How the YET-207-105 model number is decoded

Listed in SKF 17000 chapter 2, YET 207-105 is a eccentric-locking-collar insert bearing with a one-side-extended inner ring, 33.3375x72x25.4 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: -105 = 33.337 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 33.3375x72x25.4 mm (1.313x2.835x1 in), outer ring 19 mm wide, C 25.5 kN, C0 15.3 kN, Pu 0.655 kN. Mounted width B1 38.9 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 5,300 r/min; mass 490 g. Envelope arithmetic: the radial section from 33.3375 mm bore to 72 mm OD is 19.331 mm; dividing C 25.5 kN by that section gives 1.319 kN per section millimetre, and the 25.4 mm overall width is 1.314x the section. Bore-to-OD planning: OD 72 over bore 33.3375 is a 2.16x step, while bore/overall-width gives 1.313; the spherical seat in the matching Y-housing must be specified to the 72 mm OD, not to a cylindrical housing bore. Outer-vs-overall width: the outer ring is 19 mm wide inside the 25.4 mm total, so the extended inner ring accounts for 0.252 of the overall width (6.4 mm of axial projection on the locking side). Spherical-seat note in numbers: the 72 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 52.669 = 165.465 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Fatigue-limit check: Pu 0.655 kN is the equivalent-load threshold under which the SKF adjusted-rating model credits very long life for YET 207-105 — most belt-driven mounted-unit loads sit comfortably under 2.569 % of C. 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 19 mm outer-ring width the inner ring runs to 25.4 mm overall (38.9 mm including the eccentric collar width), giving the collar its eccentric seating face clear of the seal.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• The eccentric collar is handed to running direction; fit it wrong on the 33.3375 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Overall width 38.9 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.
• 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.
• Catalogue ratings belong to YET 207-105 as the ecc one open execution; other order numbers of the YET 207-105 size are different articles (open vs sealed, plain vs rubberized flinger, stainless vs carbon steel) and may carry different ratings or speeds — always quote the full designation.
