: particles trapped between the rows of BT2B332767A cannot migrate out, so flush the housing before assembly and fit filtration matched to the oil flow.

- The 267/375 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.

Frequently asked questions
What are the dimensions and catalogue data of BT2B332767A?
The SKF BT2B 332767 A is a double-row tapered roller bearing of TDO design with 101.6 mm bore, 146.05 mm outer diameter and 49.212 mm overall width (4 × 5.75 × 1.937 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 267 kN, C0 375 kN, fatigue load limit Pu 40.5 kN, mass about 2.45 kg.
What does the TDO/D variant code on BT2B332767A mean?
Double-row tapered bearings of this size follow SKF works numbering: the base number BT2B 332767 fixes the 101.6×146.05×49.212 mm envelope, and the TDO/D 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 BT2B332767A?
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 2.5 kg assembly mass and instrument the first run with temperature logging.
Can components of BT2B332767A 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 BT2B332767A as a complete assembly in the same TDO/D variant.
How does BT2B332767A 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.
