How the T7FC045T62-DTC10 model number is decoded
Load sharing in T7FC045T62-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. A matched /DT set needs no setting adjustment at mounting: the clearance is built in; the assembler's job is clean seats, correct fits (k5 on a 45 mm rotating shaft) and square abutments.For a 45 mm shaft carrying reversing axial load, SKF lists T7FC045T62-DTC10 under catalogue execution SKF T7FC 045T62/DTC10: a factory-matched tandem matched pair tapered-roller pair, set and measured as one unit.Numbering ties the set to its envelope: base T7FC 045T62 fixes the 45 mm bore and 95 mm OD of each bearing, the /DT suffix fixes the arrangement and setting, and the catalogue 62 mm width is the combined pair dimension. In the tandem arrangement both bearings face the same way, so one-direction thrust is shared by two rows: T7FC045T62-DTC10 roughly doubles the single-bearing axial capacity in one direction while a separate opposing bearing or set must react thrust the other way. Dividing the pair C 189 kN by the 45 mm bore gives 4.20 kN per millimetre of journal for the complete arrangement — a density metric that compares matched sets across the tandem matched pair family. Material and manufacturing detail: the 2050 g catalogue mass reflects through-hardened bearing steel machined to the listed envelope; ring roundness and width tolerance keep the mounted-setting scatter inside the catalogue class.
Typical equipment & failure modes
Common applications
- belt-driven fan and blower shafts
- axle-boxes in material-handling equipment
- automotive and light-truck wheel hubs
- industrial gearbox shafts and reducers
Known failure patterns
- axial overload spalling at the roller-rib contact beyond the single-row thrust rating
- uneven load sharing in a pair when spacer faces are not parallel to the bore
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- rib-roller contact scoring from loss of the EP additive film
- electrical pitting on VFD-driven shafts without grounding protection
Selection pitfalls — read before you substitute
- Setting is built into T7FC045T62-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.
- Clamp the T7FC045T62-DTC10 pair axially through the cones, never through the rollers; pressing force across the roller complement brinells the raceways of both bearings at once.

- The 189/224 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 045T62/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 T7FC045T62-DTC10?
The SKF T7FC 045T62/DTC10 is a matched pair of single-row tapered roller bearings in tandem matched pair arrangement with 45 mm bore, 95 mm outer diameter and 62 mm overall width (1.772 × 3.74 × 2.441 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 189 kN, C0 224 kN, fatigue load limit Pu 25.5 kN, reference speed 4,000 r/min, limiting speed 7,000 r/min, mass about 2.05 kg.
What does the /DT suffix on T7FC045T62-DTC10 mean?
The base T7FC 045T62 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 T7FC045T62-DTC10 for one bearing or the pair?
They are for the complete matched pair: C 189 kN dynamic and C0 224 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 045T62 table values.
Can T7FC045T62-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 45 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.
