How the 332169AA model number is decoded
The SKF 332169 AA is a 305.07×500×200 mm TDI double-row tapered roller bearing — a double cone with two cups, delivered clearance-set as one assembly weighing 150.0 kg.On the SKF nameplate, 332169AA reads as base 332169 in the TDIS/NY design variant; boundary dimensions 305.07×500×200 mm come from the base number, while clearance setting and spacer style come from the variant. Wear pattern reading at overhaul: the two rows of 332169AA should show symmetric raceway contact; one-sided wear points to housing misalignment or a cocked seat rather than to a material defect. Static check: with C0 5200 kN the unit carries shock and standstill load up to the static safety factor of the application; the 425 kN Pu governs the fatigue side of the same calculation. Operating context for the 305.07 mm bore: a shaft of this diameter typically runs in the xl-bore band of industrial duty, and the 500 mm OD places the housing shoulder near 508 mm outer abutment. Ordering discipline for 332169AA: quote base number and TDIS/NY variant together — the base alone is ambiguous because several internal executions share the same 305.07 mm bore boundary. In the TDI O-arrangement the spread of the two rows of 332169AA 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.
Typical equipment & failure modes
Common applications
- heavy-duty rolling-mill gearboxes
- large crusher and mineral-processing drives
- wind-turbine main shafts
- heavy-duty rolling-mill gearboxes
Known failure patterns
- axial clamping ring bolt relaxation that lets the clearance-set rows walk apart under reversing thrust
- thermal clearance loss when housing cooling is undersized for two rows of tapered contact
- pressed-steel cage wear or fracture after prolonged running above the limiting speed
- rib-roller contact scoring from loss of the EP additive film
- mounting score marks when the cone is cocked over the shaft keyway or a burr
Selection pitfalls — read before you substitute
- Do not mix components between units of the same 332169 base number: cones, cups and spacers are matched per serial — interchange only complete assemblies.
- Lifting 332169AA by one ring separates the assembly; sling through the 305.07 mm bore or use the shaft as the lifting member.
- Do not mix components between units of the same 332169 base number: cones, cups and spacers are matched per serial — interchange only complete assemblies.
- The 2734/5200 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 332169 AA designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of 332169AA?
The SKF 332169 AA is a double-row tapered roller bearing of TDI design with 305.07 mm bore, 500 mm outer diameter and 200 mm overall width (12.011 × 19.685 × 7.874 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 2734 kN, C0 5200 kN, fatigue load limit Pu 425 kN, mass about 150.00 kg.
What does the TDIS/NY variant code on 332169AA mean?
Double-row tapered bearings of this size follow SKF works numbering: the base number 332169 fixes the 305.07×500×200 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 332169AA?
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 150.0 kg assembly mass and instrument the first run with temperature logging.
Can components of 332169AA 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 332169AA as a complete assembly in the same TDIS/NY variant.
How does 332169AA 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.
