How the T7FC050T69-DTC10 model number is decoded
Lubrication for the pair should be sized against the combined 69 mm width and 2750 g mass: two roller sets sweep twice the contact area of a single bearing of the same bore.SKF T7FC 050T69/DTC10 belongs to the SKF matched tapered-roller range — the 50 mm bore entry in tandem matched pair arrangement, dimensioned 105 mm OD and 69 mm overall width for the pair.Digit by digit, T7FC050T69-DTC10 reads as the ISO 355 base bearing T7FC 050T69 supplied as a tandem matched pair matched pair (/DT); the 50 mm bore and 105 mm OD are per-bearing, the 69 mm width is for the set. Tandem pairing is the high-one-direction-thrust solution: the two cones of T7FC050T69-DTC10 share the axial load through the ground spacer, and the set is used where a single bearing of the 50 mm bore cannot carry the thrust component. Selection arithmetic: the catalogue C 229 kN and C0 275 kN are ratings of the complete pair, not of one bearing — never halve them back to a single-row figure when checking L10 life, and use the pair Pu 31.5 kN as the fatigue floor. Operating context for the 50 mm bore: a shaft of this diameter typically runs in the medium-bore band of industrial duty, and the 105 mm OD places the housing shoulder near 113 mm outer abutment. Load sharing in T7FC050T69-DTC10 depends on spacer face parallelism; a cocked spacer concentrates the reversing thrust on one bearing of the pair and shows up as asymmetric raceway wear at overhaul.
Typical equipment & failure modes
Common applications
- axle-boxes in material-handling equipment
- automotive and light-truck wheel hubs
- industrial gearbox shafts and reducers
- machine-tool spindles
Known failure patterns
- uneven load sharing in a pair when spacer faces are not parallel to the bore
- uneven load sharing in a pair when spacer faces are not parallel to the bore
- pressed-steel cage wear or fracture after prolonged running above the limiting speed
- rolling-contact fatigue spalling after the rated L10 life is exceeded
- hard-particle indentation of the tapered raceway in unfiltered oil
Selection pitfalls — read before you substitute
- A matched /DT set is ground as one system: never separate the two bearings of T7FC050T69-DTC10 or swap the spacer — the factory clearance is lost the moment the set is broken.
- Setting is built into T7FC050T69-DTC10; the classic field error is re-adjusting a matched pair as if it were two loose single bearings, which destroys the /DT clearance class.
- Spacer faces must stay parallel within the set's own tolerance; a tilted spacer in T7FC050T69-DTC10 concentrates reversing thrust on one bearing and shows up as one-sided raceway wear.
- The 229/275 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 T7FC 050T69/DTC10 designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of T7FC050T69-DTC10?
The SKF T7FC 050T69/DTC10 is a matched pair of single-row tapered roller bearings in tandem matched pair arrangement with 50 mm bore, 105 mm outer diameter and 69 mm overall width (1.969 × 4.134 × 2.717 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 229 kN, C0 275 kN, fatigue load limit Pu 31.5 kN, reference speed 3,600 r/min, limiting speed 6,300 r/min, mass about 2.75 kg.
What does the /DT suffix on T7FC050T69-DTC10 mean?
The base T7FC 050T69 is the ISO 355 single-row bearing; the /DT suffix marks the matched-set execution — the arrangement (tandem), 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 T7FC050T69-DTC10 for one bearing or the pair?
They are for the complete matched pair: C 229 kN dynamic and C0 275 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 T7FC 050T69 table values.
Can T7FC050T69-DTC10 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 (k5 on a rotating 50 mm shaft) and axial clamping through the cones; re-setting in the field destroys the matched clearance class.
When should a tandem matched set be chosen?
Choose the tandem set where one-direction thrust exceeds a single bearing's capacity — the two rows share the thrust, while a separate opposing bearing or set must cover the other direction.
