How the 32214-DF model number is decoded
The SKF 32214/DF is a 70×125×66.5 mm matched tapered-roller set — two single-row bearings in face-to-face (X) matched pair arrangement, ground and shipped together with the axial clearance fixed at the factory.Reading the designation: 32214 is the ISO 355 single-row base bearing (70 mm bore), and the suffix /DF marks the matched-set execution — arrangement, spacer grinding and factory clearance class. The pair envelope is 70×125×66.5 mm; the width covers both bearings of the set. In the face-to-face (X) arrangement the load lines of the two bearings converge toward the shaft axis: the set tolerates shaft deflection and thermal growth better than a back-to-back pair, but is less stiff against overturning moments. The 66.5 mm overall width of 32214-DF is the axial space the pair occupies. Dividing the pair C 334 kN by the 70 mm bore gives 4.77 kN per millimetre of journal for the complete arrangement — a density metric that compares matched sets across the face-to-face (X) matched pair family. Dimensional interchange map: within its boundary plan the 70×125×66.5 mm envelope of 32214-DF is fixed, so shoulder, spacer and seal drawings can be dimensioned straight from the catalogue table. Load sharing in 32214-DF 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 /DF set needs no setting adjustment at mounting: the clearance is built in; the assembler's job is clean seats, correct fits (k5 on a 70 mm rotating shaft) and square abutments.
Typical equipment & failure modes
Common applications
- large process pump and compressor shafts
- rolling-mill auxiliary drives
- crane sheave and hoist gearboxes
- large process pump and compressor shafts
Known failure patterns
- false brinelling on idle paired sets exposed to machine vibration
- roller large-end smearing against the cone rib after EP lubricant film failure
- pressed-steel cage wear or fracture after prolonged running above the limiting speed
- edge loading from shaft deflection or housing misalignment
- hard-particle indentation of the tapered raceway in unfiltered oil
Selection pitfalls — read before you substitute
- Replace 32214-DF as a complete set: pairing a new bearing with a worn partner leaves the clearance undefined even when the designation matches.
- Setting is built into 32214-DF; the classic field error is re-adjusting a matched pair as if it were two loose single bearings, which destroys the /DF clearance class.
- Clamp the 32214-DF pair axially through the cones, never through the rollers; pressing force across the roller complement brinells the raceways of both bearings at once.
- The 334/415 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 32214/DF designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of 32214-DF?
The SKF 32214/DF is a matched pair of single-row tapered roller bearings in face-to-face (X) matched pair arrangement with 70 mm bore, 125 mm outer diameter and 66.5 mm overall width (2.756 × 4.921 × 2.618 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 334 kN, C0 415 kN, fatigue load limit Pu 49 kN, reference speed 3,400 r/min, limiting speed 5,300 r/min, mass about 3.30 kg.
What does the /DF suffix on 32214-DF mean?
The base 32214 is the ISO 355 single-row bearing; the /DF suffix marks the matched-set execution — the arrangement (face-to-face (X)), 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 32214-DF for one bearing or the pair?
They are for the complete matched pair: C 334 kN dynamic and C0 415 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 32214 table values.
Can 32214-DF 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 70 mm shaft) and axial clamping through the cones; re-setting in the field destroys the matched clearance class.
When should a face-to-face (X) matched set be chosen?
Choose the face-to-face (X) set where the shaft grows thermally or alignment is imperfect — the converging load lines tolerate deflection. It is the default choice for wheel hubs and general gearbox shafts at the 70 mm bore.
