How the YET-207 model number is decoded

The YEL2 series order number YET 207 is a SKF insert bearing (Y-bearing) for a 35 mm shaft: eccentric-locking-collar insert bearing with a one-side-extended inner ring, built to the ISO 15 diameter-series envelope with a sphered OD of 72 mm. Inside sits a sealed ball insert with an eccentric collar on the extended ring: collar bite locks the shaft, the contact seals retain the life grease, and the spherical OD floats in the Y-housing. YET means collar locking instead of grub screws — fit the eccentric collar, turn it in the rotation direction until it grips, then lock the collar's own setscrew; the inner ring is extended on one side. the size code 207 carries the usual bore arithmetic — 35 mm (code 07 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. with no -2F/-2RF suffix the order number denotes the open external execution of the YEL2 size — add external exclusion at the housing and plan relubrication intervals for dusty or wet surroundings. Envelope 35x72x25.4 mm (1.378x2.835x1 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 460 g. Fillet discipline: the printed r_min 1 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 35x72 mm insert on its chamfer tilts the whole spherical seat. 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 — most belt-driven mounted-unit loads sit comfortably under 2.569 % of C. Spherical-seat note in numbers: the 72 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 53.5 = 168.075 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Capacity density: 25.5 kN from 0.460 kg of bearing steel is about 55.435 kN per kilogram, and per width millimetre the 25.4 mm unit carries 1.004 kN of dynamic capacity. Static-first planning: the 0.602 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 35 mm shaft, not the 25.5 kN L10 value. 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. Direction rule for YET-207: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 35 mm shaft must be free of burrs under the collar or the eccentric cannot bed flat.

Typical equipment & failure modes

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.
• 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.
• The eccentric collar is handed to running direction; fit it wrong on the 35 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Ordering discipline for the 35 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.
