How the YET-212 model number is decoded

The YEL2 series order number YET 212 is a SKF insert bearing (Y-bearing) for a 60 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 110 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 212 carries the usual bore arithmetic — 60 mm (code 12 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 60x110x36.7 mm (2.362x4.331x1.445 in), outer ring 26 mm wide, C 52.7 kN, C0 36 kN, Pu 1.53 kN. Mounted width B1 52.6 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 3,400 r/min; mass 1350 g. Load balance for documentation: C0 36 kN against C 52.7 kN gives a 0.683 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. Selection figures for YET 212: C0/C is 0.683, Pu 1.53 kN is 2.903 % of the 52.7 kN dynamic rating, and the 1350 g catalogue mass works out to roughly 22.5 g per millimetre of the 60 mm bore. Bore-to-OD planning: OD 110 over bore 60 is a 1.833x step, while bore/overall-width gives 1.635; the spherical seat in the matching Y-housing must be specified to the 110 mm OD, not to a cylindrical housing bore. Fatigue-limit check: Pu 1.53 kN is the equivalent-load threshold under which the SKF adjusted-rating model credits very long life for YET 212 — most belt-driven mounted-unit loads sit comfortably under 2.903 % of C. Mass-to-load ratio for YET-212: 25.617 g of catalogue mass per rated kN of C, and 22.5 g per millimetre of bore — useful when comparing executions of the same 60x110 mm envelope on the drawing. 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-212: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 60 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.
• The eccentric collar is handed to running direction; fit it wrong on the 60 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Overall width 52.6 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 60 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.
