How the 32236T192-DB model number is decoded
A matched /DB set needs no setting adjustment at mounting: the clearance is built in; the assembler's job is clean seats, correct fits (m6 on a 180 mm rotating shaft) and square abutments.32236T192-DB (SKF 32236T192/DB) is the back-to-back (O) matched pair matched-set choice for a 180 mm shaft: a pair of tapered roller bearings whose combined envelope is 320×192 mm, delivered ready to mount with controlled internal clearance.Reading the designation: 32236T192 is the ISO 355 single-row base bearing (180 mm bore), and the suffix /DB marks the matched-set execution — arrangement, spacer grinding and factory clearance class. The pair envelope is 180×320×192 mm; the width covers both bearings of the set. In the back-to-back (O) arrangement the load lines diverge toward the shaft axis, giving the pair a wide effective spread: 32236T192-DB resists overturning moments and tilting loads stiffly, which is why O-sets are preferred for gearbox output shafts and pinion supports. Catalogue mass 61000 g covers both bearings and the ground spacer of 32236T192-DB; keep the set complete — substituting one bearing or a non-ground spacer destroys the factory clearance. Load system: C 1833 kN against C0 3250 kN gives a 1.77 balance, and 10.18 kN of dynamic capacity per millimetre of the 180 mm bore is the density figure to compare against neighbouring sizes. When a matched /DB set like 32236T192-DB is replaced, replace the whole set: mixing a new bearing with a worn partner from the old set leaves the clearance and load sharing of the pair undefined.
Typical equipment & failure modes
Common applications
- offshore winch and drawworks drums
- rolling-mill roll-neck bearings
- heavy-duty rolling-mill gearboxes
- marine propulsion gearboxes
Known failure patterns
- preload loss as the mounted pair relaxes, letting rollers skid and smear the raceways
- axial overload spalling at the roller-rib contact beyond the single-row thrust rating
- 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
- electrical pitting on VFD-driven shafts without grounding protection
Selection pitfalls — read before you substitute
- Clamp the 32236T192-DB pair axially through the cones, never through the rollers; pressing force across the roller complement brinells the raceways of both bearings at once.
- Spacer faces must stay parallel within the set's own tolerance; a tilted spacer in 32236T192-DB concentrates reversing thrust on one bearing and shows up as one-sided raceway wear.
- Clamp the 32236T192-DB pair axially through the cones, never through the rollers; pressing force across the roller complement brinells the raceways of both bearings at once.
- The 1833/3250 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 32236T192/DB designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of 32236T192-DB?
The SKF 32236T192/DB is a matched pair of single-row tapered roller bearings in back-to-back (O) matched pair arrangement with 180 mm bore, 320 mm outer diameter and 192 mm overall width (7.087 × 12.598 × 7.559 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 1833 kN, C0 3250 kN, fatigue load limit Pu 300 kN, reference speed 1,100 r/min, limiting speed 1,900 r/min, mass about 61.00 kg.
What does the /DB suffix on 32236T192-DB mean?
The base 32236T192 is the ISO 355 single-row bearing; the /DB suffix marks the matched-set execution — the arrangement (back-to-back (O)), the ground spacer and the factory-set axial clearance class. A matched set cannot be assembled from loose single bearings; quote the full designation when ordering.
Are the C and C0 ratings of 32236T192-DB for one bearing or the pair?
They are for the complete matched pair: C 1833 kN dynamic and C0 3250 kN static already include load sharing between the two bearings. Do not halve them for single-bearing checks, and do not compare them directly with the single-row 32236T192 table values.
Can 32236T192-DB be adjusted like two loose tapered bearings?
No — the axial clearance is set at the factory by selective spacer grinding. Mounting work is limited to clean seats, correct fits (m6 on a rotating 180 mm shaft) and axial clamping through the cones; re-setting in the field destroys the matched clearance class.
When should a back-to-back (O) matched set be chosen?
Choose the back-to-back (O) set where moment stiffness dominates — pinion supports, gearbox output shafts, crane sheaves. The diverging load lines give the widest effective spread at the 180 mm bore.
