How the 332169A model number is decoded
In SKF catalogue PUB BU/P1 17000, 332169A appears as SKF 332169 A: a TDI-design double-row tapered roller bearing for a 305.07 mm shaft, rated C 2734 kN in the TDIS/N execution.On the SKF nameplate, 332169A reads as base 332169 in the TDIS/N design variant; boundary dimensions 305.07×500×200 mm come from the base number, while clearance setting and spacer style come from the variant. The 200 mm ring width within the 200 mm overall width is the space taken by the centre element of the set; abutment and spacer drawings should be dimensioned from the catalogue width table, not scaled from a single-row bearing. Selection arithmetic: C 2734 kN and C0 5200 kN are ratings of the complete double-row unit, giving a C0/C balance of 1.90; the fatigue load limit Pu 425 kN is the floor for the adjusted-life calculation at the 305.07 mm bore. Journal and housing interface: the 305.07 mm bore takes a m6 shaft seat and the 500 mm outside diameter pairs with an H7 housing bore; the 200 mm width defines shoulder depth and the 150000 g mass is the dead load in thermal-growth calculations. Variant check: catalogue siblings of 332169A carry different variant suffixes at the same boundary dimensions; the TDIS/N 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 305.07 mm bore, and the two single cups are seated separately in the housing — check cup-face contact around the full circumference before axial clamping.
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
- water or scale ingress at the separable ring parting lines in roll-neck service
- brinelling of both raceways when mounting force is transmitted through the roller complement
- 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
- hard-particle indentation of the tapered raceway in unfiltered oil
Selection pitfalls — read before you substitute
- Contamination control matters twice over for double-row units: particles trapped between the rows of 332169A cannot migrate out, so flush the housing before assembly and fit filtration matched to the oil flow.
- Contamination control matters twice over for double-row units: particles trapped between the rows of 332169A cannot migrate out, so flush the housing before assembly and fit filtration matched to the oil flow.
- Never adjust the clearance of 332169A in the field: the two rows are set by ground spacers at the factory, and shim experiments on a 150.0 kg assembly usually end in overheated rows.
- 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 A designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of 332169A?
The SKF 332169 A 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/N variant code on 332169A 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/N 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 332169A?
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 332169A 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 332169A as a complete assembly in the same TDIS/N variant.
How does 332169A 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.
