How the YET-207-106 model number is decoded

The YEL2 series order number YET 207-106 is a SKF insert bearing (Y-bearing) for a 34.925 mm (1.375 in) 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. inch bore code -106 decodes as 1" +6/16, i.e. 34.925 mm; the metric coded size YET 207 shares the same envelope but its bore is the metric value, not this one. 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 34.925x72x25.4 mm (1.375x2.835x1 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. 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). Rating split for the maintenance file: dynamic 25.5 kN (L10), static 15.3 kN (s0 shock check), fatigue 0.655 kN (adjusted life) — three separate uses for YET 207-106, none interchangeable with another. Speed ceiling of 5,300 r/min is the catalogue mechanical limit for THIS execution; seal lip and flinger drag, not steel fatigue, are normally what cap it, so real fan duty is planned well below it. Imperial procurement cross-check: 1.375 in bore, 2.835 in OD, 1 in overall width; the 460 g mass converts to 0.460 kg (16.2 oz) for the bill of materials. Grease-life arithmetic is dominated by speed: at dn approx 2.83x10^5 the sealed-for-life fill is planned for the catalogue's grease-life regime, which is why the limiting speed and the relubrication interval move together, and high-temperature mounts shorten both even when load is light. 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

• 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 34.925 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Ordering discipline for the 34.925 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.
