How the YEL-212-2F model number is decoded

YEL 212-2F is SKF's 60 mm-bore eccentric-locking-collar insert bearing with the inner ring extended on both sides in the YEL2 series — a Y-bearing with a spherically ground outside surface for static self-alignment inside a matching SKF Y-housing, boundary dimensions 60x110x61.9 mm. The deep-groove ball set is built into an extended inner ring carrying a separate eccentric locking collar; turning the collar against its eccentric seat pinches the shaft, and the sphered outer ring self-aligns in the housing. the YEL prefix identifies the eccentric-locking-collar design: a separate eccentric collar turns against a matching eccentric on the extended inner ring to pinch the shaft, extended both sides. 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. suffix -2F means an NBR rubber contact seal plus a plain pressed-steel flinger on EACH side: the lip rides the extended inner ring while the flinger sheds coarse contamination before it reaches the lip. Envelope 60x110x61.9 mm (2.362x4.331x2.437 in), outer ring 26 mm wide, C 52.7 kN, C0 36 kN, Pu 1.53 kN. Mounted width B1 77.8 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 3,400 r/min; mass 1700 g. Fatigue-limit check: Pu 1.53 kN is the equivalent-load threshold under which the SKF adjusted-rating model credits very long life for YEL 212-2F — most belt-driven mounted-unit loads sit comfortably under 2.903 % of C. Bore-to-OD planning: OD 110 over bore 60 is a 1.833x step, while bore/overall-width gives 0.969; the spherical seat in the matching Y-housing must be specified to the 110 mm OD, not to a cylindrical housing bore. The s1 46.8 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. Static-first planning: the 0.582 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 60 mm shaft, not the 52.7 kN L10 value. Speed ceiling of 3,400 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. Two-side sealed collar note: after driving the eccentric collar tight, lock the collar set screw against its recess and verify the collar cannot be turned by hand; a collar that was merely pressed on without the eccentric bite spins on the shaft and frets it within hours. Direction rule for YEL-212-2F: 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

• 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.
• 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 77.8 mm includes collar space — a housing sized for a grub-screw insert of the same OD can be too narrow axially for the YEL collar.
• Catalogue ratings belong to YEL 212-2F as the ecc two f execution; other order numbers of the YEL 212 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.
