How the YET-206-102 model number is decoded
Listed in SKF 17000 chapter 2, YET 206-102 is a eccentric-locking-collar insert bearing with a one-side-extended inner ring, 28.575x62x23.8 mm overall, whose convex spherical outer ring pivots in the spherical bore of a Y-pillow, Y-flange or take-up housing. Construction pairs capped deep-groove geometry with a one-piece eccentric locking collar and a convex outer ring — quick to mount on plain commercial shafts and tolerant of initial static misalignment. reading YET: an eccentric locking collar does the shaft clamping (popular where shaft tolerance and quick removal matter), inner ring extended on one side. for inch shafts the order number carries the bore as whole-inches plus sixteenths: -102 = 28.575 mm, which is why this row sits beside, not on, the metric bore size. the bare designation means no factory seal package: unlike the -2F executions this bearing relies on enclosure by the Y-housing and its own re-greasing path, which is why it is normally specified inside well-sealed plummer and flange units. Envelope 28.575x62x23.8 mm (1.125x2.441x0.937 in), outer ring 18 mm wide, C 19.5 kN, C0 11.2 kN, Pu 0.475 kN. Mounted width B1 35.7 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 6,300 r/min; mass 340 g. The s1 26.7 mm dimension is printed for the locking zone — the set-screw/collar seating reference — and it is verified at mounting, not recoverable from d/D/B alone. Load balance for documentation: C0 11.2 kN against C 19.5 kN gives a 0.574 ratio; mounted-unit positions with shock and standstill loading are normally checked on C0, while conveyor and fan duty are evaluated on the L10 figure. Outer-vs-overall width: the outer ring is 18 mm wide inside the 23.8 mm total, so the extended inner ring accounts for 0.244 of the overall width (5.8 mm of axial projection on the locking side). Fillet discipline: the printed r_min 0.6 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 28.575x62 mm insert on its chamfer tilts the whole spherical seat. Envelope arithmetic: the radial section from 28.575 mm bore to 62 mm OD is 16.712 mm; dividing C 19.5 kN by that section gives 1.167 kN per section millimetre, and the 23.8 mm overall width is 1.424x the section. One-side collar note: the eccentric collar mounts on the extended side only and must turn in the shaft rotation direction to self-tighten; on reversing drives this design can loosen by design intent — choose grub-screw or ConCentra locking for true bidirectional shafts. Collar geometry for this size: over the 18 mm outer-ring width the inner ring runs to 23.8 mm overall (35.7 mm including the eccentric collar width), giving the collar its eccentric seating face clear of the seal.
Typical equipment & failure modes
Common applications
- agricultural machinery PTO-driven shafts
- ventilation equipment with frequent bearing changes
- tiller and cultivator rotors
Known failure patterns
- collar forced on a reversing application repeatedly loads and unloads the eccentric, fretting both parts
- burr or paint under the eccentric faces prevents full bite, leaving an eccentric preload that runs hot
- pressure-greasing through the housing fitting at excessive pressure balloons the NBR seals out of their grooves
- water or slurry past the seal lip emulsifies the life-long grease and rusts the flinger recess
- two bearings of the same size but different locking styles swapped during overhaul — shaft preparation (dimples, collar space, sleeve seat) no longer matches
Selection pitfalls — read before you substitute
- Never pin or weld the eccentric collar: the controlled eccentric friction is the locking principle, and pinning turns a demountable insert into a shaft-replacement job.
- The eccentric collar is handed to running direction; fit it wrong on the 28.575 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
- Overall width 35.7 mm includes collar space — a housing sized for a grub-screw insert of the same OD can be too narrow axially for the YET collar.
- Ordering discipline for the 28.575 mm size: the chapter lists several executions side by side (YEL2 locking style x seal package x application variant); a bare-number substitution needs a fresh dimension, speed and rating check rather than a like-for-like assumption.
Frequently asked questions
What are the dimensions and catalogue data of YET-206-102?
The catalogue envelope is 28.575x62x23.8 mm with a spherical outside surface; mass 340 g. Ratings C 19.5/11.2 kN, Pu 0.475 kN, limiting speed 6,300 r/min.
What does the designation YET 206-102 mean?
reading YET: an eccentric locking collar does the shaft clamping (popular where shaft tolerance and quick removal matter), inner ring extended on one side. for inch shafts the order number carries the bore as whole-inches plus sixteenths: -102 = 28.575 mm, which is why this row sits beside, not on, the metric bore size. the bare designation means no factory seal package: unlike the -2F executions this bearing relies on enclosure by the Y-housing and its own re-greasing path, which is why it is normally specified inside well-sealed plummer and flange units.
What is the difference between YET and YEL?
YET has the inner ring extended on one side; YEL extends it on both sides. Both lock with the eccentric collar and share bore/OD geometry; the sealed -2F executions sit in the YEL listings.
Can eccentric-collar bearings run in both directions?
They are intended for one predominant running direction; true reversing drives can unwind the eccentric. For bidirectional or vibrating shafts choose grub-screw or SKF ConCentra (YSP) locking.
